    Abstract - (Show below) - (Hide below)

    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.

    Scope - (Show below) - (Hide below)

    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.
