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.
