    Fire Retardant  
FR Building wires are insulated with a Fire Retardant (FR) PVC Compound, specially formulated by one of our Group Companies,to provide added safety.This FRPVC Compound has a high oxygen and temperature index.

These properties help in restricting thespread of fire even at very high temperatures.This special compound also offers high insulation resistance and dielectric strength.

These ISI marked wires meet the requirements of IS 694:1990. In addition, they also offer Fire Retardant properties which meansextra protection against electric shocks, short circuits and fires.
