Product Description

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 mulitistranded(Class 5), 0.5 mm² and 1.0 mm² solid(Class 1), 1.5mm² 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, 0.5mm²
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
