Fire Resisting Cable


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.

STANDARDS

CABLE CONSTRUCTION

Conductor : Annealed copper conductor, stranded according to BS EN 60228 class 2.

Fire Barrier : Mica glass tape.

Insulation : XLPE type GP 8 according to BS 7655-1.3. HEPR type GP 6 according to BS 7655-1.2 or crosslinked

polyolefin material type EI 5 according to BS EN 50363-5 can be offered as option.

Inner Covering Option : The optional inner covering, where used, shall consist of an extruded layer of synthetic

polymeric material. It shall surround the single core and the laid-up two, three, four or five cores, giving the

assembly a practically circular shape.
