High Voltage Switchgear - above 36kV

Mitsubishi Electric has been supplying gas insulated switchgear (GIS) and gas circuit breakers (GCB) since the early 1970s. We currently have some 20,000 GCBs and 5,000 bays of GIS in service around the world.

Our equipment includes dead tank and live tank GCBs and covers the voltage range from 36kV to 1000kV. In Australia we have supplied many of the major utilities and have proven our ability to meet Australian Standards and requirements of the local operating environment.
