Conducting The Energy - Xinfeng Cable

H07Z-U H07Z-R H07Z-K

300/500V Single Core Electrical Cable

Application

Single core, non-sheathed cables are suitable particularly for situations in which low emission of smoke and corrosive gases is required in the case of burning.H07Z-U, H07Z-R, H07Z-K-single core, non-sheathed cables are intended for installation in surface mounted or embedded conduits, or similar closed systems. Suitable for fixed protected installation in, or on, lighting and control gear for voltages up to 1000 V a.c. or, up to 750V d.c. to earth.
