SPECIAL INSTRUCTION AND ERECTION CONDITIONS FOR AERIAL BUNCHED CABLE.

1. GENERAL.
This section describes the rolling out and erection of bunched aerial cables. The instructions apply to bunched aerial cables with a maximum cross sectional area of 4X95 mm. If the cable is rolled out in different way from that described here, for example, manually or using a vehicle, other parts of the instruction still apply. 2 REQUIREMENTS.

The gang would normally consist of two erectors, at least one of whom must be familiar with these instructions. The Ganger or Foreman should obtain these instructions and a map in advance. A Work Plan should be made containing information relating to:
Storage size for the cable drums

Road Crossings. Other Obstacles. Angle Poles. Suspension and dead end poles. Duration of supply interruptions. Precaution to be taken near other lines, etc. Length of the pulling rope. Load Limits of tools and other equipments. If lookouts are required when crossing roads or other Obstacles, the size of the gang may have to be increased. When crossing busy roads, the help of the police or Road Traffic authorities should be sought. Poles should be fitted with fixtures for bunched aerial cables, as well as the necessary stays and down leads. The cable drums should be transported out and located according to the work plan.
3 ERECTION DATA.

TRIPURA STATE ELECTRICITY CORPORATION LTD

(A Govt. of Tripura Undertaking)

R-APDRP (Phase-II) L= Length of Line. N= Number of new aerial and earth cable service lines. N1= Number of existing service lines. The time required or installation may be calculated as follows. For cross sectional area 25 sq-mm, M = 22.6 L+2.1 N. For cross sectional area 50-95 sqmm. M = 26.1 L+ 2.1 N. Additional points when extending an existing installation.

Scope.
Further points to consider when working on existing low voltage networks are discussion with customers, extra notification of times when the supply will be interrupted , checks and breaks, as well as obstacles in the form of existing line, etc.
4 PREPARATIONS.

When a cable drum is used, it should be placed on drum jack or a carriage with a braking mechanism. Where necessary; the area where the drum is located should be roped off or guarded by personnel. Winches for extending the bunched aerial cable should be set up in advance at appropriate places. Warning signs should be set up at cross roads In accordance with local traffic regulations and any instructions that may have been issued. Where necessary, special safety measures should be taken. Radio equipment should be tested before work is started. The Pulling rope, which should be made of Synthetic fibre material, should be laid out manually along the path, the cable is to take. Rolling-out blocks should be set out if this has not already been done when erecting the poles. Rolling out blocks need not be set up where Suspension devices, which allow the bunched Aerial cables, to be pulled through are used. In the case of inner angles of 60 or more, a double Rolling out block should be used. In the case of outer angles, a rolling - out block with concave rollers, or a similar device, should be used. Note: - When rolling out bunched aerial cable with a cross sectional area greater than 50 sq-mm, a rolling out block with an extra wide cable wheel should be used on the pole nearest to the coil or cable drum. All equipments used must be suitable for the bunched aerial cable actually being used and for the force which arise during installation. 57

TRIPURA STATE ELECTRICITY CORPORATION LTD

(A Govt. of Tripura Undertaking)

R-APDRP (Phase-II)
5 ROLLING OUT.

The conductors of the bunched aerial cable should be alternately cut back about 100 mm in accordance with the diagram. The Pulling rope should then be stretched out the fixed in place with tape or nylon thread. The cable sock should be able to run through the rolling out blocks and suspension devices. To avoid wastage when jointing the cable, cable drums should be located on site in such a way that cable can be fed out from the new drum in one operation. Bunched aerial cable which is to be jointed should be pulled out in the same direction so that the phase relationship is correct.

When rolling out bunched aerial cable, the winch operator should be in radio contact with the supervisory personnel along the route. After the bunched aerial cable has been rolled out along its route, it should be fastened at the top of the last pole with a dead end clamp. If it is to be continued from this point, either as a service line or is to be connected to another line, provision should be made for this point determining its length.
6. TENSIONING.

The bunched aerial cable should be tensioned with a cable which located at the site of the cable drum until the approximate amount of sag between the poles has been obtained. For this purpose, the winch line should be fixed to the bunched aerial cable within the aid of a comealong Clamp.
7. FINAL TENSIONING.

When applying final tension to the bunched aerial cable, a lever winch and come-along clamp should be used. The tension force should be measured by using a Dynamometer, connected between the lever winch and come-along clamp on the bunched aerial cable. 58

TRIPURA STATE ELECTRICITY CORPORATION LTD

(A Govt. of Tripura Undertaking)

R-APDRP (Phase-II) Alternatively, the sag can be regulated by using a sight Rod. Sag and Tension data can be found in the tables. The bunched aerial cables should not be cut until tensioning is complete. Care should be taken to see that tools and ments are not overloaded during tensioning.
8. ERECTION.

equip-

End Pole:When the bunched aerial cable has been tensioned, it should be fastened by a dead end clamp and hook. The winch and lever which may then be slackened off and taken down. In line poles:The bunched aerial cable should be pulled through a suspension clamp and any rolling out block used then removed. Angle pole, Tension Poles & Lifting Poles :In the case of angle poles and poles with large vertical Loads, as well as lifting poles, come along clamps should be located on the bunched aerial cable about 1(one) meter on each side of the pole. A lever winch should be connected between the clamps, and the tension from the cable at the pole. The suspension clamps and dead end clamps can then be fitted.Works should be carried out from the rear of the post.
9. CONNECTION.

