6.4. Labels should be fixed: for dry applications - made of plastic; in the orphans, the posture of buds and in the ground is made of plastic; on cables made of insulation from cross-linked polyethylene - from non-magnetic materials. The designation on the tags of the underground cables should be stamped, cored, or plucked. In RP, TP, PS, the designation is allowed to be applied with farboi, which does not sag.
The tags are guilty but fastened on the cables with a kapron thread or galvanized steel rod with a diameter of 1-2 mm or with a plastic string with a button. The place of fastening the tags on the cable with a dart and the self-drіt at the other locations (RP, TP, PS) and the land is covered with bitumen from the vlogs.
In the near slopes near the CS near the ground, lead tags are fixed at the good couplings, which are secured with a middle dart.
On a cable with insulation made of a sewn polyethylene tag, it is recommended to fasten with kapron, plastic threads or with a wire made of non-magnetic metals (for example, from midi).
6.5. The COP adopted the designation (write) on the tags:
At end couplings and mortgages - straight (name), nominal voltage, brand and pereriz KL;
For good couplings (near the ground) - the nominal voltage of the cable, the number of the mufti and the first letter name the district (South - Pivdenny district, N - Nevsky toshcho);
At successful muffs at canals, wells and tunnels - straight ahead (naming) that inscription, like a subterranean mufti;
On cables at channels, wells, tunnels, at subpills of RP and SS, at places where cables are laid at trenches and cable lines, at places passing through intersections and partitions - straight (name), nominal voltage, brand and cable span. The name of the electrical installation organization may be indicated on the tags at the couplings and the mortgage, installed by the electrical installation organizations.

In times of impossibility to bypass the area with soils, how to avenge the speech, how to ruin the cable shells (salt marshes, swamps, bulky soil with slag and budding scum, rot, fungus, etc.), as well as zones with it is necessary to block the cables with increased resistance to corrosion. |
| Swamp | The cables are to be selected according to the improvement of geological minds, as well as chemical and mechanical injections. |
| Grunty | It is to blame for the installation of cables with quarry armor, or to live in when you put in the zusil, so you can run on the cable when the soil is fixed (to replace the soil with sheet piles or palm spores, then). |
Tiporozmіri cap
1.1. Caps for sealing cable ends are selected after the dimensions, depending on the outer diameter of the cable, which is transferred to install the cap. It is necessary to vicorate caps with an adhesive (adhesive) warehouse, apply to the inner surface of the cap, or with special tabs for adhesive material.
1.2. For sealing ends of cables with insulation over cross-linked polyethylene, it is recommended to use caps from Raychem with reinforced indentations 102L (with hot melt adhesive), point at table 1.7.
Table 1.5
1.3. It is allowed to vikoristovuvat capi, prepared in a suitable way to technical minds TU 16 K71-051-89 "Kintsev cable heat shrinkage".
Rozmіri kap (kіntsevyh kіtsevyh kіtsevyh kabelnymi teplosadzhuvanih) with an adhesive liner (pokrittami) middle, prepared for given technical minds, induced in table 2.6.
Table 2.5
1.4. Due to weather conditions, the cable is allowed to be twisted with other caps, equal to the quality and dimensions.
Cap installation technology
2.1. Vimiryati dozhina of the cylindrical part of the kapi.
2.2. On the sheathed cable with a winding view of the tip, moving the length of the cylindrical part of the capi by 15-20 mm, indicating between the installation of the capi.
2.3. For the presence of ribs on the sheathed cable, take out the ribs on the installation site of the capi along the entire stake.
2.4. Clean the surface of the shell in the place of installation of the capi with a scouring pad and degrease with acetone (it is allowed to use aviation gasoline, oil or white spirit).
2.5. Take a mouth guard that matches the diameter of the cable sheath without ribs, and put it on the end of the cable (a glue ball is to blame between the cap and the sheath of the cable).
