This is ensured by the triple extrusion using single (common) crosshead extrusion technique and Drycure inert gas cured cross linking process.The cables are manufactured and tested in accordance with IS: 7098 or BS: 60502.

Conductor : The conductors are made from electrolytic grade aluminium or copper wires and are stranded together and compacted.

Insulation : High quality XLPE compounds of natural colour are used for insulation. Insulation is applied by the Triple extrution Process and is chemically crosslinked in continous vulcanizing process.

Shielding : XLPE Cables rated above 3.3 kV are provided with both conductor shielding and insulation shielding, consisting of extruded semi-conducting compound. Additionally, insulation shield is provided with metallic tape shield over the extruded semi conducting shield.

Core Identification : Cores are generally identified by running a numbered tape or colour tape along the insulated core below the metallic shield

Inner Sheath : In case of multicore cables, cores are laid together with suitable fillers in the interstices and provided with a common tape covering. Alternatively, an extruded inner sheath is provided.

Armouring : Armouring is applied over the inner sheath and it normally comprises flat steel strips for multicore cables. Alternatively, round steel wire armouring can also be offered. Single core armoured cables are provided with non-magnetic armour consisting of hard drawn round aluminium wires.

Outer Sheathing : A tough outer sheath of heat resistant PVC Compound as per IS: 5831 is extruded over the armouring in case of armoured cables, or over the inner sheath in case of unarmoured cables. The outer sheath is usually black in colour for maximum resistance to outdoor exposure.
