The following points should be kept in view during installation and testing of cables:
- Before laying, the insulation of the cable should be checked with a megger as a preliminary check against any transit damage.
- The drum should always be rolled in the direction of "arrow for rolling" marked on the drum. In the absence of any such mark, the drum should be rolled in the same direction as that of inside end of the cable and opposite to that of the outside end.
- Where the cable is to be joined with existing cable, the sequence of cores at the two ends to be joined should be in the opposite direction, i.e., if at one end it is in clockwise direction then it should be in anticlockwise direction at the other end. This is necessary to avoid the crossing of cores while jointing. This will also decide the direction in which the cable is to be pulled.
During installation of PVC/XLPE insulated heavy duty cables of 1100 V grade, bending radius should not be less than:
- Single core cables: 15 times the overall diameter of cable.
- Multi core cables: 12 times the overall diameter of cable.
- When the cables are laid and joined in very cold regions both the cable and ambient temperatures should be above 0° C and should have remained so for the previous 24 hours. During such conditions the cable should not be bent to very small radius. This is because at very low temperatures PVC compounds become stiff and brittle and likely to crack and shatter when struck hard or bent to small radius.
- Since a joint is the weakest point of the electric power transmission system all jointing materials and accessories like conductor ferrules, solder, insulating and protective tapes, protective filling compound, joint boxes, etc., should be of right quality and sizes for making the joint and working instructions of the supplier should be followed.
- Armoured Cables. All bonding clamps at the joint terminations and the armour wires should be thoroughly cleaned. The clamps should be adequately tightened. This is necessary to ensure proper electrical contact because armour acts as the return path for Earth fault current.
- Unarmoured Cables. In case of unarmoured cables the external metallic Earth bonding connector used should be of adequate size.
- 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 conductors.
- Filling Compounds.
- The design of the box and the composition of the filling compound should provide an effective sealing against entry of moisture to conductor ferrules and armour connectors.
- If hot pouring protective compounds are used, the temperature of the compound while pouring should not exceed 150° C.
- Proper Drum Handling
Protect cables from weather:
- Moisture is essentially injurious to wood. When stored outdoors, reels/drums tend to get wet and cultivate deteriorating fungus growths. Reels/drums should be kept off the ground so that moisture may not harm the cable reel flanges and laggings. Sound reels are easier to handle and there is less chance of injury to the cable as it is removed from the reel.
- All sites chosen for storage of cable drums should have well drained, hard-packed soil or preferably concrete surface which do not cause the drum to sink, lead to flange rot and extreme difficulty in moving the drums.

Everest brand LT PVC/XLPE Cables are of excellent quality and easy to handle. Simplified terminators and jointing techniques make these cables eminently suitable, among other applications, for industrial and mining installation. The main advantages of PVC Cables can be summarized as follows:
- Insulation resistance and breakdown strength are practically unaffected by moisture. These cables are thus suitable for laying even underwater.
- Can be overloaded for short periods without any appreciable effect on cable life.
- Can be laid vertically and on steep slopes as there is no impregnating compound involved.
- Flame retardant since PVC ignites with great difficulty and is self-extinguishing.
- Immune to chemicals normally encountered in practice.
- Due to their light weight, PVC cables are easy to install and handle. Small bending radius permits the termination of these cables in limited space.
- Low tension PVC cables do not normally require sealing ends, when terminated indoor. The terminations can therefore be effected quickly and economically.
- Tough but smooth outer covering and are thus abrasion proof.
- PVC cables are not affected by vibrations.
- PVC cables have high short circuit capacity since they can withstand a high transient temperature without any deformation of insulation or displacement of conductor.
- PVC cables have a long service life.
General Construction
Conductor
The conductor is composed of plain copper / aluminium wires complying with IS: 8130-1984. Mining cables used in gassy mines are of copper conductor only.
Insulation
The conductors are insulated with suitably compounded PVC / XLPE which is applied to the conductor by extrusion process.
These cables can also be offered with FRLS and Heat Resistant Properties.
