BS 5308 Cables

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

Application

BS5308 Cable Part 1 Type 2 PE-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 manufacturing plants for communication, data and voice transmission signals and services, Also used for

the interconnection of electrical equipment and instruments, typically in petroleum 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.
