Industrial Grade Electrical Wires are made using pure bright electrolytic copper & fire retardant PVC compound. These Electrical Wires do not spread fire instead help extinguishing the fire by an endothermic process, which reduces heat in the substrate. These Electrical Wires also give off non-flammable gases and water vapours, which dilutes the oxygen available so as to reduce the burning time. These Industrial Grade Electrical Wires operate occasionally at extremely high temperatures of up to 200 degree C for more than 100 minutes.
