PUE Cable lines up to 220 kV

2.3.1. Refer to Chapter 1 of the Rules to extend to cable power lines up to 220 kV, as well as lines to be used with control cables. Cable lines are more and more vikonuyutsya for special projects. Dodatkovi vimogi to the cable lines in Ch. 7.3, 7.4 and 7.7.

2.3.25. When choosing methods of laying power cable lines up to 35 kV, it is necessary to step by step:

1. When laying cables near the ground, it is recommended to lay no more than six power cables in one trench. With a large number of cables, it is recommended to lay them near the edge of the trenches with groups of cables not less than 0.5 m, or in canals, tunnels, along side tracks and in galleries.

2. Laying of cables near tunnels, along walkways and in galleries is recommended when there are a number of power cables, going in one straight line, more than 20.

3. The laying of cables in blocks is stagnant in the minds of great density along the road, in times of flowing through the tracks and processes, when pouring metal, etc.

4. When choosing the ways of laying cables on the territory of the place of fault, the cob capital vitraty and vitraty are connected with the robotic exploitation and repair robots, as well as the handiness and economy of the equipment.

2.3.26. On the territory of the power plant, the lines of responsibility are laid in tunnels, ducts, channels, blocks, along the paths and in galleries. The laying of power cables in trenches is allowed only to all other ancillary facilities (paliva warehouses, mains) with no more than six. On the territory of the power plant, with a pulling force of up to 25 MW, it is also allowed to lay cables in trenches.

2.3.27. On the territory of industrial enterprises, cable lines of guilt are laid into the ground (in trenches), tunnels, blocks, canals, along the walkways, in galleries and along the walls of the week.

2.3.28. On the territory of the production stations and the auxiliary attachments of the cable lines, the lines of responsibility are laid in tunnels, ducts, channels, pipes, in the ground (in trenches), above-ground concrete trays, along walkways and in galleries.

2.3.29. In places and villages, single cable lines should be laid, as a rule, in the ground (in trenches) along unproblematic parts of streets (along sidewalks), in courtyards and technical smogs in the viglyadi lawns.

2.3.30. Along the streets and areas, filled with underground communes, the laying of cable lines in the number of 10 and more in the future, it is recommended to conduct in the collectors and cable tunnels. When the streets are overhauled and the area with good coverage and the intensive traffic collapse, the cable lines must be laid in blocks or pipes.

2.3.31. When equipped with cable lines in areas of frosty permafrost, there is a trace of physical phenomena, connected with the nature of bagatory permafrost: heaving soil, frost trenches, drought and so on. in a small sphere in dry, kindly draining soils, in piece rags from large-skeletal dry ground soils, in trays on the surface of the earth, on walkways. It is recommended to lay cables with pipes for heating, water supply, canalization, etc. In special sporums (collectors).

2.3.32. New types of cable laying in areas of deep permafrost can be carried out during the offensive:

1. For laying cables near earthen trenches with adherent soils є draining soils (skeln, pebbles, gravel, gravel and coarse sand); heaving and subsiding soils are not suitable for laying cable lines in them. Laying of cables without the middle in the ground is allowed when there are no more cables. The laying of cables in pipes laid in the ground is fenced in for the soil-permafrost and climatic minds. On the crossings with other cable lines, roads and underground cable utilities, they were later seized with gypsum concrete slabs.

Laying cables close to buildings is not allowed. The introduction of cables from the trench into the wake-up call at the time of the ventilated floor is guilty of the presence of a zero mark.

2. The laying of cables in the channels is allowed to be stored in places, and a large ball can be stored from non-minimal soils and a small surface with a burrow of no more than 0.2%, which will prevent the stick of surface waters. Cable ducts slid vykonuvati from water-impermeable to solid concrete and pokryvati zvni nadіynoі gіdroizolyatsіyu. At the top of the canal, it is necessary to close it with concrete slabs. The canals can be visibly bogged down into the ground and without bumping (on top of the ground). In the last drop of the canal and close to a new one is guilty of a Viconan pillow with a thickness of not less than 0.5 m from dry soil.

2.3.33. All middle cable lines can be laid without the middle on the construction of the cable lines (open and in ducts or pipes), near channels, blocks, tunnels, pipes, laid in downlogs and crossbars, as well as foundations of machines, in mines, cable lines.

2.3.34. Oil-filled cables can be laid (if there are any number of cables) in tunnels and galleries and in the ground (in trenches); the way їх laying of visas is initiated by the project.

2.3.65. With the installation and termination of power cables, the design of the couplings has been fixed, and it will help to guide the minds of their robots and the new middle ground. The knowledge and laying on the cable lines were to blame for the fact that the cables were stolen from the penetration of them in theology and in the many interesting speeches from the middle of the other

2.3.66. For cable lines up to 35 kV, the final and complete couplings are to be blamed on the basis of prior technical documentation on the couplings, which have been approved in accordance with the established procedure.

2.3.67. For full and retaining couplings of cable oil-refined lines, a low vice requires only brass or middle couplings.

Dovzhina sections and the process of installing stopper couplings on cable oil-refined lines of a low vice start with the use of oil lines in normal and transient thermal conditions.

Retaining and semi-retaining couplings on cable oil-refined lines are responsible for the installation in the cable wells; When laying cables in the ground, it is recommended to remove the muffs in the chambers, in order to prevent the onset of the prospect of the milieu of the earth anyway.

In areas with electrified transport (metropolitan, trams, zaliznytsia), or those that are aggressive in terms of wear to metal sheaths and couplings of cable liners with soil, the bottom couplings are guilty but are available for control.

2.3.68. On cable lines, which can be seen by cables with normally leaked papier insulating cables and cables leaked through non-leaking maso, the cables can be pulled through the extra stop-connecting couplings, when the cables are not leaking through the cables. . Also 2.3 .51).

2.3.69. On cable lines of 1 kV, you can see the dull cables with the humic insulation in the humic hose, the cables can be connected to the ground with hot volcanoes, covered with anti-high varnish.

2.3.70. The number of double-sided couplings per 1 km, which will be expected, of cable lines is probably not more: for three-core cables 1 10 kV with a cross-chain up to 3 x 95 mm2 4 pcs.; for three-core cables 1 10 kV with crossbars 3 x 120 - 3 x 240 mm 2.5 pcs.; for three-phase cables 20-35 kV 6 pcs.; for single-core cables 2 pcs.

For cable lines 110-220 kV, the number of boom couplings is based on the project.

Victory of small-scale cables for the installation of long cable lines is not allowed.

Zagalny vimogi

2.3.11. The design and construction of cable lines is carried out on the basis of technical and economic design for the development of the line, the attribution of the line, the nature of the route, the method of laying, the design of these cables.

2.3.12. When choosing the route of the cable line, it follows according to the possibility of a unique number of soils with agressive soils to metal sheaths of cables (div. Takozh 2.3.44).

2.3.13. Above the underground cable lines, according to the official rules for protecting electrical fences, the guilty is set up guard zones in the area of the maydan over the cables:

for cable lines of 1 kV, 1 m from the skin side from the extreme cables;

for cable lines up to 1 kV, 1 m from the skin side from the extreme cables, and with cable lines passed in places along the sidewalks - 0.6 m towards the sidewalk, and 1 m towards the other part of the street.

For underwater cable lines up to and including 1 kV, a security zone has been set up, as long as the rules are set, which should be parallel straight lines at 100 m from the extreme cables.

Protection zones and cable lines vikoristovyutsya according to the rules of protection of electrical fences.

2.3.14. The path of the cable line is guilty of vibrating with the least amount of vitality to the cable; When the cables are spaced apart, they are crossed between themselves, with pipelines and in.

With the vibration of the cable route, oil-improving lines, a low grip will be taken up to respect the balance of performance for the most rational distribution and performance on the line.

2.3.15. The cable lines are of such a rank, so that in the process of installation and operation, they include the identification of non-secure mechanical voltage and equipment, for which:

the cables are guilty but laid with a margin sufficient to compensate for the potential damage to the soil and temperature deformations of the cables themselves and their designs, behind the smell of laying; lay a supply of cable at the viglyadі kіlets (coils) fenced off;

cables, laid horizontally along the structures, stin, perekritiv, etc., are to blame for being tightly fastened in the end points, without the middle at the end of the refueling, on the offensive sides of the wiggles and at the bottom couplings;

cables, laid vertically along the structures and walls, are due to the fact that they were fastened so that the deformation of the sheaths was not damaged;

constructions that fit non-armored cables, due to such a rank, the possibility of mechanical sheathing of cable sheaths is included; in times of hard fastening of the sheath, the cables are responsible for the safety of mechanical devices and corrosion due to the addition of elastic gaskets;

cables (including reservations) mechanical engineering(Oversupply of vehicles, mechanisms and vantages, accessibility for third parties), guilty of being stolen by height at 2 m from the floor of the road, or by 0.3 m in the ground;

when the cables are laid, there is a line with other cables, which are in operation, if you are guilty, come in for the last time;

the cables must be laid on the surface of the heated surfaces, so that the heating of the cables is not tolerated, at the same time the transfer of the cables is to be guilty of.

2.3.16. The zahist of cable lines from flaky streams and ground corrosion is responsible for the satisfaction of the vimogs of the rules and SNiP 3-04.03-85 "Zakhist awesome constructions and with the help of corrosion "Derzhbudu Russia.

2.3.17. The constructions of underground cable systems are responsible for the protection of the mass of cables, soil, road coverage and support for transport.

