The CMP ZEN range of industrial cable glands is designed and tested to BS6121:2005, and is produced from Brass grade CuZn39Pb3 (CW614N) to EN12168.

The CMP type B323 ZEN cable gland is supplied complete with a unique CMP Cast Integral Earth Lug. This is particularly suitable for use with Medium and High Voltage systems where a high level of protection against short circuit earth fault currents is required. The cable gland concept effectively provides insulation between the cable armour and the equipment and helps to eliminate undesirable circulating currents.

To maximise protection in such circumstances it is normal to connect the armour wires to earth at the supply end of the cable and insulate them from the equipment at the field device end.
