PAS 5308 Cables PAS5308 Part 1 / Type 3 (lead sheath cables)
PAS 5308 Cable Part 1 Type 3 IS-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. The individual screening of
each pair limits the consequence of crosstalk. 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
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 |