2.3.18. Cable constructions and constructions, on which cables are laid, are to blame for non-combustible materials. Zaboronyaєnja vikonannya in the cable sporuds of be-like timchanovyh outbuildings, taking in them materials and ustatkuvannya. Timing cables are to be laid out of all possible connections, provided to cable laying, with the permission of the operating organization.

2.3.19. As a result, the laying of cable lines is to blame for the improvement of the middle stage of sleepiness, as well as the heat production of a kind of dzherel heat. If the cables are laid at geographic latitude at 65 °, it is not necessary to have a sleepy connection.

2.3.20. The radii of the internal crooked cables are due to the mother in terms of the multiplicity up to the first diameter, not less than those of the standards, or of the technical minds for the specific brands of cables.

2.3.21. The radii of the inner crooked vigin of the cables when the cable terminations are due to the mother, according to the ratio to the induced diameter of the veins, the multiplicity is not less than the values specified in the standards or technical intelligence for the type of cables.

2.3.22. Zusillya tension before the hour of laying the cables and stretching them in the pipes, but begin with mechanical stresses that are permissible for living and shells.

2.3.23. The skin cable line is guilty of the mother's number or the name. If the cable line is stored from decal parallel cables, then the leather is responsible for the same number from the letters A, B, B, etc. Kintsev couplings brands, springs, pererezu, numbers or namenuvannya line; on the tags of the back couplings - the number of the coupling and the date of installation. Birki are guilty, they are steady up to the inflow of a navkolishny middle. On cables laid near cable sporums, the guilty tags should be worn out by 50 m.

2.3.24. Protective zones and cable lines laid in the ground in unforgettable moments, are guilty of being signified by information signs. Information signs have not been installed any further after 500 m, and also in the shortest possible time there are cable lines. The information signs indicate the width of the security zones of the cable lines and the telephone numbers of the cable lines. (Marvel at the supplement "Vimoga to information signs and installation")

Vibir of ways of laying

2.3.25. When choosing methods of laying power cable lines up to 35 kV, it is necessary to step by step:

2. Laying of cables near tunnels, along walkways and in galleries is recommended when there are a number of power cables, going in one straight line, more than 20.

3. The laying of cables in blocks is stagnant in the minds of great density along the road, in times of flowing through the tracks and processes, when pouring metal, etc.

2.3.32. New types of cable laying in areas of deep permafrost can be carried out during the offensive:

Laying cables close to buildings is not allowed. The introduction of cables from the trench into the wake-up call at the time of the ventilated floor is guilty of the presence of a zero mark.

2.3.34. Oil-filled cables can be laid (if there are any number of cables) in tunnels and galleries and in the ground (in trenches); the way їх laying of visas is initiated by the project.

vibration cables

2.3.35. For cable lines, which are laid along the highways, which must pass in different soils and the minds of the midst of the middle, vibrating designs and overhanging the cables, then lead along the paths with the most important minds, like those who are not very light. With the significant increase in the number of track lengths with different minds, the gaskets for the skin of them should be vibrated by the appropriate design and the cable re-straining.

2.3.36. For cable lines, which are laid on the routes with the cold minds, the first time for the cable lines, the first ones vibrate along the route with the best minds of the cold, if it’s just about 10 m. If not more than three times for the drain, you should not be less than 20 m (div. also 2.3.70).

2.3.37. For cable lines, which are laid in the ground or water, it is the fault of the reservation of cables. The metal sheaths of the cables are to blame for the mother's harsh curvature for the protection of chemical injections. The cables with the latest constructions of the most recent pokrittіv (unarmored) due to the need for repairs to the mechanical injections when laid in all types of soils, when pulled in blocks and pipes, as well as due to the need for repairs

2.3.38. Pipelines of cable oil-refined lines in a high vice, which are laid in the ground or water, due to the cause of corrosion, according to the project.

2.3.39. It is recommended to lay unarmored cables in cable sporums and hardware devices when there are some problems with mechanical equipment in operation, and if there is a need for mechanical services in the operation of armor services.

Pose of cable spruce it is allowed to lay non-armored cables at an inaccessible height (not less than 2 m); On the smallest height, the laying of non-armored cables is allowed for wiping out of all kinds of mechanical items (boxes, coil steel, pipes, etc.).

In case of a change in laying (land is a cable sporud, or for a variety of applications), it is recommended to install quiet brands of cables, for laying in the ground (div. 2.3.37), altogether without combustible calls.

2.3.40. When laying cable lines in cable sporums, as well as in wired armored cables, they are not guilty of the mother over the armor, but non-armored cables - over the metal sheaths of the fixed curves from the combustible materials.

For open-circuit laying, it is not allowed to install power and control cables with combustible polyethylene insulation.

The metal sheaths of the cables and the metal surfaces, behind the strong stinks, are guilty of being stolen by non-combustible anti-corrosion coatings.

When laid in the middle with an aggressive middle ground, the blame for the cable stagnation, stiyky up to the inflow of the middle ground.

2.3.41. For cable lines of power stations, outbuildings and food stations, set in 2.3.76, it is recommended to secure cables, armored by steel stitch, stolen by non-combustible pokritty. At power stations, the storing of cables with fuel polyethylene insulation is not allowed.

2.3.42. For cable lines, which are laid in cable blocks and pipes, as a rule, they are guilty of storing unarmored cables from lead hardened cables. On the blocks of pipes and pipes, as well as from them up to 50 m, it is allowed to lay armored cables near lead or aluminum sheaths without cable sheathing. For cable lines, which are laid in pipes, it is allowed to fix cables from plastic or gumovy obolonts.

2.3.43. For laying in soils, for placing speeches, for ruinously running on the sheaths of cables (salt marshes, swamps, nasty runt with slag and awakening material, etc.) і with hardened curtains of types B, B or cables with aluminum sheaths; especially with hardened curtains of types B, B (in a suction vologous plastic hose).

2.3.44. In people who cross with cable lines, the cables are sore to the fault of geological minds, as well as chemical and mechanical fuses.

2.3.45. For laying in soils that are subdued until the end of the day, you should be guilty of storing the cables with ragged armor, or just get used to it, come on the cable when the ground is deformed (changing the row with grooved piles, like palm trees).

2.3.46. In the case of people, they have been rewound with cable lines, they have flooded and ditches, there are also cables, as for laying in the ground (div. Takozh 2.3.99).

2.3.47. For cable lines, which are laid on zaliznichny bridges, as well as behind other bridges with intensive traffic collapse, it is recommended to store armored cables in aluminum shells.

grounding

2.3.71. Cables with metal sheaths or armor, as well as cable structures, on which cables are laid, are guilty of being grounded or neutralized, as indicated in Ch. 1.7.

2.3.72. When grounded or neutralized metal sheaths of power cables, sheath and armor are guilty of being used by a nasty middle dart between themselves and from the body of the couplings (endsevikh, z'udnuvalnyh and in.). On cables 6 kV and vishche with aluminum sheaths, grounding sheaths and armor can be used by other conductors.

Zastosovuvati grounding or zero wired conductors from the conductor, more, less conduction of cable sheaths, is not necessary, however, the overflow in all types of cables is not less than 6 mm ².

The overhaul of the grounding conductors of the control cables after vibrating as long as 1.7.76-1.7.78.

On the basis of the construction, there is a plug-in coupling and a set of electrical connectors, then the armor, metal sheath and the coupling are attached to the grounding attachment of the electrical connectors. Vikoristannya in the strength of the grounding annex only the metal sheaths of the cables are not allowed in any kind of fall.

Estacadies and galleries to be guilty of being owned by the proprietor from the blisk of the rd 34.21.122-87

2.3.73. On the cable oil lines of the low vice, the ends, the bottom and the stop couplings are grounded.

On cables with aluminum sheaths, the attachments are fitted to the lines through the insulating inserts, and the housing of the end sleeves is made of the aluminum sheaths of the cables. It is intended that it does not extend to cable lines with no need to be inserted into the transformer.

In case of stagnation for cable oil-upgraded lines, the low grip of armored cables in the skin edge of the armor, the cable on both sides of the muff is guilty of being grounded.

2.3.74. The steel pipeline of oil-refined cable lines in a high vice, laid in the ground, is guilty of grounding at all wells and at the ends, and laying at cable spords - at the ends and in the intermediate points, by the design of the rosettes.

If it is necessary to actively clean up the steel pipeline due to corrosion, it must be grounded; electrical support anticorrosive coating.

2.3.75. During the transition of the cable line to the cable (PL) and at the exit from the support of the PL of the grounding cable attachment in the main cable sleeve (clutch), it is allowed to ground the cable attached to the metal sheath, which is the cable sleeve on the ground cable to the terminal 1.7.

Special vimogues to the cable government

2.3.76. Pay respect to the requests in 2.3.77-2.3.82, expand on the cable and power plants of the power supply of 25 MW and more, separate annexes and power stations, for the other 220-500 kV power plants, as well as Div. also 2.3.113).

2.3.77. The head diagram of the electric power plant, the diagram of the power requirements і the diagram of the operative strum, the control of the possession and the layout of the possession of the cable government of the electric power station, or the power station guilty of the viconuvatya such a rank, but in the case of the winners of the robots electrical stations, one hour at a loss, to back up the supply of power plants and power stations, as well as connections from robotic systems to detect and extinguish.

2.3.78. For the main cable streams, the power plants are responsible for the transmission of cable equipment (surfaces, tunnels, mines, etc.) technological possession and enable access to third-party cables.

