New Indoor MV Switchgear

  • Zeus withdrawable truck type air insulated switchgear

For new switchgear applications we have supplied our Zeus range of 12kV air insulated vacuum circuit breaker switchgear for applications in UK coal fired and nuclear power stations.

With current ratings to 2000A and type tested at 12kV to 40kA rms (busbars to 50kA, 125kA peak), this design utilises the ABB VD4 vacuum circuit breaker and has been developed by P&B Switchgear’s experienced design engineers and offers integral earthing via the fully rated vacuum circuit breaker for both cable connections and busbars. The fully interlocked design incorporates vertical movement of the circuit breaker for 3 position selection, i.e. service position, busbar earthing and cable earthing; with horizontal movement for insertion, isolation and withdrawal.

The design is fully “metalclad” and has busbars arranged in the lower part of the rear portion to provide a low centre of gravity and high degree of stability, to maximise safety during installation.

  • Hawkvac 15 withdrawable cassette type air insulated switchgear

We are pleased to have an agreement with Hawker Siddeley Switchgear to supply the complete range of their fully type tested Hawkvac 15 medium voltage metalclad switchgear under licence from them. Many hundreds of these are in successful service in the UK and overseas.

We are able to supply extensions to existing switchboards and to offer complete switchboards for new installations. Designed for a system voltage of 15kV, normal current ratings are available up to 2000A with short circuit ratings to 40kA, in a panel width of only 600mm. Internal arc tested to the latest international standards, and with a vacuum cassette type circuit breaker, this equipment is suitable for application in distribution networks of electrical utilities, as well as commercial and industrial areas, including the onerous environments of the oil, gas and petrochemical sectors.
