1100 Volt. Grade Aluminium/Copper conductor XLPE/PVC insulated, cores laid up together, PVC inner sheathed type ST-1, G.I. wire/strip armoured outer PVC sheathed 600/1100 volts grade cable generally conforming to IS:7098/Part- 1/1988&1554/pt-1/1988.
Armoured cable is the name given to any electrical cable constructed with a layer of aluminium wire armour or steel wire/strip armour. The armour sits below the sheath of the cable to provide protection for the conductor and insulating layers.When electrical cable is required for use outside or in direct burial projects, it must have mechanical protection. Armour provide such protection-as well as enabling the cable to withstand higher pulling loads.
