Product Overview
The H07Z1-K 35 mm² 450/750V single core cable is a specialized low smoke zero halogen (LSZH) wire designed for internal wiring in conduit, trunking, and fixed protected installations. Manufactured to meet rigorous international requirements, this cable utilizes fine-stranded annealed copper conductors enclosed in a high-grade halogen-free flame retardant (HFFR) compound. In the event of a fire, it ensures minimal smoke emission and no toxic corrosive gases, protecting human life and sensitive electronic equipment in high-occupancy commercial and industrial complexes.
