House Wire

House wires are mainly used for wiring domestic and commercial structures. They are capable of handling 85°C operating temperature since they are insulated with a flame retardant PVC compound (formulated and manufactured in-house).

Characteristics like these make Wires reliable, energy efficient and highly safe.