2.6. Light half-lights of the gas burner lay down the cap, starting from the butt (when the cap is heated, the shrinkage on the free sheath of the cable is to blame for the adhesive warehouse near the visible roller).
2.7. Date to cool down the installation to a temperature lower than plus 350C; until reaching be-yakі mekhanіchі dії at the place of installation are not allowed.
Replacement of a badly worn capi
To replace a worn capi, you need to:
3.1. take an ushkodzhenu kapa;
3.2. clean the surface of the shell near the zone of the cut cap with a scouring pad;
3.3. degrease the surface of the shell with acetone (it is allowed to use aviation gasoline, oil or white spirit);
3.4. take a cap that matches the actual diameter of the shell to the cable and mount it on the end of the cable for the technology introduced in the distribution of the 2nd addendum.
The acceptance of cable lines into operation is the final stage of work for installation. After the work is completed, if the power cable and the back couplings are no longer available for a direct look, the cable lines will be taken only in the process of electrical testing. It is not possible to detect defects in the laid line using the scientific methods of electrical testing. Therefore, the reliability of the robotic cable line in operation
take care less in that case, as if the line was ordered, the rules for laying and installing couplings were not violated.
The laying of the power cable according to the design, which is accepted for operation, is due to the minds of the minds of the most common medium and the accepted method of laying. Uninterrupted operation for an hour of operation of the cable line with a significant world to lie in the correctly selected type and brand of the laid cable.
Acceptance of disputes by a cable line route before laying power cables in them. On the cob, the laying of cables near the underground spores will ensure the completion of all everyday work. When accepting the budding part of the underground spores, they distort: the correctness of the distribution of the underground spores, the presence of their tricks for draining water, for example. it is necessary, electrical lighting, water pumping and ventilation, the water supply of the project, the supply of gas and water, as well as the installation of reinforced concrete structures. In addition, from the project, there is a lack of underground communication in third-party underground communications, and the correctness of the method of their interfacing with cable spores, for example, in additional pipes-cases, as well as the presence of thermal insulation for heat conductors. The correctness of laying the pipes of the block sewerage system is checked by a path stretching the metal of the cylinder with a diameter that is 5 mm smaller than the inner diameter of the pipes that are being changed.
The signs of the hatches of the wells are re-verified (as if the signs are fully covered, the passages are not guilty, the signs are larger than the lower by 1 cm), the presence of locking caps, embedded parts for fixing the cable under the hour of laying the cable. At the prozhdzhiy part of the chavun, hatches are laid down but laid on the lining of the reinforced concrete pillar.
Checking the viability of the robot at the laying process, it is necessary to lay the cable at the designated depth of cable laying, allowable radii of the guinea, penetration into the soil of the cavities, to lay out the sheaths of the cables, to stand between the cables at the light (not less than 100 mm), to stand on the crossbars and close to the power cable that is being laid, zaliznichnymi tram pipes, cables zv'yazku and іn.; the presence of a sleeping bed for a cable and cushions, zahisnih covers, reserves of a cable in front of the couplings to compensate for damage and weak reinforcement of the couplings in swampy and weak soils. Particularly often blamed are mechanical faults on cables for an hour of stretching them at pipes through the streets, as well as for an hour of introduction into the wake. Control over the strict requirements of the technology for the installation of couplings to change the twisting of the twisted twisted cores, the expansion of their fittings, the thickness of the winding of the insulation, the quality of the soldering, as well as the quality of the mounting material, the quality of the cable set, the tool that annex.

Just as the project on the cable line was transferred to the electric protection of the metal sheaths of the cable against corrosion, then when putting the line into operation, protocols may be transferred, which confirm the correctness of the operation of the protection of the anti-corrosion devices.