When distributing cable streams at power stations, cable lines are guilty of the following:

to prevent overheating of cables from the heated surfaces of the technological installation;

zapobіgannya pozhkodzhen cables with vikhlop (sleepers and vibuhi) saw through zapobіzhny attachments of the pilesystems;

inadmissibility of the laying of transit cables in technological tunnels of hydraulic ash removal, in the vicinity of chemical water treatment, as well as in places where pipelines from chemically aggressive ridges are demolished.

2.3.79. Also reserve additional cable lines (power, operational line, connection, control, signalization, fire extinguishing systems, etc.) On the cable gates of the government, due to the failure of the emergency, I block the great development, the cable streams follow the delivery on the isolated one from the same group. Rozpodil cables in groups to be found in the deposits of the minds of the world.

2.3.80. In the boundaries of one power block, it is allowed to display cable spurs with a boundary fire rate of 0.25 years. With a whole technological possession, as you can serve as a fire-engine (tanks with oil, oil stations, etc.)

In the boundaries of one power unit of the power station, it is allowed to lay cables in the position of special cable equipment for cleverly fixing all the mechanical equipment and sawing, because of the speed of fire during the production of normal temperature control devices.

For securing access to the cables when rostaing them at a height of 5 m and more to blame for special maydans and go through.

For single cables and small groups of cables (up to 20), the operators may not be able to handle the cables, but at the same time, the possibility of quick replacement and repair of cables in the minds of the operator is safe.

At the time of laying the cables at the boundaries of one power unit, the position of special cable springs is guilty to ensure that it is possible to distribute them to some groups, so to pass along the small routes.

2.3.81. Cable surfaces and tunnels, in which the cables of the electric power stations are located, the cable surfaces and tunnels are connected to the control panels, which are responsible for being distributed over the blocks and through the tunnels on the top fires not less than 0.75 years, including in the passage of cables.

In the case of the transfer of cables through the partitions and the cross-section with the method of securing the possibility of replacing and pre-routing of cables, the partition is responsible for the transfer from the fire-resistant, it is easy to break through the changing material in the intervening fire resistance of 0.75 years.

In the long cable sporuds of thermal power stations, the blame for emergency transmissions, rosters, as a rule, does not go below 50 m.

The cables of the state power plant were responsible for the fact that they came out of the open-cut cable tunnels and collectors with fire-resistant partitions with an intermediate fire-resistance not less than 0.75 years.

2.3.82. The misconception of the cable entry into the attachment of the closed rosette annexes and the control of the control panels and the control of the subcritical rosette annexes are guilty of the mother of the partition with an intermediate fire resistance not less than 0.75 years.

It is not less than 0.75 years for the entrance of the cables to the blocks of the control panel of the power station.

The cable mines are guilty of being built from the cable tunnels, on top of and on the other cable tunnels with fire-resistant partitions with an intermediate fire-resistance not less than 0.75 years old, and the mothers have a crinkle in the mountains and at the bottom. When passing through the cross-section, the lengthy shafts do not go beyond 20 m, they go to the front with the fire-resistant partitions with the boundary fire-resistance not less than 0.75 years.

Passing cable shafts are responsible for the mother of the entrance doors and for the possession of the ratchets or special brackets.

Laying cable lines in the ground

2.3.83. When the cable lines are laid without the middle in the ground, the cables are to be laid in trenches and the mother from the bottom to the bottom, and from the top to the top of the earth with a ball, so as not to revenge the stones, wake-up wipe and slag.

Cables on all sides of the line were stolen from mechanical devices by a shielding path at a load of 35 kV and with galvanized concrete slabs with a thickness of at least 50 mm; at a voltage lower than 35 kV - with slabs or clay slabs in one ball across the cable route; for an hour the trenches of earth-moving machinery with a cutter width of less than 250 mm, as well as for one cable - bridging the cable line. Zastosuvannya silikatnoi, as well as clay hollow or widespread cegli are not allowed.

When laid on 1-1.2 m slots, 20 kV cables and lower ones (except for cables from the Moscow electrorezers), it is allowed not to seize from mechanical devices.

Cables up to 1 kV are responsible for such damage on dilenks, de imovirnі mechanical devices (for example, in parts of frequent openings). Asphalt pavement in the street і t. P. Looked like a mice, de rositta vyroblyayutsya in small vypadki. For cable lines up to 20 kV, small lines up to 1 kV, to live power supplies of the 1st category *, it is allowed in trenches with a number of cable lines no more than two to stop the replacement of the signal line, the plastic back It is not allowed to stop signal strikes in the places where the cable lines flow from the engineering companies and over the cable couplings on the stand, 2 m to the skin side from the cross-country communication lines, as well as on the road.

* Behind the minds of the mind, for the sake of the lord of the line, it is allowed to expand the area of the signal strikes.

The signal line is guilty to fit in the trench above the cables at the exit of 250 mm from the last curves. When rosetting one cable in the trench, the line must be laid along the axis of the cable, with a large number of cables - the edge of the line is guilty of sticking for the extreme cables not less than 50 mm. If more than one line is laid along the width of the trench, the sum of the lines should be laid with an overlap with a width of at least 50 mm.

When the signal lines are stuck, the laying of cables in the trench with the attachment of the cushions for the cables, the sticking of the cables with the first ball of earth and the laying of the lines, including the sticking of the lines with the ball of earth along all the way, due to the power of the electricity being carried out in the presence of the representative of the electrician.

2.3.84. The depth of the laying of cable lines from the planuval mark is not less to blame: lines up to 20 kV 0.7 m; 35 kV 1 m; when the street is overturned and the area is square, it is 1 m wide.

Cable oil-filled lines 110-220 kV are responsible for the depth of laying of planuval marks not less than 1.5 m.

It is allowed to change the gibini up to 0.5 m on dalyankas up to 5 m when introducing the glue into the wake-ups, and also in times to cross-over from the ground spores for clearing the cables from the mechanical devices (for example, laying in pipes).

The laying of 6-10 kV cable lines on other lands is to blame for a depth of at least 1 m, while the smog of the earth above the road can be occupied by the sea.

2.3.85. Stand at the prospect through a cable laid without the middle in the ground, up to the foundations of the building and with the equipment not less than 0.6 m. When transit cables are laid in the hallways and technical undergrounds of residential and community buildings, the keruvatis SNiP Derzhbudu Russia.

2.3.88. In case of parallel laid horizontal lines at the openings from cable lines up to 35 kV and oil-connected cable lines to pipelines, water supply, ducts and drainage, it is not less than 1 m; to gas pipelines of low (0.0049 MPa), medium (0.294 MPa) and high vise (from 0.294 to 0.588 MPa) - not less than 1 m; to gas pipelines in a high vice (from 0.588 to 1.176 MPa) - not less than 2 m; to heat conductors - see 2.3.89.

In the minds of the bounded expanse, it is allowed to change the values \ u200b \ u200bof the connections for cable lines up to 35 kV, for a vignette of connections to pipelines with combustible ridges and gases, up to 0.5 m without special cable routing and up to 0.25 m when the cables are laid. For oil-upgraded cable lines 110-220 kV on a distance of up to 50 m, it is allowed to change the line horizontally near the pipelines, due to the fault of pipelines with combustible moisture and gas pipes, up to 0.5 m behind , which is a great opportunity for mechanical devices. Parallel laying of cables over and under pipelines is not allowed.

2.3.89. When the cable line is laid in parallel with the heat conductor, there must be at least 2 m of heat conduction at the cable through the cable and the heat conduit in the heat conduit, or the heat conduction on all the connection between the cable line is due to the mother. Rocky without changing 10 ° С for cable lines up to 10 kV and 5 ° С - for lines 20-220 kV.

2.3.90. When the cable lines are laid in parallel with the gaps, the cables should be laid, as a rule, the posture of the road outside the zone. The laying of cables in the boundaries of the zone is allowed only for weather conditions with the organization of the Ministry of Highways, when the cable is installed up to the axis of the number of zones, it is not less than 3.25 m, and the road for electricity is not less than 3.25 m. The change in the values \ u200b \ u200bwithin the case of a whole cable for all the delay, the blame should be laid in blocks or pipes.

With electric roads on post-struma blocks or pipes, but they are insoluble (asbestos-cement, leaked tar or bitum too) *.

2.3.92. When a cable line is laid in parallel with motor roads of categories I and II (div. 2.5.145), the cables must be laid on the other side of the ditch, or if the ramp is placed on the sides of at least 1 m from the edge or not less than 1.5 m of the edge. The change in the designated appearance is allowed to appear in the skin condition due to weather conditions with the latest management of the roads.

2.3.93. When the cable line is laid in parallel from the 110 kV submarine, the cable goes up to the vertical area, so that it passes through the extreme wire of the line, guilty, but not less than 10 m.

Go to the wells from the cable line to the grounding parts and the grounding supports of the submarine at 1 kV, for reasons not less than 5 m at a load of up to 35 kV, 10 m at a load of 110 kV and at a load of 110 kV. In the minds of the open space, from the cable lines to the underground parts and grounding of the sub-line supports of 1 kV, no less than 2 m is allowed; when the cable goes up to the vertical area, it is not normal to pass through the submarine wire.

It is not less than 1 m, and if the cable is laid on a distance in an insulating pipe of 0.5 m, it must be at least 1 m to the support of a submarine up to 1 kV.

On the territory of the power plant and the power station in the minds of the adjacent space, it is allowed to lay cable lines on the walls of at least 0.5 m from the underground part of the supports of the external links (power lines) and grounding lines up to 1 kV

2.3.94 *. When the cable lines are overwhelmed by the stink, they are broken by a ball of earth with a size of not less than 0.5 m; as in the sinks of the space for cables up to 35 kV, it can be changed up to 0.15 m for the separation of cables for all lengths plus 1 m to the skin side with slabs or pipes for concrete or any equivalent material; with a whole cable, the connection is made to the power cables.

