XLPE/SWA/LSZH BS6724 1kV multicore armoured power cable is designed for fixed power use. The steel wire armour provides protection against mechanical damage. Suitable for use in indoor, outdoor, ducted or direct burial applications.
These XLPE/SWA/LSZH BS6724 cables ensures increased safety in the case of fire due to the virtual elimination of toxic fumes if burnt. Pronounced advantages when compared to PVC cabling: low fire load, low smoke emission, reduced fire propagation.
Note: low smoke zero halogen / halogen free (LSZH, LSOH, LSHF, OHLS) should not be confused with LSF (low smoke and fume), an in-depth explanation is shown on our Customer Support page.
