BS5308 / PAS5308 Cables

To many specifiers BS5308 is regarded as “the” standard for instrumentation cables and it’s replacement by BS EN 50288-7 removes
cable designs which are so well established that withdrawal of the standard could cause some difficulties. Cables manufactured exactly
to BS5308 are not covered in the new BS EN 50288-7 standard and so to avoid the complete loss of BS5308, it has been revised and
reissued as PAS5308, a Publically Available Specification (PAS).  This does not carry the same weight as a BS5308 did previously
but it allows for the technical content (with some additions/minor modifications) to be retained in a published document.

The data provided in this section relates primarily to BS5308 as this is still more commonly used than PAS5308
PAS 5308 cables have addition options including XLPE insulation and alternative core colours

These cables are designed to connect electrical instrumentation and communication systems in and around process plants in the oil,
gas, petro-chemical industries, power generators and other process industries. They may also be used on intrinsically safe circuits.
They are not for direct connection to the public mains supply. Armoured cables are suitable for direct burial. They are
also available with mica-taped conductors, in which case they also comply with IEC 60331.

Temperature Rating: 65°C (maximum conductor operating temperature).
