SF6-alternative gases for application in gas-insulated ...· The environmental problems caused by greenhouse gases have received unprecedented attention. Sulfur 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.
