  • A Literature Review on SF6 Gas Alternatives for use on the

    2019-9-15From literature, there are a number of attractive alternatives to SF 6 including AirPlus (developed by 3M and ABB), g3 (developed by 3M and GE), HFO1234zee and solid epoxy. The identified possible interrupting alternatives to SF 6 are g3 and vacuum interruption. Pending engagement with manufacturers, it is anticipated that these mediums will be retro-
