BS 5308 Part 1 Type 2 PE / CAM / PE / SWA / PVC Instrumentation Cable
Product Overview
The BS 5308 Part 1 Type 2 PE/CAM/PE/SWA/PVC instrumentation cable is designed to carry communication and control signals in a variety of installation types, including those found in the petrochemical industry. The signals can be of analogue, data, or voice type and from a variety of transducers such as pressure, proximity, or microphone.
Part 1 Type 2 cables are designed where a greater degree of mechanical protection is required, namely outdoor/exposed or direct burial at suitable depth. The cable features PE insulation, an Al/PET screen with tinned copper drain wire, PE bedding, galvanised steel wire armour (SWA), and a PVC outer sheath.
