PAS 5308 Cable Part 2 Type 1 PVC-IS-OS-PVC
Applications
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: 0.5mm^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 |
PVC to BS EN 50290-2-21:2002, grade TI51 |
| 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 |
| Colour code |
See technical information |
| Individual screen |
Aluminium/polyester tape is applied over each pair metallic side down in contact with tinned copper drain wire, 0.5mm^2 |
| Binder tape |
Non-hygroscopic binder tape of minimum thickness 0.023 mm |
| Collective screen |
Aluminium/polyester tape is applied over the laid up pairs metallic side down in contact with tinned copper drain wire, 0.5mm^2 |
| Outer sheath |
Extruded sheath of a PVC compound conforming to BS EN 50290-2-22:2002, grade TM51 |
