PAS 5308 Cable Part 2 Type 1 PVC-IS-OS-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 individual screening of each pair limits the consequence of crosstalk.
Construction
Conductor |
Annealed copper, sizes: 0.5mm² and 0.75mm² mulitistranded(Class 5), 1.5mm² and 2.5mm² multistranded(Class 2) to BS EN 60228 |
Insulation |
PVC to BS EN 50290-2-21:2002, grade TI51 |
Pairing |
Two insulated conductors uniformly twisted together with a lay not exceeding |
Colour code |
