The wires are insulated with a Flame Retardant (FR) PVC compound, specially formulated and manufactured in house. This FR PVC compound has high Insulation resistance and dielectric strength. This FR PVC has high oxygen andtemperature index. These properties help in retricting the spread of fire, Insulation is applied over the conductor by the process of dual extrusion using state-of-the-art extrusion lines. The outer skin determines the colour identification while the inner layer is pure insulation, which provides extra protection. All wires are subjected to high voltage spark testing to make sure that there are no weak sports in the insulation.
These ISI marked wires meet the requirements of IS 694 : 1990. They additionally offer flame Retardant (FR) properties. This means extra protection against electrical shocks, short circuits and fires.
The company name, size of wire, voltage grade are printedat intervals on the wire to helps in easy indentifications as show below.
