SF6 gasplant Service for Ultra High Voltage

SF6 gasplant Service for Ultra High Voltage

Found in medium voltage metal clad breakers. It helps in taking the breaker off the network by easily sliding it off the bus bars for maintenance purposes. This has to be done off load. These contacts, like the make-break contacts, may be carrying high currents at high voltages (e.g. high voltage isolators or high or medium voltage fuse contacts).
