600/1000V XLPE Insulated, LSZH Sheathed Power Cables to BS 8573(Single Core)
FTX300 1RZ1-R (CU/XLPE/LSZH 600/1000V Class 2)
Applications
BS 8573 600/1000V XLPE Insulated, LSZH Sheathed Power 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.