___________________

* It was pogodzheno with the Ministry of the Ministry of the USSR call of the USSR.

2.3.95. If the cable lines of pipelines, including naphtha and gas pipelines, are interrupted by cables and pipelines, they must not be less than 0.5 m. m to the skin side in pipes.

If the cable oil lines are overhauled, there is no less than 1 m of the line between them in the light.

2.3.96. When the heat conductors are overwhelmed by cable lines up to 35 kV, the heat conductors are connected to the cables and the heat conduits in the light are not less than 0.5 m, and not less than 0.25 m in the drains of the adjacent space. the side of the extreme cables is responsible for such heat insulation, so that the temperature of the earth did not increase by more than 10 ° С according to the average summer temperature and 15 ° С according to the average until the lower winter.

In vipadki, if it is not possible to hit the mark, it is allowed to visit one of the coming visits: cable gagging up to 0.5 m is 0.7 m (div. 2.3.84); zasosuvannya cable inserts large overflow; laying of cables with a heat conductor in pipes on the outside outside not less than 0.5 m, if the pipes were guilty, they were laid in such a rank, so that the cables could be replaced without a vison of earthlings robots (for example, the chamber was introduced to the end of pipes).

When the cable is connected to the oil line, the heating line goes between the cables and the heat line is not less than 1 m, and in the minds of the adjacent space - not less than 0.5 m. so heat insulation, so the temperature of the earth did not move more than 5 ° C at any hour of fate.

2.3.97. When the cable lines cross over to roadways, the cables must be laid in tunnels, blocks or pipes along all the widths of the zone and at least 1 m from the road bed and not less than 0.5 m from the bottom of the water channels. When the area is out of the way and when it’s significant, please, lay the guilt on the wall, plus 2 m along the sides of the road.

In case of overflowing cable lines, electrical and electrical power on the continuous flow *, the blocks and pipes are insoluble (div. 2.3.90). Miscellaneous is guilty of being at least 10 m from the side of the arms, the crossbars and the first to the strips of the cables. Peretin cables with paths of electrified rail transport are guiltyly carried out along the road at 75-90 ° to the axis of the number.

________________

* Good weather with the Ministry of the Nobles.

Kintsi blocks and pipes are guilty of being embedded in jute with braided cords, which were coated with waterproof (mint) clay for a depth of not less than 300 mm.

When the dead-end roads of industrial designation with little intensity of collapse, as well as special routes (for example, on slips, etc.)

When the route of cable lines is overhauled, it is not necessary to build up a lot of non-electrified cable lines by road or by car. At the misconception, they are guilty of pledging for the repair of cables in the necessary number of reserve blocks or pipes with completely clogged ends.

At the time of the transition of the cable line to the winding, the cable is guilty of going to the surface at the top of not less than 3.5 m from the bottom to the bottom or from the edge of the canvas.

2.3.98. When tram lines cross the cable lines, the cables should be laid in insoluble blocks or pipes (div. 2.3.90). Peretin can be seen on the back of not less than 3 m from the strips, the crossbars and the shortcut to the strips of the electric cables.

2.3.99. In case of overflowing cable lines for vehicles near the courtyard, garages, etc. Laying of cables is guilty of being carried out in pipes. In the same way, they are guilty of stolen cables in times of re-threading the gutters and ditches.

2.3.100. When installing cable sleeves on cable lines, stand at the light between the cable sleeve housing and the closest cable, but not less than 250 mm.

When laying cable lines on steep tracks, the installation of cable sleeves on them is not recommended. If necessary, the installation of cable sleeves on such dies is caused by the horizontal platform.

For securing the possibility of rewiring the couplings in case of installation on the cable line, it is necessary to lay the cable on the offensive sides of the couplings with a margin.

2.3.101. If the cable line of flaky strings of non-safe values is visible along the cable line, it is necessary:

1. Change the route of the cable line from the team, so that you can bypass the necessary zones.

2. In case of unhappiness of changing the track: go in before the maximum reduction of the level of the bloody strum; zasosuvati cables with an advanced stike up to the age of corrosion; zd_sniti active zakist of cables from inlet to electrocorrosion.

When laying cables in aggressive soils and zones with the appearance of flaky streams of unacceptable value, cathodic polarization is to blame (installation of electrical drainages, protectors, cathodic zapist). If there are any methods of connecting the electric drainage attachments, the guilt is determined by the norms of potential development on the windows of the construction, the transfer of SNiP 3.04.03-85 "The driver of the awakening Russian structures and equipment" Zastosovuvati cathode zakist zvnіshnіm strum on cables laid in saline soils or salinized waters is not recommended.

The need to obtain cable lines due to corrosion is due to the fact that the data obtained from electrical tests and chemical analyzes of soil samples are obtained. The zachist of cable lines due to corrosion is not to blame for the minds that are not safe for the robot and the earthly sector. Projected to come back in order to get a corrosion fault, but not before the introduction of the new cable line into operation. If there are flaky streams in the ground, it is necessary to install control points on the cable lines in the places and on the walls, so that it is possible to start between non-safe zones, which is necessary for a further improvement in vibration.

To control the potentials on the cable lines, it is allowed to drive the cables to the transformer station, etc.

Laying cable lines at cable blocks, pipes and concrete trays

2.3.102. For the preparation of cable blocks, as well as for laying cables in pipes, it is allowed to use steel, asbestos-cement, concrete, ceramic and similar pipes. When the material for blocks and pipes is vibrated, the level of groundwater and aggressiveness, as well as the appearance of bloody streams, should be shown.

Oil-filled single-phase cables of a low vice need to be laid only in asbestos-cement and magnetic pipes, in which case the skin phase is guilty of being laid in the vicinity of the pipes.

2.3.103. A number of channels in blocks are allowed, provided that there is a difference between them and the size of the fault is accepted until 1.3.20.

2.3.104. The skin cable unit is responsible for up to 15% of reserve channels, and not less than one channel.

2.3.105. The depth of laying in the ground of cable blocks and pipes is to blame for the misalignment of the sinks, but not less than the ones that were pointed at 2.3.84, and vazhayuyu to the upper cable. The depth of installation of cable blocks and pipes on supercritical areas and in the logs of viral applications is not standard.

2.3.106. The cable blocks are guilty of the mother and not less than 0.2% towards the wells. The same snag is necessary to take care of when laying pipes for cables.

2.3.107. When pipes are laid for cable lines without a middle ground in the ground, there are fewer pipes and between them and other cables and spores to be used, as for cables laid without pipes (div. 2.3.86).

When cable lines are laid in pipes in the ground, they are used, as for laying in the ground.

2.3.108. At missions, there is a direct route of cable lines, laid in blocks, and in places where cables and cable blocks go to the ground, it is due to the construction of cable wells, so that you do not have to hand-stretch the view of the cables. Such wells are responsible for the construction also on straight lines of the highway on one side of the road to the city, so that there is a borderline permissible heavy cables. With the number of cables up to 10 and no more than 35 kV, the transition of cables from blocks to the ground is allowed to go without cable wells. When the cables come out of the blocks, they must be embedded with waterproof material.

2.3.109. The transition of cable lines from blocks and pipes in the future, tunnels, walkers and so on. P. is responsible for one of such methods: without a priori inserted in them blocks and pipes, with a call for wells in a number of wells in all the middle chambers.

Guilty, but you must come in, so that you can penetrate through the pipes or open the water and other creatures from the trenches in the buds, tunnels, too

2.3.110. Channels of cable blocks, pipes, wiring from them, as well as the reason for the blame of the mother was scraped off and the surface was cleaned for securing the mechanical processing of cable sheaths when pulled. At the outlets of cables from blocks in the cable equipment and cameras, please go in, so that you can use the cables from the erasing and distribution (stopping the elastic pads, to see the necessary information)

2.3.111. at high rivn Ground waters on the territory of the ASU have led to overhead ways of laying cables (in trays or boxes). Above ground trays and slabs for the purpose of making use of the Viconan and the concrete. The trays are guilty of being laid on special concrete pads with a thickness of not less than 0.2% along the planned route in such a rank that does not overshadow the flow of spill water. With the appearance in the bottoms of the above-ground trays of bursts, it is not necessary to catch the release of angry waters.

If there are no cable trays for laying the cables, it is not possible to travel through the territory of the VRU and travel to the possession of machines and mechanisms that are necessary for the installation of repairs and operating robots. For the sake of being guilty, drive through the trays for additional concrete slabs with the help of the transport to pass through the trays, in order to save the installation of the trays on one level. If cable trays are stuck, it is not allowed to lay cables along roads and crossings in pipes, canals and trenches, laid out at the bottom of the trays.

The exit of the cables from the trays to the head of the management and the owner is guilty of vikonuvatisya in the pipes, so not to sink into the ground. The laying of cable jumpers in the boundaries of one center line of the GRP is allowed in a trench, moreover, it is not recommended for the installation of pipes for the seizure of cables when they are brought up to the control head and relay. The zahist of cables from mechanical machines is guilty of using other methods (from zasosuvannya kutochka, channel and іn.).

Laying of cable lines at cable sporuds

2.3.112. The cables are equipped with all types of cables, depending on the possibility of additional cable routing in the range of 15% of the number of cables transferred by the project (replacement of cables in the process of installation.

2.3.113. Cable surfaces, tunnels, galleries, houses, and mines are to blame for being built from other sources and susceptible cable with fire-proof partitions and cross-bars with inter-fire resistance not less than 0.75 years. With such partitions, the length of the tunnels are guilty of being distributed to no more than 150 m with the presence of power and control cables and no more than 100 m with the presence of oil-supplemented cables. The area of the skin of the subordinate stati is not more than 600 m2.

