BS 8573 Cables

Five-core 600/1000V XLPE Insulation, LSZH Sheath Cables to BS 8573


BS 8573 XLPE insulated and LSZH sheathed cables are generally used for fixed installation. Suitable for building wiring, especially in areas where smoke and fume emissions may cause a potential threat to life but not for burial in the ground, either directly or in ducts.


Basic design to BS 8573:2012
