Assembly /Inner Sheath:

Two, Three or Four insulated conductors are laid-up together with non-hygroscopic fillers and the assembly is bedded with an extruded layer of PVC. In case of non-armoured cables, this layer may be omitted

Armour:

Aluminum/Galvanized Steel Wires, single core cables shall be Aluminium wire armour, Aluminum/Steel Tapes applied helically over the bedding of multi-core cables as per IEC 60502.

Outer Sheath:

Outer sheath shall be of Extruded PVC Type ST2 as per IEC 60502-1 or Type 9 as BS 6346/5467.Special type of PVC sheathing material such as Fire Retardant PVC, Anti-Termite PVC, Anti-Rodent PVC, Sunlight resistant PVC, Oil Resistant PVC are available on special request. Also, special sheathing materials such as LLDPE, MDPE, HDPE, LSZH, and CPE are available on request.

Fire Performance of Cable Sheaths:

Cables can be supplied with special flame retardant PVC outer sheath to comply With the flame test requirements of IEC 60332-3-22, IEC 60332-3-23 and IEC 60332-3-24, we can also supply cables with Low Smoke Halogen Free (LSHF) material according to IEC 60502-1, BS 7211, BS 6724 or other equivalent standards.
