Defines requirements for the construction, dimensions and mechanical and physical properties of multipair cables with halogen-free insulation and sheaths, having reduced fire propagation performance, and low emission of smoke when affected by fire.

This section of BS 7870 specifies requirements for the construction, dimensions and mechanical and physical properties of multipair cables with halogen-free insulation and sheaths, having reduced fire propagation performance and low emission of smoke when affected by fire.

It specifies requirements for multipair cables (up to 200-pair) with copper conductors, a collective screen and armouring consisting of a single layer of steel wires or a double layer of steel tapes.

It specifies requirements for both Type 1 and Type 2 cables, which are defined as follows:

  • Type 1: cable designed for the installation and operating conditions prevailing in a conventional fossil fuelled power station or equivalent location;
  • Type 2: cable designed for the installation and operating conditions prevailing in a PWR power station, but excluding location in or around the containment area.

The requirements specified in this section of BS 7870 are applicable to both Type 1 and Type 2 cables unless otherwise indicated.

This section of BS 7870 is applicable to cables for use in and around power stations and other installations having similar cable densities.

NOTE A “guide to use?? is given in Annex A.
