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: 0.5mm^2 mulitistranded(Class 5), 0.5 mm^2 and 1.0 mm^2 solid(Class 1), 1.5mm^2 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 |
