PVC Insulated Telecommunication Cables


We offer top class PVC Insulated Telecommunication Cables best suitable for telecommunication connection, EPABX or PBX system. Our specially developed PVC Insulated Telecommunication Cables are best used on DC battery systems. The PVC Insulated Telecommunication Cables offered by us contains apt insulation enables the user for 70oC continuous operation. Our PVC Insulated Telecommunication Cables are tightly lapped with a PVC tape and applied with an overlap of 30%. The color of the sheath in single pair and in case of Unarmored Multi paired of our PVC Insulated Telecommunication Cables is grey, but in case of armored cables it is available in black color.

Conductor :
The conductor is annealed, tinned electrolytic high conductive copper wire. The conductor is always used in solid condition.

Insulation :
The PVC (Polyvinyl Chloride) covers over the conductor is called insulation and is provided by extrusion process only. The insulated conductor is called core. The insulation is suitable for 70oC continuous operation.

Twinning (Twisting) :
Two insulated conductors which are called pair are uniformly twisted together with a right hand lay. The twisted pair laid up to form a symmetrical and compact cable, now the pairs stranded and twisted in left hand lay for making a Multipair.

Common Covering :
The cable (laid up pair) is tightly lapped with a PVC tape applied with an overlap of 30%. This facility is not available in single pair.

Identification Thread :
A rip cord is laid through out the length of the cable either below the sheath or below the tape.

Armouring :
In case of Armoured cables, generally Galvanised steel wire/strip Armouring is provided over the laid up pairs (Over the common covering of tape) in the Multipair cables.

Sheath or Outer Covering :
The PVC coating on core in case of single pair cable and on laid up cores in case of multi pair cables is called SHEATH. It is PVC compound suitable for 70o C continuous operation. In case of single pair, The two insulating conductors of the pair are laid side by side and sheathed. In case of multi pair (either Armoured or Unarmoured) is sheathed by Extruded process.

Colour of Sheath :
The colour of the sheath in single pair and in case of Unarmoured Multipaired is grey, but in case of Armoured cables it is available in black colour.

Delivery Length :
The cables are generally delivered in 100 Mtrs. Coils wrapped with Polyethylene / Hessian . The bigger size cables or cables in bigger length are supplied in wooden drums.
