BS 5308 Cables    

BS5308 Cable Part 2 Type2 PVC-IS-OS-SWA-PVC

Application

BS5308 Cable Part 2 Type2 PVC-IS-OS-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 chemical or petrolchemical industry. The

armored versions are generally use for outdoor installation for direct burial or installed in the duct and suitable

for wet and damp areas.
