BS 5308 Cables

      BS5308 Cable Part 1 Type 2 PE-IS-OS-Lead-SWA-PVC

Application

BS5308 Cable Part 1 Type 2 PE-IS-OS-Lead-SWA-PVC are generally used when the risk of mechanical damage is increased. The galvanised steel wire armour provides excellent protection. Generally used within industrial process anufacturing plants for communication, data and voice transmission signals and services, Also used for the interconnection of electrical equipment and instruments, typically in petroleum industry. They are well adapted to underground use in industrial applications, in moist areas, where chemical and mechanical protections are needed. The lead heath brings an enhanced resistance to aromatic hydrocarbons.
