PAS 5308 Cable Part 1 Type 1 PE-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: 0.5mm^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
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 ontact 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
Sheath colour	Generally black
