BS 5308 Cables

PAS 5308 Cables

PAS 5308 Part 1 / Type 3 (Lead Sheath Cables)

PAS 5308 Cable Part 1 Type 3 PE-OS-Lead-SWA-PVC

Applications

PAS 5308 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.They are well adapted to underground use in industrial

applications, in moist areas, where chemical and mechanical protections are needed. The lead sheath brings an

enhanced resistance to aromatic hydrocarbons.

Construction

PAS 5308 Cable Part 1 Type 3 PE-OS-Lead-SWA-PVC

Conductor
