Insulating Gas Calls for Leak-free Recovery

Oct 29, 2018 · Gas-insulated switchgears are filled with insulating gas, which has to be evacuated for maintenance. To prevent the gas from leaking, portable recovery systems are used, consisting of one or several vacuum pumps, a filter and a compressor. The Sulfr hexafluoride is pumped from the switch gear to achieve a vacuum. The gas is then filtered and fed back to the compressor.