Bunched aerial cable to bunched aerial cable. Where a straight through joint is required, clamp should be attached about 1 meter on each side of the junction point so that the tension can be removed from the cable by the use of a lever winch and the cores separated. Alternatively, the cores can be separated by using wedges. 59

TRIPURA STATE ELECTRICITY CORPORATION LTD

(A Govt. of Tripura Undertaking)

R-APDRP (Phase-II) The cores should be stripped for screwed or clamped joints with a displacement of about 100 mm. The neutral joint should always be furthest from the pole. Stripping should preferably be done using a textile cutting string and not a knife. The jointing of the conductors should be done in accordance with the instructions detailed herein after under title ELECTRICAL CONNECTIONS. Bunched aerial cable to earth cable. Connections should be made along the lines of bunched aerial cable to bunched aerial cable. The earth cable should be stripped and the screen braided and insulated. Extra Insulation should be applied to the insulated cores. Insulation should be done either with insulating sleeves or insulating tape as set out herein after under title ELECTRICAL CONNECTIONS. Bunched aerial cable to earthing conductor. The earthing conductor should be connected to neutral conductor in the system in the same way as when connecting bunched aerial cable to bunched aerial cable. Bunched aerial cable to overhead wire:Bunched aerial cable can be located high up or below down the poles of an overhead wire transmission system and fixed as at an end pole. The conductors should be connected to the conductors of the overhead wire system using screw clamps. The cores of the bunched aerial cable should be taped together at the branch points. Bunched aerial cable to service entry:The Bunched aerial cables should be fixed to the building by clamps attached to a hook. The hook can either screwed in or take the form of a through- going bolt. The part of the building to which the bunched aerial cable is fixed must be strong enough to withstand the forces applied to it by the cable. The strands of the bunched aerial cable should be joined to the bushing conductors in accordance with the instructions set out herein after under title ELECTRICAL CONNECTIONS. 60

R-APDRP (Phase-II)
10. ELECTRICAL CONNECTION.

General:-. Conductors can be connected by screwing or clamping. However for joints which are under tensile stress, clamps connections are always required and these should be made in accordance with the instructions herein after under Title JOINTING. When using screw type connector, the torque applied to the screws should not exceed that for which the connectors are designed. In order to avoid clamping damage, spacers should be placed between the cores where necessary. In the case of pre insulated cramping sleeves, an inspection should be made to see that the insulation has not been damaged through the application of pressure. Clamps and crimping sleeves must be designed to suit the material in the conductors and should be mounted in such a way that galvanic currents do not cause corrosion. Care should be taken to see that copper conductors are not clamped over aluminum conductors. The Insulation of connections:Connections (Joint and junctions) on bunched aerial cable which are not pre insulated must be insulated so that they have the same dielectric strength as the conductors in the bunched aerial cables. The Insulation should be continued at least 20 mm beyond the ends of the joint and can be made with, - four layers of approved black insulating tape with 50% overlapping. -An insulating sleeve of black PVC which is well fixed at the ends with two layers of approved black insulating tape with 50% overlapping. -A cover of black insulating material. Before insulating crimped joints with tape, all sharp edges or burrs should be filed off, and any grease thoroughly removed.
11. JOINTING.

Joints under Tensile stress. Item -1: The two ends of the bunched aerial cable should be cut to an even length. Item -2:The cores should be cut as set out in the table below. CUTTING OF THE CORES USE Neutral Phase-I Phase-II Phase-III At the one end 0mm 300mm 600mm 900mm At the other end. 900mm 600mm 300mm 0mm 61

TRIPURA STATE ELECTRICITY CORPORATION LTD

(A Govt. of Tripura Undertaking)

R-APDRP (Phase-II) Measuring and cutting should be carried out with the greatest accuracy so that the mechanical stress is divided equally between the cores after cutting. Item 3: The cable cores should be stripped to half the length of the jointing sleeve. Stripping must not damage the conductors and should if possible, be carried out using textile cutting string. If a knife is used, the ends of the core insulating should be stripped off as if sharpening a pencil. Item-4: After placing a jointing sleeve on a conductor, the requisite number of crimping operations should be carried out starting at the centre of the jointing sleeve. Crimping should be done alternately from opposite sides of the sleeves in order to prevent the sleeve becoming bent. The corresponding conductor from the other cable end should then be inserted in the jointing sleeve and crimping fast. Item -5: Sharp edges or burns on the jointing sleeve should be filed or scraped off and all grease removed whetherupon the sleeve should be insulated as mentioned in ELECTRICAL CONNECTIONS. Take care that the lay of the cores is maintained. 12. TOOLS AND EQUIPMENTS:
