PAS 5308 Part 1

 PAS 5308 Part 1 / Type 2 (armoured cables)

       PAS 5308 Cable Part 1 Type 2 PE-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.

Construction

PAS 5308 Cable Part 1 Type 2 PE-IS-OS-SWA-PVC

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

Insulation

thermoplastic PE to BS EN 50290-2-23:2002, grade L/MD or a cross-linked PE to BS EN 50290-2-29

Pairing

Two insulated conductors uniformly twisted together with a lay not exceeding
100mm, Two-pair cables without individual pair screens (quads) shall have four cores laid in quad formation round a central dummy
