Telephone Cables


Solid annealed bare copper 0.5/0.8mm as per ASTM B-3/IEC 60228 Class 1


Solid polyethylene as per ASTM D 1248/IEC 60708

Cable Core Assembly & Core Wrapping

Individual conductors are twisted into pairs and wrapped with PETP tape

Strength Member:

Aramid yarn as non-metallic strength member is placed inside the sheath to provide longitudinal strength


PE is extruded over the core to provide protection against mechanical damage, degradation by sunlight and

water ingress


A ripcord made of polyamide is placed parallel to the core to facilitate sheath removal
