H07Z1-U, H07Z1-R

Non-sheathed single-core installation cables 450/750 V, with LSZH insulation

H07Z1-U, H07Z1-R

APPLICATION

Single core cables, resistant to flame propagation, insulated with halogen−free thermoplastic compound, for fixed wiring. Can be installed in conduits, fixed on surfaces or embedded or in closed analogue systems, particular indicated for situation in which it is necessary to reduce the emission of corrosive smoke and gases, for example in case of fire. In busy oublic places like hospitals, cinemas, schools, etc.