Doors in cable sporums and partitions with boundary fire resistance 0.75 years are at fault for mothers between fire resistances not less than 0.75 years in electrical installations re-insured at 2.3.76, and 0.6 hours in other electrical installations.

Going out of the cable systems, the guilty parties are referred to, for example, in the presence of the categories D and D. If the cable is not more than 25 m long, one view is allowed.

The cable doors are designed to be such that they are conceived with gabled porches. The door locks from the cable systems are due to the name of the mother's locks, the door locks from the cable systems are opened without a key, and the doors are sometimes due to the closest input that is available.

Passing cable lines and places with servicing places for the mother come in with drabins. The entrance is not more than 150 m from the entrances.

Come in by the mother of the door, so that you will gain free access to the restaurant for persons who will not be tied to the servants of the cable government. Doors are guilty of the mother, the locks are locked, so that they can be opened without a key from the inner side of the door.

The entrance to the cable gallery when laying 35 kV cables in these cables is not more than 150 m, and when laying oil-refined cables - not more than 120 m.

Renowned cable houses and galleries are guilty of the mother of the main non-technical building structures (colonies, beams) from aerated concrete with an intermediate fire resistance not less than 0.75 years, or from steel rolled with an intermediate fire resistance not less than 0.25 years.

Inadequate constructions are built, as they can be deformed not without fail, because I can reduce the mechanical performance in case of mountain groups (streams) of cables, laid close to these constructions on the newest cable paths and galleries, which are lost.

The cable galleries are responsible for the duration of the fire with anti-fire partitions with a boundary fire for at least 0.75 years. Dovzhina from galleries is to blame for not more than 150 m when cables up to 35 kV are laid in them and not more than 120 m when oil-advanced cables are laid. On the last cable galleries, close to the private area, the meaning of this can not be expanded.

2.3.114. In the tunnels and canals, you are guilty of drinking water and oil in them, and you are also guilty of protecting the water from the muddy waters. The mothers were guilty of them not less than 0.5% in the direction of water intake or evil canalization. Passing through one tunnel to the last one, when they were roasted in the winter, was to blame for the additional ramp with a 15 ° cut. Attach the steps between the tunnels to fence.

At the cable channels, where the position of the primitives and the growth of the groundwater level is built up, the bottom of the earth is allowed with a drainage area of 10-15 cm from the rammed gravel or squeak.

In the tunnels, they are responsible for the transfer of drainage mechanisms; At the same time, it is recommended to set the automatic start-up in the fallow area from the water level. Start-ups and electric motors are guilty of the mother's office, allowing them to work in especially great missions.

When crossing the road and gallery of the passable type with one sign on the road, the buti of the vikonaniy ramp with a slope of no more than 15 ° is guilty. Yak vynyatok, it is allowed to swipe down with a 1: 1 hook.

2.3.115. Cable ducts and sub-paths in rosette outbuildings and in the guilty ones are curved over with the use of large, fire-resistant slabs. In the electric machine and the other side of the canal, it is recommended to re-curl the corrugated steel, and in the control panels with parquet pidlogs - wood shields with parquet, stolen from the bottom with asbestos and asbestos blades. Reduction of channels and subordinate channels was guilty of being insured for oversubscription according to a new type of ownership.

2.3.116. The cable ducts were posed for the sake of being guilty, but they were squeezed over the upper plates with a ball of earth not less than 0.3 m. Masa okremoї pliti perekrittya, I know it by hand, is not guilty of perevischuvati 70 kg. Plates are guilty of the mother attached for the purpose.

2.3.117. On delinkas, there may be spills of metal melting, lines with a high temperature, or speech, ruinously on metal sheaths of cables, equipped with cable channels are not allowed. It is not allowed to attach hatches in the collectors and tunnels on the designated doors.

2.3.118. Underground tunnels pose as if to blame the mother on top of a ball of earth with a size of no less than 0.5 m.

2.3.119. With a spilly laid cables and heat conductors in sporums, additional heating is carried out by a heat conductor in the installation of cables in any hour, not to blame for the change of 5 ° C, for whom the heat must be transferred to the ventilation pipes.

1. Control cables and cables must be connected only above the power cables; at the same time, go through the partition. It is allowed to lay control cables and cables over and above the power cables in the case of overhanging and overhauling.

2. Control cables are allowed to lay a handrail with power cables up to 1 kV.

4. Some groups of cables: working and backup cables for 1 kV generators, transformers, etc.

5. Rozdіlovі partitions, designated in clauses 1, 3 and 4, are guilty of being in the fire with the boundary fire not less than 0.25 years.

In case of automatic fire-burning from the stove of the mechanical-mechanical signal or the poured water and the partitions, specified in clauses 1, 3 and 4, it is allowed not to get up.

At the last cable galleries and in the last closed private cable galleries, the installation of separate partitions, as specified in items 1, 3 and 4, is not required. At the same time, it is necessary to reserve the power cable lines (for a vignette of lines to the electric power supplies of a special group of the 1st category), then lay from the back of them not less than 600 mm; in the galleries along the sides along the aisle.

2.3.121. Oil-filled cables should be laid, as a rule, in some cable spores. It is allowed to lay separately with cables; at the same time, oil-filled cables have been removed in the lower part of the cable equipment and emerged from other cables with horizontal baffles with intermediate fire resistance not less than 0.75 years. With such partitions, one of the same oil-filled cable lines emerges.

2.3.122. The need for the registration of automatic stationary recordings and extinguishing in cable disputes must be made on the submission of documents that have been approved in accordance with the established procedure.

At a safe closeness to the entrance, hatches and ventilation shafts (in the radius not more than 25 m), fire valves were installed. For the fastest grocery and galleries, the guides are guilty of such a position, so that it was not 100 m from any point of the highway axis of the road to the nearest guide.

2.3.123. In cable sporuds, the laying of control cables and power cables with a 25 mm² and larger cross-section, for a win, non-armored cables with a lead sheath, slid viconuvati on cable structures (consoles).

Control unarmored cables, power unarmored cables with a lead sheath and unarmored power cables of all sizes with a 16 mm² overretch and less should be laid on trays or partitions (susilny or unsuccessful).

It is allowed to lay cables along the bottom of the channel if the depth is not more than 0.9 m; When a group of power cables is installed between a group of 1 kV power cables and a group of control cables must be at least 100 mm, or at least a group of cables must be separated by a non-paired partition with an intermediate fire rate of at least 0.25.

Vidstanі mіzh okremimy cables guided in the table. 2.3.1.

Plugging the power cables laid in the canals to get caught (vinyatok div. U 7.3.110).

2.3.126. Oil-filled cables of a low vice are guilty of being attached to metal structures in such a rank that the ability to install around cables in closed magnetic circuits is enabled; to be seen between the walls of the building, it is guilty that they are not more than 1 m.

Steel pipelines of cable oil-advanced lines in a high vice can be laid on supports or pidvishuvatisya on pidviskah; to be made up of supports, or on the basis of a project line. In addition, the pipelines are guilty of being fastened on untidy supports for stopping temperature deformations in pipelines in the minds of exploitation.

It is not the fault of the pipeline to be lifted off the support with the support from the pipeline to any changes or the ruin of the foundations of the supports. The number of significant supports and the number of times the project begins.

Mechanical support and support of the wall outlets on the lines of the high grip of the grip for the use of the openings of the pipes, the illumination of the closed magnetic circuits around them, and in the cases of the wall in front of the walls

2.3.127. The height of the cable wells is not less than 1.8 m; The height of the chambers is not normal. Cable wells for full, retaining and semi-retaining couplings are not suitable for mounting the couplings without rosette.

Shore wells on sub-water crossings are at fault for the mothers of construction, so that they will not be able to distribute reserve cables and switch devices.

At the bottom of the well, the pit is guilty for the collection of ground and spill waters; maє buty also transferred to the water supply lines up to the ones pointed at 2.3.114.

Cable wells are responsible for the safety of metal gates.

At cable wells, cables and pull-out couplings are guilty of storage on constructions, trays or partitions.

2.3.128. The hatches of cable wells and tunnels have a diameter of not less than 650 mm and are closed with mobile metal shields; Christians are guilty of their mothers attached to their nobles. The middle primacy of the storage of other krishka is not needed.

2.3.129. On the bottom couplings of power cables with a 6-35 kV other in tunnels, cable surfaces and channels, special housings have been installed for localization of fire and vibrations, which can be susceptible to malfunction during electrical breakdowns.

2.3.130. Kintsev mufti on cable oil-advanced lines of a high grip are guilty of roztashovuvatsya in the case of a plus temperature, either because of the possession of automatic heating at a lower temperature during the turn of the day below + 5 ° C.

2.3.131. When laying oil-filled cables in the galleries, it is necessary to transfer the scorched galleries up to the technical minds for oil-filled cables.

The use of oil-living units in the line of a high grip is responsible for natural ventilation. Pidzemnі pіdzhivlyuyut points are allowed along with cable wells; in the case of a large well, they will be provided with water-supply annexes until 2.3.127.

2.3.132. Cable springs, for a winyatkad, wells for back couplings, ducts and chambers, are responsible for the safety of natural or piece ventilation, and the ventilation of the skin is to blame for being independent.

The opening of the ventilation of cable ducts starts, when the temperature difference comes up and at night, it is not more than 10 ° C.

