RECOMMENDATIONS FOR INSTALLATION The following are some of the salient factors which should be kept in view during installation of PVC Insulated Heavy Duty Cables: 1. Before laying.

11 RECOMMENDATIONS FOR INSTALLATION The following are some of the salient factors which should be kept in view during installation of PVC Insulated Heavy Duty Cables: 1. Before laying. the insulation of the cable should be checked with megger as preliminary check against any probable damage. 2. ;The drum should be -always rolled in the "direction af arraw far rolling". ~arked an the drum. In the absence of any such mark. the drum should be rolled in the direction same as that of inside end of the cable and opposite to. that of the outside end..' 3. Where the cable is.to be jointed with existing cable. the sequence of cores at the two. ends to. be jointed should be in the opposite directlon. i.e. if at one end it is in clockwise direction, at the ather end it should be in anticlackwise dtrection. This is necessary to. avoid the crossing of cares while jointing. This will also. decide the direction in which the cable is to. be pulled. ' 4. Wherever possible bending radius of 12 times the overall diameter of the cable should be maintained. 5. Where the cables are necessarily laid and jointed in very cold regions. both the cable and the ambient temperatures should be above OOCand have remained so. far the previous 24 hours. During such condttlons, the cable should also not be bent to.very small radius. This is due to. the reason that atvery law temperatures PVC compounds became stiff and brittle. and are likely to. crack and shatter when stuck hard or bent to. small.redlus. 6. A joint being the weakest paint of the electric power transmisston system. all necessary precautions should be taken. Jainting materials and accessortes.itke conductor ferrules. solder, insulating and protective. tapes. protective filling compound, joint baxes. etc., of right quality and sizes should be procured. The applicatian of these materials should be. made skilfully far the' jointing work. In this connection. it is always advisable that the method and the working instructions.ot the supplier should be strictly followed. 7. Armoured cables: All bonding clamps at the joints and terminations and the armour wires should be thoroughly cleaned. The clamps should be adequately tightened. This is necessary to. ensure proper electricl contact. because armour is the only return path far earth fault current., ' II Unarmoured cables: In case of unarmoured cables. the external metallic earth banding connector of adequate size should be used. ' 8. Earth: All joints. terminations, armour wires, and external metallic bonding should be connected to. earth. Wherever possible, armour at one end Of the cable should be connected to main earth system at the supplying end by employing metallic connectors, ~). Precautions should be taken to. eliminate the chemical and bimetallic corro sion of the earth connector ar bands. 9. Filling compounds: a. The design of the box and the composttlon of the filling compound should. provide an effective sealing against entry of moisture to. conductorferrules and armour connectors, b. If hat pauring protective compounds are used. the temperature of the compound while pouring should not exceed 150 C. '- 10 Test after installation: After the cable is installed. D.C. voltage test may be carried aut. Each core should be tested at 3 Kv against others and the armour, the latters connected to. earth. The voltage should be increased gradually to. full value and maintained continuously far 15 minutes. No.breakdown of Insulation should occur during test. 22
