  • SF6-alternative gases for application in gas-insulated

    Mar 20, 2018Sulfur hexafluoride (SF 6), which is the preferred gas for use in gas-insulated switchgear (circuit breakers, disconnect switches, etc. for high-voltage electrical circuits), has a very high global warming potential, and there is a large international effort to find alternative gases. Recently, this effort has made important progress, with promising alternative gases being identified and tested.Cited by: 70