Ventilation annexes are provided with shutters (gates) to provide access to the fire in the event of a fire, as well as to freeze the tunnel during the winter hour. Viconannya of ventilation annexes can ensure the possibility of storing automatics for the accessibility of food in the equipment.

Once the cables are laid in the middle, it is the fault of the overheating of the cables due to the increase in the temperature of the daily turnover and the infusion of technological equipment.

Cable fittings, behind a vignette of wells for back couplings, canals, cameras and open circuits, are due to the possession of electrical illumination and a net for living portable lighting fixtures and tools. At thermal power stations, it is allowed not to visonuvati for living the tool.

2.3.133. The laying of cables at collectors, technological galleries and technological platforms is shown as per the SNiP Derzhbud of Russia.

When paralleling the paths and galleries with different lines, the connection between the cables and the wires, the connections and the radio signals from the cables, start on the way To provide a call and radio communication, you can move up and down above the parkways and galleries.

The name of the height of the cable network and the gallery in the non-building part of the territory of the industrial enterprise is responsible for the possibility of laying the lower row of cables at least 2.5 m of the plane mark of the earth.

Laying of cable lines in virobnykh applications

2.3.134. When cable lines are laid in virobnichnyh sites, the guilty parties are guilty of the following:

1. Cables are available for repair, and when laid out - for viewing.

Cables (including armored items), roztasovaniye in mіtsyah, de carried out the relocation of mechanisms, possession, vantage and transport, guilty of being stolen from a reason, according to information prior to the release, guided at 2.3.15.

2. View in the light between cables and see what is shown in the table. 2.3.1.

3. Stand between parallel power cables and pipelines of all kinds, which, as a rule, should not be less than 0.5 m, and between gas pipelines and pipelines with combustible ridges - not less than 1 m. from mechanical devices (metal pipes, casings, etc.) on the entire distance plus 0.5 m from the skin's side, and in necessary cases, stolen from overheating.

Peretinu with cables passing through the wall at a height of not less than 1.8 m from the path.

Parallel laying of cables over and under the mast-lines and pipelines with a combustible line at a vertical area is not allowed.

2.3.135. The laying of cables at the bottom and between the top crossbars is to be carried out in channels or pipes; laying cables in them tightly is not allowed. The passage of cables through the crosshairs and internal walls can be carried out in pipes or openings; When laying cables, gaps in pipes and openings are due to butt-laid, easily punched with non-removable material.

The laying of cables near the ventilation ducts shall be protected. It is allowed to overhaul the channels with single cables laid in steel pipes.

Invisible laying of the cable along the adjoining cells is not allowed.

Pidvodna laying of cable lines

2.3.136. In case of overflowing of cable lines, channels, channels, etc. The cables should be laid over the road on the rails behind the bottom and on the banks, with little power overflow (overflowing of lines - see 2.3.46). At the time of laying cables through rivers with an unstable channel and shores that were frail until they were broken, the cables were buried in the bottom, it was guilty that they were destroyed by the wounds of the minds of the world. Glibina laying of cables is a project. It is not recommended to lay cables in the areas of piers, berths, harbors, other ferries, as well as winter regular parking of ships and barges.

2.3.137. When cable lines are laid in the sea, they are guilty of data about the depth, fluidity and style of changing water in the transition, panel winds, profile and chemical bottom warehouse, chemical water warehouse.

2.3.138. The laying of cable lines is guilty of being carried out along the bottom in such a rank that the stench in the uneven mists did not smell on the vases; gstr_ vistupi povinn_ buti usunen. Milini, kam'yani ridges and іnshі pіdvodnі pereshkodi on the trail go around and pass trenches in them or go through.

2.3.139. When the cable lines flow through the rivers, channels and so on. The cables, as a rule, are guilty of sinking into the bottom to a depth of not less than 1 m on coastal and small-water ramps, as well as on ship-floating and floating roads; 2 m with overflowing cable oil lines.

At water bodies, bottom-sinking robots are carried out from time to time, the cables are sunk into the bottom to the mark, as they are assigned for the weather with the organization of water transport.

When laying cable oil-refining lines 110-220 kV on ship-floating rivers and channels with the aim of securing them from mechanical devices, it is recommended to fill the trenches with small mice with a small cape of stones.

2.3.140. Come up with cables, sink into the bottom of the rivulets, canals and so on. With a width of water up to 100 m, it is recommended to take at least 0.25 m. , calculated for the bagatory average water level.

When laid in the water cables in a low vice at a depth of 5-15 m, and in case of a fluid leak, which does not exceed 1 m / s, if there are some phases (without special drift of phases between oneself), it is recommended to take not less than 0.5 m, but not less than extreme cables of parallel lines - not less than 5 m.

With sub-water laying at a depth of 15 m, as well as with a flow rate of more than 1 m / s, in some phases and lines, it will be taken up to the project.

In case of parallel laid under water cable oil lines and lines up to 35 kV, the horizontal line is not less than 1.25 gb in the light, calculated for the average average water level of 20, but not less than not less.

Run horizontally from cables, sink into the bottom of the rivulets, channels and water, to pipelines (oil pipelines, gas pipelines, etc.) m. It is allowed to change the length of up to 15 m for the weather with the organization, at the previous ones, they overwhelm the cable lines and pipelines.

2.3.141. On the shores without well-built embankments in the underwater cable passageway, there is a transmission reserve of at least 10 m at a river and 30 m in case of a sea bridge, which can be easily accommodated. On the deepest embankments, cables must be laid in pipes. In the middle of the cable connection, as a rule, it is the fault of the cable wells. The upper end of the pipe is guilty of entering the coastal well, and the lower end of the pipe is not less than 1 m from the lowest level of water. On the coastal areas, pipes are guilty but they are not pledged.

2.3.142. In the middle of the river, where the channel is and take care of the dams until the rise, it is necessary to survive the entry against the bare cables during the ice drift and on the way to the change of the banks (paved, through the dams, piles, piles, plates, etc.).

2.3.143. Peretin kabel_v between himself under water to fence.

2.3.144. Underwater cable crossings are marked on the shores with signal signs according to the rules of navigation on internal ship-floating routes and sea channel.

2.3.145. When three or more cables are laid in water up to 35 kV, one backup cable is responsible for transmission to three working workers. When cable oil lines are laid in the water from single-phase cables, there is a reserve of transmission: for one line - one phase, for two lines - two phases, for three or more - for the project, but not less than two phases. The reserve phases were guilty of such a rank, so that the stench could replace any of the active working phases.

Laying cable lines for special sporums

2.3.146. The laying of cable lines on stone, concrete and metal bridges is to blame for the failure of the small bridge in the channels, or in the vicinity of the skin cable in the fire-resistant pipes; it is necessary to transfer the water to the drain of the evil waters through the pipes. It is recommended to lay in asbestos-cement pipes for metal and concrete bridges and when cables come up to them. When crossing from the bridge structure into the ground, it is recommended to lay cables in asbestos-cement pipes as well.

All underground cables when passing through metal and concrete bridges are electrically isolated from the metal parts of the bridge.

2.3.147. The laying of cable lines on wood structures (bridges, moorings, pirs, etc.)

2.3.148. At the time of the passage of cables through the temperature bridges and from the construction of bridges on the sidewall, please, go in for the winnings in the cables of mechanical devices.

2.3.149. The laying of cable lines on rowing, dams, piers and berths without the middle in an earthen trench is allowed when the ball of earth is not less than 1 m.

AREA OF STRAIGHTENED, VALUE

2.3.1. For more information, see the chapter of the Rules to extend to cable power lines up to 220 kV, as well as lines to be used with control cables. Cable lines are more and more vikonuyutsya for special projects. Dodatkovi vimogi to the cable lines in Ch. 7.3, 7.4 and 7.7.

2.3.2. A cable line is called a line for the transmission of electrical energy, but also for signals from the system, which can be stored from one or the same decile parallel cables from the additional, retaining and brake clutches (fastening) and the screws ...

2.3.3. Cable equipment is specifically designated for the distribution of cables, cable sleeves, as well as oil-living devices and equipment that are designed for normal robotic oil-refurbishing of cable lines. To cable sporod are carried out: cable tunnels, channels, ducts, blocks, shafts, overheads, subpages, cable sites, galleries, chambers, pidzhivlyut points.

The cable channel is called close and zagliblen (sometimes or raised) into the ground, pidlog, cross, etc. neprohіdne sporuda, intended for distribution in a new cable, laying, looking around and repairing which can be carried out only if you are not sure about it.

A cable mine is called a vertical cable sporud (as a rule, a straight-handed overhang), at any height in the clearing, a bit wider on the side, without brackets, or a drag for oversubbing some people (pass through mines).

A sub-basement is called an empty space, surrounded by walls of adjoining, between the upper sections and old slabs (on all or part of the area).

A cable block is a cable sporud with pipes (channels) for laying cables in them and being carried to the wells.

A cable junction is called overground or above ground, see horizontally, or stole a lengthy cable sporud. The cable rack can be either passable or not passable.

The cable gallery will be called above ground or above ground, close it up or down (for example, without bichny stin) horizontally or stole a lengthy cable spore.

ZAGALNІ VIMOGI

2.3.11. The design and construction of cable lines of fault is carried out on the basis of technical and economic design for the development of heights, the attribution of the line, the nature of the route, the method of laying, the construction of the cable.

2.3.12. When choosing the route of the cable line, it follows according to the possibility of a unique number of soils with soils that are aggressive in terms of wear to metal sheaths of cables (div. 2.3.44 ).

2.3.13. Above the underground cable lines, according to the official rules for protecting electrical fences, the guilty is set up guard zones in the area of the maydan over the cables:

for cable lines of 1 kV, 1 m from the skin side from the extreme cables;

For underwater cable lines up to and including 1 kV, a security zone has been set up, as long as the rules are set, which should be parallel straight lines at 100 m from the extreme cables.

Protection zones and cable lines vikoristovyutsya according to the rules of protection of electrical fences.

2.3.14. The path of the cable line is guilty of vibrating with the least amount of vitality to the cable; When the cables are spaced apart, they are crossed between themselves, with pipelines and in.

With the vibration of the cable route, oil-improving lines, a low grip will be taken up to respect the balance of performance for the most rational distribution and performance on the line.

2.3.15. The cable lines are of such a rank, so that in the process of installation and operation, they include the identification of non-secure mechanical voltage and equipment, for which:

cables, laid horizontally along the structures, walls, crossbars, etc., are guilty of being tightly fastened in the end points, without the middle at the end points, on the offensive sides of the twigs and at the rear and retaining couplings;

cables, laid vertically along the structures and walls, are due to the fact that they were fastened so that the deformation of the sheaths was not damaged;

cables (including armored items), roztasovanі in mіstsyah, where possible mechanic services (oversupply for vehicles, mechanizmіv and vantage, availability for third parties), guilty of being seized by the ground for 2 m earth;

when the cables are laid, there is a line with other cables, which are in operation, if you are guilty, come in for the last time;

the cables must be laid on the surface of the heated surfaces, so that the heating of the cables is not tolerated, at the same time the transfer of the cables is to be guilty of.

2.3.16. The driver of cable lines from flaky streams and ground corrosion is responsible for the satisfaction of the rules and SNiP 3.04.03-85 "The driver of alarm constructions and construction of corrosion" to the State of Russia.

Zaboronyaєnja vikonannya in the cable sporuds of be-like timchanovyh outbuildings, taking in them materials and ustatkuvannya. Timing cables are to be laid out of all possible connections, provided to cable laying, with the permission of the operating organization.

2.3.19. During the period of time, the laying of cable lines is to blame.

2.3.20. The radii of the internal crooked cables are due to the mother in terms of the multiplicity up to the first diameter, not less than those of the standards, or of the technical minds for the specific brands of cables.

2.3.21. The radii of the inner crooked vigin of the cables when the cable terminations are due to the mother, according to the ratio to the induced diameter of the veins, the multiplicity is not less than the values specified in the standards or technical intelligence for the type of cables.

2.3.22. Zusillya tension before the hour of laying the cables and stretching them in the pipes, but begin with mechanical stresses that are permissible for living and shells.

2.3.23. The skin cable line is guilty of the mother's number or the name. If the cable line is stored from parallel parallel cables, then the skin of them is guilty of the mother of the same number for the letters A, B, C, etc. When cables have been installed, as well as cable couplings are guilty of being protected with tags for the labels on the cables and end couplings of the brand, straps, reruns, numbers or the name of the line; on the tags of the back couplings - the number of the coupling and the date of installation. Birki are guilty, they are steady up to the inflow of a navkolishny middle. On cables laid near cable sporums, the guilty tags should be worn out by 50 m.

2.3.24. On the route of the cable line, laid in an unforgettable way, it was due to the fact that there were established signs. The route of the cable line, laid across the green lands, is guilty of but is marked by signs, which were established not less than 500 m, as well as in the places of the road.

VIBIR GASKET METHODS

2.3.25. When choosing methods of laying power cable lines up to 35 kV, it is necessary to step by step:

2. Laying of cables near tunnels, along walkways and in galleries is recommended when there are a number of power cables, going in one straight line, more than 20.

3. The laying of cables in blocks is stagnant in the minds of great density along the road, in times of flowing with large lines and processes, when pouring metal, etc.

2.3.26. On the territory of the power plant, the lines of responsibility are laid in tunnels, ducts, channels, blocks, along the paths and in galleries. The laying of power cables in trenches is allowed only to all other ancillary facilities (paliva warehouses, mains) with no more than six. On the territory of the power plant, with a pulling force of up to 25 MW, it is also allowed to lay cables in trenches.

2.3.27. On the territory of industrial enterprises, cable lines of guilt are laid into the ground (in trenches), tunnels, blocks, canals, along the walkways, in galleries and along the walls of the week.

2.3.28. On the territory of the production stations and the auxiliary attachments of the cable lines, the lines of responsibility are laid in tunnels, ducts, channels, pipes, in the ground (in trenches), above-ground concrete trays, along walkways and in galleries.

2.3.30. Along the streets and areas, filled with underground communes, the laying of cable lines in the number of 10 and more in the future, it is recommended to conduct in the collectors and cable tunnels. When the streets are overhauled and the area with good coverage and the intensive traffic collapse, the cable lines must be laid in blocks or pipes.

2.3.31. When equipped with cable lines in areas of frosty permafrost, there are physical phenomena associated with the nature of bagatorny permafrost: abysmal soil, frost troughs, frosts, etc. Falsely from the minds of the earth, cables can be laid into the ground (in trenches) below the deep ball, in a small ball in dry, kindly draining soils, in piece rags from large-skeletal dry free-standing soils, in trays on the surface of the earth. It is recommended to lay the cables spilly with pipelines for heating, water supply, canalization, etc. in special sporums (collectors).

2.3.32. New types of cable laying in areas of deep permafrost can be carried out during the offensive:

Laying cables close to buildings is not allowed. The introduction of cables from the trench into the wake-up call at the time of the ventilated floor is guilty of the presence of a zero mark.

2.3.33. All middle cable lines can be laid without the middle on the construction of the cable lines (open and in ducts or pipes), near channels, blocks, tunnels, pipes, laid in downlogs and crossbars, as well as foundations of machines, in mines, cable lines.

2.3.34. Oil-filled cables can be laid (if there are any number of cables) in tunnels and galleries and in the ground (in trenches); the way їх laying of visas is initiated by the project.

VIBIR cables

2.3.35. For cable lines, which are laid along the highways, which must pass in different soils and the minds of the midst of the middle, vibrating designs and overhanging the cables, then lead along the paths with the most important minds, like those who are not very light. With the significant increase in the number of track lengths with different minds, the gaskets for the skin of them should be vibrated by the appropriate design and the cable re-straining.

2.3.36. For cable lines, which are laid on the routes with the cold minds, the first time for the cable lines, the first ones vibrate along the route with the best minds of the cold, if it’s just about 10 m. ale not more than three for a drain, but for the least amount of time to become not less than 20 m (div. 2.3.70 ).

2.3.37. For cable lines, which are laid in the ground or water, it is the fault of the reservation of cables. The metal sheaths of the cables are to blame for the mother's harsh curvature for the protection of chemical injections. The cables with the latest constructions of the lasting pokrittiv (non-armored) are due to the need to be repaired before mechanical injections when laid in all types of soils, when pulled in blocks and pipes, as well as additional costs.

2.3.75. During the transition of the cable line to the cable (PL) and at the exit from the support of the PL of the grounding cable attachment in the main cable sleeve (clutch), it is allowed to ground the cable attached to the metal sheath, which is the cable sleeve on the ground cable to the terminal 1.7.

SPECIAL VIMOGI TO THE CABLE GOVERNMENT ELECTRIC STATION

2.3.76. Pay your respects to the 2.3.77-2.3.82 , Expanding on cables of the state heating and hydroelectric power plants with a capacity of 25 MW and more, separate annexes and power stations with a 220 - 500 kV power supply, 2.3.113 ).

2.3.77. The head diagram of the electric power plant, the diagram of the power consumption і the diagram of the operational strum, the control of the possession and the layout of the possession of the cable government of the power station, for the power station to be guilty of such a rank, so that the state is in charge of the winners of the robots , one hour at a time, in addition to reserve the supply of electrical annexes and power stations, as well as connections to robotic systems for detecting and extinguishing.

2.3.78. For the main cable streams of power plants, the transfer of cable equipment (surfaces, tunnels, mines, etc.), is isolated from the technological possession and access to the cables of third-party systems.

When distributing cable streams at power stations, cable lines are guilty of the following:

to prevent overheating of cables from the heated surfaces of the technological installation;

zapobіgannya pozhkodzhen cables with vikhlop (sleepers and vibuhi) saw through zapobіzhny attachments of the pilesystems;

2.3.79. Also reserve additional cable lines (power, operational line, connection, control, signalization, fire extinguishing systems, etc.) On the cable gates of the government, due to the failure of the emergency, I block the great development, the cable streams follow the delivery on the isolated one from the same group. Rozpodil cables in groups to be found in the deposits of the minds of the world.

2.3.80. In the boundaries of one power block, it is allowed to display cable spurs with a boundary fire rate of 0.25 years. With a whole technological possession, as you can serve as a fuel oil tank, oil stations, etc.

For securing access to the cables when rostaing them at a height of 5 m and more to blame for special maydans and go through.

2.3.81. Cable surfaces and tunnels, in which the cables of the electric power stations are located, the cable surfaces and tunnels are connected to the control panels, which are responsible for being distributed over the blocks and through the tunnels on the top fires not less than 0.75 years, including in the passage of cables.

In the long cable sporuds of thermal power stations, the blame for emergency transmissions, rosters, as a rule, does not go below 50 m.

2.3.82. The misconception of cable entry in the vicinity of the closed rosette annexes and in the subdivision of the control panels and the originator of the subcritical rosette annexes are guilty of the mother of the partition with an intermediate fire rate of no less than 0.75 years.

It is not less than 0.75 years for the entrance of the cables to the blocks of the control panel of the power plant to be closed with partitions with the boundary fire.

