BS5308 Cable Part 2 Type2 PVC-OS-SWA-PVC
Application
BS5308 Cable Part 2 Type2 PVC-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 reas.
