Zero Halogen Flame Retardant Electrical Cables (ZHFR)

These are eco-friendly wires which are made of multi draw Pure Copper Conductors. Purity of copper offers uniform resistance which makes these wires long lasting. “ZHFR” this value itself suggests that it is flame retardant and Halogen free compound which gives better insulation & Electrical Properties. Application Wiring in all installations where fire safety is more important. Schools, theatres, commercial complexes, air conditioned apartments, high rise buildings, fire alarm and emergency lighting circuits, electronic and computerised installations, modern offices depending heavily on electronic data preservation etc. ZERO HALOGEN FLAME RETARDANT CABLES Single core Unsheathed 1100 V ZHFR Insulated Wired with Copper Conductor FLEXIBLE (Temperature upto 90 C) (Zero Halogen Flame Retardant Thermo Plastic) Nominal crosssectional area of conductor Nos & Diameter of Wires Nominal thickness of insulation Approx.
