BS7835 Cable

British Standard BS7835 specifies requirements for single-core and three-core armoured cables with thermosetting insulation - 3.8/6.6kV up to 19/33kV. They are designed to produce low levels of smoke and corrosive gases on exposure to fire compared to the cables specified in British Standard BS6622.

BS7835 Cable selection

We supply a comprehensive range of Medium Voltage (MV) cables, including Low Smoke Zero Halogen (LSZH) thermoplastic oversheathed cables manufactured in accordance with British Standard BS 7835. These cables are designed to have improved fire performance when installed in air. They are also suitable for direct burial installation in free draining soil. It is recommended for the user to seek advice from the supplier for applications requiring installation in any other environment. In particular, these cables are not suitable for use as self-supporting aerial cables, as submarine cable or in water-logged conditions, and in environments where there is a risk of mechanical damage or exposure to excessive heat.