Before switching on, a cable line is laid, the minimum amount of starting testing is laid, which means that the conductors of the cable have a designated integrity, the insulation support between the conductors of the cable and between the conductors and the ground, at the test cable new lines of high elastic straightened strum and re-wiring installed on the lines of outbuildings of anti-corrosion protection of strum . At once, the correctness of the lineage was checked in phases from both ends of the line independently from the current congestion.

After the completion of all routine and installation work, the cable line is delivered to the building. Depending on the SNiP, the acceptance into operation of the new lacework may be carried out under the acceptance of the electric merging after the presentation of the completed spore in full with the technical documentation from the side of the deputy, yakim є mіskrada, ministries, okremi departments and organizations that represent them. In case of a defective cable line due to defects in cable laying and installation of couplings, the fault of the buditel-assembly organization for the supply of electricity may have the right to submit a complaint to the replacement for a stretch of 3 years from the moment the cable line is received ї in operation. The repair of the cable line in this case is to be blamed for the efforts, with the help of that for the work of the buditel-assembly organization, because of the blame for the failure of the line due to the defect it made in the robot.
To take the lines and її disputes into operation, a commission is organized, to which representatives of the deputy, the assembly organization and operation, including the person who supervises the robots, are included. Priymannya budіvelnih spores of cable lines to go through with the participation of a budіvelnik specialist. The representative of the zamovnika submits that technical documentation is transferred to the undertaking of the electric power supply, the translation of which was induced more.
The acceptance certificate is issued after the adoption of the budivel-assembly organization of all the committees that have been identified for short periods of time and the preparation of the line before the inclusion.
In the act, they say:
the name of the organization, which viroblyal sporudzhennya that installation of cable lines, the name of the virobniki and the representative of the exploitation, which zdiisnyuvav technical vision;
naming and recognition of the line and space of the gasket; short characteristic of the line (brand of the cable, cut, voltage, type of suitable and end sleeves, their number and number);
the relevance of the vykonan line to the project and the visnovok about the applicability of the line for operation.
At the time of putting the cable line into operation, the personnel of the electric power supply, on their own side, draw up the following technical documentation:
cable line passport. Zrazkovyy in place of the passport of the cable line with a voltage of up to 35 kV is induced at the addendum 16 Instructions for the operation of power cable lines [L. 3];
Inventory plan of the cable line route, warehouses on the basis of high-quality documentation and drawings on the exact topographical plan of space in a scale of 1:500 or 1:200, fallow in the plan with airborne cable lines and electric lines.
For Zruchnost, the bristles of the Colds, the Viberian Vimiruvan that rose ilongers of the Inszhenerenny Zavdan on the topographic plan of the trash of the cable lines are deprived of the calls of the Conturi Budіel, the Yaki є post -nye oriynters. Cable lines, their muftis and spores are “attached” to these buds (Fig. 1).
The route of the laid cable is applied to the inventory plan with the greatest possible accuracy and detailing of the line of the vzdovzh contours in the main streets of the street, the passage on the road, which corresponds to the scale of the plan. As a rule, cable lines and other organizations are not shown in the inventory plans of the routes of cable lines for the supply of electricity. Skin cable line, laid in the ground in improved sewerage - blocks, channels, collectors are displayed with their mental designations (color) in the fallage in the form of voltage and recognition of the line (life-giving line with a voltage of 6-10-35 kV, rozpodilna tension line 6-10 to the line voltage up to 1000). The recommended mental designation of cable lines and their spores is shown in fig. 2.

The inventory plan of the cable line will sound on the armchair paper with tablets of 500 X 500 mm 2 in size. For work in the minds of the floor, copies of inventory plans are put in place, like they are drawn on linen calcium or light copies.
The operation of cable lines is impossible without proper inventory plans for cable lines and a well-maintained technical archive. Plans are to be blamed for the improvement on the level of modernity with the help of systematic and timely application of current changes on them, refurbishment of the cable and couplings, which are called repairs, reconstruction and capital construction of the network. Technical archives are compiled from archive folders on the skin line. All documentation is taken from the right skin cable line (acts, factory protocols for testing the cable, protocols for expanding the gaps, and other.). Documents are placed in chronological order of their occurrence.
