PAS5308 Part 1 / Type 3 (lead sheath cables)
PAS 5308 Cable Part 1 Type 3 OS-Lead SWA

 

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.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 OS-Lead SWA

Conductor Annealed copper, sizes: 0.5mm² mulitistranded(Class 5), 0.5 mm² and 1.0 mm² solid(Class 1), 1.5mm² or 2.5 multistranded(Class 2) to BS EN 60228
