Product Overview
The H05Z1-U 2.5 mm² 450/750V cable is a single-core, solid copper conductor installation wire insulated with high-grade Halogen-Free Flame Retardant (HFFR) compound. Specifically manufactured for fixed protected installations, this cable is engineered to meet strict international safety parameters. In the event of a fire, it ensures minimal smoke density, zero halogen emissions, and high flame propagation resistance, protecting both human life and critical electrical infrastructure in complex architectural environments.