After the acceptance of the cable line by the operating personnel, the following preparations for the inclusion of the line of work are carried out:
the most admissible rozrahunkov strums are being installed for the purpose of traveling with the greatest thermal minds;
a new cable line is given a dispatch number or a name.
The tags from the dispatcher number assigned to the name are displayed on both end connections at the separate outbuildings (CPU, RP and TP), between which the line is laid. On the tags, it is indicated that the line is also cut.
For the safety of the minds of the dispatcher management and the integrity of the operation, it is necessary to observe the following principles of cable marking:
the tag at the skin end sleeve is responsible for indicating a separate attachment to the living center (CP), a separate point (RP), a transformer substation (TP) or a possession, whichever cable is laid and delivered. In this order, the names of the cable lines in the measure are distinguished by two numbers, or by the names of separate outbuildings, between which the cable is laid, or by switching equipment, to which cable is connected with its end couplings.
Since two and more cable lines were laid between the separate outbuildings, then the skin of them is supposed to have the same number with the addition of letters A, B, C, etc.;
if a cable line enters and exits at an intermediate branch extension, where one bolt is installed without stopping the switching equipment, then the name of the cable may also include the number of the intermediate switchgear;
life-giving cable lines that enter the switchgear of transformer points without blocking the switching equipment are assigned the number of the first (head) transformer point (TP), to which the line enters.
With the upgrade of the assigned dispatcher number, the necessary changes are made to the inventory plans of the cable lines, the operational diagrams of the electrical installations of the dispatcher boards in the district, the plot, the tablets of the schemes of the operational teams, as well as the technical passports of the various outbuildings of the city. Prior to switching on the line voltage, the operating personnel will carry out the following additional testing of the cable line: checking the integrity of the strum-conducting cores; phasing lived behind the phases; vibrating an upstretched, straightened struma; mitigation of bloating streaks, rechecking of installed anti-corrosion protections (for evidence); vimir earthing support. For cables with a voltage of 3-10 kV, testing is carried out six times, and for cables of 20-30 kV - five times the value of the nominal voltage of the cable. Trivality of testing the skin phase 10 min.
For cables with a voltage of 20-35 kV, additional preparations are made:
a) the designation of the active support for the direct struma lived, as a rule, according to GOST 340-59, but not more than 0.0184 ohm (per 1 mm 2 of the cut, 1 m of length at a temperature of +20 ° C) for the cable with the mid-wire and not more than 0.031 for cables with aluminum core;
b) the designation of the electrical working capacity of the conductors. Vimiryan єmnіst, induced to petty values, can be adjusted according to the results of factory testing more than 5%.
In electrical installations with a voltage of more than 1,000 with small streaks, ground flickering (500 A and lower) is more acceptable, the value of the support of the grounding outbuilding in the period of the least conductivity

In case of inconsistency, or due to sumnivnіv at the station of isolation and other data, a new cable line can be tested for a special expanded program for the participation of the laboratory for the supply of electricity. With positive results, the testing of a new cable line should be installed from one side under the working voltage, and behind the auxiliary phase installation, the phases of the cable should be checked for the bus bar and the connection.
After the re-verification of the same phases under the voltage, a new cable line can be put into operation and switched on under the voltage.
The commissioning of cable lines is carried out after the completion of the work on the laying of cables and the installation of suitable and termination couplings. All works must be completed until approved and approved by the project, the instructions of the Derzhbud SRSR for laying cables with a voltage of up to 110 kV (SN 85 - 74) and ceremonial technical documentation for sleeves for cables with paper and plastic insulation yu.
