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.
