Fire Resisting Cables
600/1000V Mica+XLPE Insulated, LSZH Sheathed Power Cables to BS 8573 (Single Core)
FFX300 1mRZ1-R (CU/MGT+XLPE/LSZH 600/1000V Class 2)
APPLICATION
These 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.