Passing cable shafts are responsible for the mother of the entrance doors and for the possession of the ratchets or special brackets.

LAYING OF CABLE LINES AT THE EARTH

2.3.83. When the cable lines are laid without the middle in the ground, the cables are to be laid in trenches and the mother from the bottom to the bottom, and from the top to the top of the earth with a ball, so as not to revenge the stones, wake-up wipe and slag.

When laid on 1 - 1.2 m cables, 20 kV and lower cables (except for cables from the Moscow electrorezers), it is allowed not to seize from mechanical devices.

Cables up to 1 kV are responsible for such damage on dilenks, de imovirnі mechanical devices (for example, in parts of frequent openings). Asphalt pavement, etc. it looks like a miscellaneous, de rozrittya vyroblyayutsya in іdkіsnyh vypadki. For cable lines up to 20 kV, small lines of 1 kV, it is allowed to live power supplies of the 1st category * are allowed in trenches with a number of cable lines no more than two to stop replacing the signal lines, plastic backsides It is not allowed to stop signal strikes in the places where the cable lines are connected to the communication lines from the engineering communities and over the cable couplings on the stand, 2 m to the skin side from the cross-country communication lines to the mufti, as well as on the road

* Behind the minds of the mind, for the sake of the lord of the line, it is allowed to expand the area of the signal strikes.

2.3.84. The depth of the laying of cable lines from the planuval mark is not less to blame: lines up to 20 kV 0.7 m; 35 kV 1 m; when the street is overturned and the area is square, it is 1 m wide.

Cable oil-filled lines 110 - 220 kV are responsible for the depth of laying of planuval marks not less than 1.5 m.

The laying of cable lines 6 - 10 kV on other lands is to blame for the depth of not less than 1 m, while the smog of the earth above the road can be occupied by the land.

2.3.85. Stand at the prospect through a cable laid without the middle in the ground, up to the foundations of the building and with the equipment not less than 0.6 m. When transit cables are laid in the hallways and technical undergrounds of residential and community buildings, the keruvatis SNiP Derzhbudu Russia.

2.3.86. In case of parallel laying of cable lines, the horizontal lines are not less than between the holes and the cables:

1) 100 mm between power cables up to 10 kV, as well as between them and control cables;

2) 250 mm between cables 20 - 35 kV and between them and other cables;

3) 500 mm * mіzh cables, exploited іznіznіy organizatsіyami, as well as mіzh power cables and cables;

4) 500 mm between oil-filled cables 110 - 220 kV and other cables: with a whole cable oil-filled lines of a low vice, one of the same and one type of cables is lifted with reinforced concrete slabs, placed on the edge; In addition, it is necessary to carry out the connection of the electro-magnetic inlet on the cable.

Allowed in all cases of need for weather and exploiting organizations for the urahuvannya of the minds of the change of places, as defined in paragraphs. 2 and 3, up to 100 mm, and between power cables up to 10 kV and interconnection cables, except for cables with flanges, impaired high-frequency telephone intercom systems, up to 250 mm for clearing the cables from the box, you can see if there is a shortage one of the cables (laying in pipes, installing concave partitions, etc.).

Inspection cables are not standardized.

2.3.87. When cable lines are laid in the nasadzhen zone, the pipes must be laid out to the stubbury trees, as a rule, not less than 2 m. ...

PIDVODNA LAYING OF CABLE LINES

23.136. In case of overflowing cable lines, streaks, channels, etc. the cables should be laid out on the dilenks behind the bottom and on the shores, which are not very strong. 2.3.46 ). At the time of laying cables through rivers with an unstable channel and shores that were frail until they were broken, the cables were buried in the bottom, it was guilty that they were destroyed by the wounds of the minds of the world. Glibina laying of cables is a project. It is not recommended to lay cables in the areas of piers, berths, harbors, other ferries, as well as winter regular parking of ships and barges.

23.137. When cable lines are laid in the sea, they are guilty of data about the depth, fluidity and style of changing water in the transition, panel winds, profile and chemical bottom warehouse, chemical water warehouse.

When laid in the water cables in a low vice at a depth of 5 - 15 m extreme cables of parallel lines - not less than 5 m.

With sub-water laying at a depth of 15 m, as well as with a flow rate of more than 1 m / s, in some phases and lines, it will be taken up to the project.

Run horizontally from the cables, sink into the bottom of the rivulets, channels and water, to pipelines (oil pipelines, gas pipelines, etc.) m. It is allowed to change the length of up to 15 m for the weather with the organization, at the previous ones, they overwhelm the cable lines and pipelines.

23.141. On the shores without well-built embankments in the underwater cable passageway, there is a transmission reserve of at least 10 m at a river and 30 m in case of a sea bridge, which can be easily accommodated. On the deepest embankments, cables must be laid in pipes. In the middle of the cable connection, as a rule, it is the fault of the cable wells. The upper end of the pipe is guilty of entering the coastal well, and the lower end of the pipe is not less than 1 m from the lowest level of water. On the coastal areas, pipes are guilty but they are not pledged.

When cable oil lines are laid in the water from single-phase cables, there is a reserve of transmission: for one line - one phase, for two lines - two phases, for three and more - according to the project; more than two phases. The reserve phases were guilty of such a rank, so that the stench could replace any of the active working phases.

LAYING OF CABLE LINES ON SPECIAL SPORUD

2.3.146. The laying of cable lines on stone, concrete and metal bridges is to blame for the failure of the small bridge in the channels, or in the vicinity of the skin cable in the fire-resistant pipes; it is necessary to transfer the water to the drain of the evil waters through the pipes. It is recommended to lay in asbestos-cement pipes for metal and concrete bridges and when cables come up to them. When crossing from the bridge structure into the ground, it is recommended to lay cables in asbestos-cement pipes as well.

A sub-basement is called an empty space, surrounded by walls of adjoining, between the upper sections and old slabs (on all or part of the area).

A cable block is a cable sporud with pipes (channels) for laying cables in them and being carried to the wells.

A cable junction is called overground or above ground, see horizontally, or stole a lengthy cable sporud. The cable rack can be either passable or not passable.

The cable gallery will be called above ground or above ground, close it up or down (for example, without bichny stin) horizontally or stole a lengthy cable spore.

2.3.4. To be called a box - see. 2.1.10 .

2.3.5. To be called a tray - see. 2.1.11 .

2.3.6. The cable oil-supplemented line of a low or high grip is called a line, in any trivial hour the permissible excess grip becomes:

0.0245 - 0.294 MPa (0.25 - 3.0 kgf / cm 2) for cables in a low vice in lead sheaths;

0.0245 - 0.49 MPa (0.25 - 5.0 kgf / cm 2) for cables in a low vice in aluminum shell;

1.08 - 1.57 MPa (11 - 16 kgf / cm 2) for cables in a high vice.

2.3.7. The section of the cable oil-advanced line of the low vice is called the line between the stop couplings or the stop and end couplings.

2.3.9. Rozgaluzhuvalny attachment is called a part of the cable line in a high vice between a steel pipeline and a single-phase clutch.

2.3.13. Above the underground cable lines, according to the official rules for protecting electrical fences, the guilty is set up guard zones in the area of the maydan over the cables:

For cable lines 1 kV, 1 m from the skin side from the extreme cables;

For cable lines up to 1 kV, 1 m from the skin side from the extreme cables, and with cable lines passed in places along the sidewalks - 0.6 m towards the sidewalk, and 1 m towards the other part of the street.

For underwater cable lines up to and including 1 kV, a security zone has been set up, as long as the rules are set, which should be parallel straight lines at 100 m from the extreme cables.

Protection zones and cable lines vikoristovyutsya according to the rules of protection of electrical fences.

With the vibration of the cable route, oil-improving lines, a low grip will be taken up to respect the balance of performance for the most rational distribution and performance on the line.

2.3.15. The cable lines are of such a rank, so that in the process of installation and operation, they include the identification of non-secure mechanical voltage and equipment, for which:

The cables are guilty but laid with a margin sufficient to compensate for the potential damage to the soil and temperature deformations of the cables themselves and their designs, behind the stench of the laying; lay a supply of cable at the viglyadі kіlets (coils) fenced off;

Cables, laid horizontally along the structures, walls, crossbars, etc., are guilty of being tightly fastened in the end points, without the middle at the end of the filling, on the side of the wiggles and at the rear and stop couplings;

Cables, laid vertically along the structures and walls, are due to the fact that they were fastened so that the deformation of the sheaths was not damaged and they did not break because they were still alive in the couplings before the power cables;

Constructions, on which unarmored cables are laid, are guilty of such a rank, but the possibility of mechanical processing of cable sheaths is included; in times of hard fastening of the sheath, the cables are responsible for the safety of mechanical devices and corrosion due to the addition of elastic gaskets;

Cables (including armored vehicles), roztasovanі in mіstsyah, de mozlivі mechanіchnіchnі pozhkozhdennya (oversupply of vehicles, mechanizmіv and vantazhіv, accessibility for third parties), guilty of being seized by the earth for 2 m earth;

Once the cables have been laid out with other cables, if they are in operation, please come in for the last time;

The cables must be laid on the back of the heated surfaces, so that the heating of the cables is not tolerated, at the same time the transmission of the cables is to be guilty of.

2.3.16. The zachist of cable lines from flaky streams and ground corrosion is guilty of the satisfaction of vimogs of the Tsikh Rules and SNiP 3.04.03-85"The excitement of alarm constructions and construction of corrosion" Derzhbudu Russia.

2.3.17. The constructions of underground cable systems are responsible for the protection of the mass of cables, soil, road coverage and support for transport.
