FLAMEBLOCKER H07Z1-U, H07Z1-R, H07Z1-K 450/750V

Single-core cables, uncoated, halogen-free, with low smoke and corrosive gases emission.

Application

Single-core, non-corroded cables are suitable in particular in cases where low emissivity of fumes and corrosive gases is required in case of fire. H07Z1-U, R, K cables are designed for embedding in the form of cables mounted on surfaces or similar closed systems. Suitable for permanent or protective installation, or for lighting and electrical equipment for voltages up to 1000V or, up to 750V DC.
