BS 5308 Cables

      BS5308 Cable Part 1 Type 2 XLPE-IS-OS-SWA-LSOH

Application

BS5308 Cable Part 1 Type 2 XLPE-IS-OS-SWA-LSOH are generally used when the risk of mechanical damage is increased. The galvanised steel wire armour provides excellent protection. Generally used within industrial process manufacturing plants for communication, data and voice transmission signals and services, Also used for the interconnection of electrical equipment and instruments, the LSOH sheath can reduce toxic smoke and fume emission.
