Toxfree® H05Z-K & H07Z-K: the 90°C halogen-free cable

Thanks to its material design, the Toxfree® H05Z-K & H07Z-K cable is an ultra-flexible and easy-to-handle cable, which guarantees maximum electrical performance and ability in the most demanding switchboards.


Halogen-free rubber insulation allows a maximum conductor temperature of 90°C (compared to 70°C for PVC insulated cables).
