PAS 5308 Cable Part 2 Type 2 PVC-IS-OS-SWA-PVC
Application
These cables are designed to connect electrical instrumentation and communication systems in and around process plants and similar applications, Generally used to transmit analogue or digital signals in measurement and process control where chemicals may be present. The armoured version are well adapted to underground use in industrial applications where chemical and mechanical protections are needed (refinery areas, chemical plant...).The individual screening of each pair limits the consequence of crosstalk.
