XLPE insulated SWA cable, British Standard BS5467 cable specification covers the requirements for low voltage armored cables - both galvanized steel wire armored (multi-core) and non-magnetic aluminum wire armored (single core) - with thermosetting insulation of rated voltages 600/1000V for use in fixed installation in industrial wiring, mains distribution, auxiliary control and similar applications, where there is risk of mechanical damage and some form of protection is required.
BS5467 specifies the number of cores (single-core / two-core / three-core / four-core / five-core and up to 48 cores for auxiliary cables) and the type of conductor, which can be plain annealed stranded copper (Cu) or solid aluminum (Al). The Standard allows color-coded or number-coded core identification. These low voltage cross-linked polyethylene (XLPE) insulated and polyvinyl chloride (PVC) sheathed armored cables are designed to specifications that ensure the insulation and other components are suitable for sustained operations at a maximum conductor temperature of 90℃, and at a maximum short-circuit conductor temperature of 250℃.
XLPE insulated SWA cable BS5467 is widely used power cables both in the UK and prevalent in international projects specified to British standards. They are hard-wearing and suitable for indoor, underground (direct burial in free draining soil or embedded in concrete) and outdoors without additional protection due to the mechanical protection afforded by their armour and the UV stable and water resistant nature of their sheathing. For applications requiring Low Smoke Zero Halogen (LSZH) sheathing, please refer to our British Standard BS6724 for an LSZH equivalent to BS5467.
