 PAS 5308 Part 2 / Type 1 (unarmoured cables)

       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

PAS 5308 Cable Part 2 Type 1 PVC-IS-OS-PVC

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
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, 0.5mm²

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, 0.5mm²

Outer sheath

Extruded sheath of a PVC compound conforming to BS EN 50290-2-22:2002, grade TM51

Sheath colour

Generally black