Cable lines, when taken into operation, are subject to inspection and electrical testing. Cables of attached laying (at trenches, blocks, too thinly) cannot be looked back after completion of all work on the routes, and the main methods of electrical testing do not allow revealing all defects in the laying of the line. Therefore, in order to ensure a good quality of work, it is necessary to control the laying of the cable and the installation of the couplings under the hour of їkh virobnitstv, so that you can get a technical look.
To enter technically at a glance: re-verification of cable spores and trenches; knowledge of the factory protocols for testing the cable and yoga camp; reverification of the capacity of the robot for the hour of cable laying and installation of couplings; control over the attendance of the installation personnel on the basis of which they allow the appointed work to be done. Yogo zdіysnyuє that organization, yak exploitation of cable laying.
Trenches, channels, tunnels and other cable spores are designed to meet the minimum allowable radii and twisted cables, pointing at the table. 16.
Table 16
Note. DK is the actual diameter of the cable.
When looking at the cable spores, the faults are reversed: the presence of devices for water drainage, electrical lighting, ventilation and water pumping; - adequacy of internal rozmіrіv to the project, steel of concrete structures and other.
Checking the capacity of the robot during the laying of the cable includes: control of the dynamometer for the tension of the cable; designation of allowable radiuses of bends, laying depths and between lines laid in parallel with cables, as well as between extreme cables and walls of spores; vyznachennya v_dstaney on peretina and zblizhennyah cables with different spores; control over the presence of the food pillow under the cable, zahisnih covers, cable reserves in front of the couplings, marking tags.
Control over the installation of the couplings includes re-verification: presence of conditional and non-stitched (term of appurtenance) component materials; the presence of a viable tool and attachments; dotrimanny obov'yazkovoї tekhnologii and sequencing installation.
On the marking labels indicate the brand, the nominal voltage, the number of wires, the number or the name of the cable line. On the tags of successful couplings of power cables, in addition, indicate the date of installation and the name of the electrician-cable; and on the tags of the end seals - endpoints (stars and where the cable is laid).
Cables after laying, installation of cable couplings and end seals, installation of end seals (into the cable entry of the Republic of Uzbekistan and others) must be tested according to the standards, the transfer of PUE. At the same time, with tests, the conductors are checked according to the phases of both ends of the line independently from the current congestion: the PUE has established the order of dividing the phases of the switchgear busbars. Phase L \ of tires turns into a yellow color, phase Lg - greens, phase L3 - red, and the zero operating bus N - black color, insulation of cable lines lived - behind the colors of tires, such stinks come.
After switching on the cable line under the voltage, the phases are reversed with the help of the accessories, as if the cable and the connected bus lived at the same phases. If the voltage difference between the residential cable and the same phase of the RU bus is equal to zero, it means the phases are different, if it is not equal to zero, it means the phases are not correct and the cable is incorrectly connected. Including such a cable in the backbone circuit can cause a short flicker. For phasing cable lines with a voltage of 6 and 10 kV, install voltage indicators of 10 kV in the kit with an additional support (Fig. 112).

Documentation for the building of cable lines in operation. The technical documentation includes a project of a cable line with changes, steps and introductions, with which, if the stench is good.
On the plan of the cable line, laid in the trenches, there are: coordinates of good couplings, tying to the main permanent houses or special recognition signs; scheme of the cable line from the assigned factory numbers of the drums for laying cables and their length; the sequence of laying drums and the numbering of successful couplings when laying cables near the trench; materials for the weather, run the cable line. In addition, actions should be taken: priymannya trenches and cable spores for installation; on prikhovani work from laying pipes; I will look at the cables on the drums before laying and protocols of their factory testing; I will look around the cable sewers in trenches and channels before closing; magazines for laying cables and processing cable couplings with a voltage of 1000 V, as well as protocols for heating cables on drums before laying at low temperatures and testing power cables after installation is completed.
All the necessary acts and protocols should be entered in the official record, as at the same time from the documentation they are presented at the hour of the task. The acceptance of the cable line into operation is carried out according to the act.
