SF6 Equipment Replacement cart system for Substation

Jan 11, 2019 · GIS containing SF6 gases are typically found in most if not all substations and at many power generating facilities, including natural gas plants, wind farms, solar parks, and geothermal plants. Although SF6 is non-toxic, the gas is one of the most potent GHGs with a global warming potential of 23,900 and an atmospheric lifetime of 3,200 years.

    It was just two years ago that GE announced a breakthrough in developing a substitute for SF6 in gas-insulated equipment. Such a substitute had become necessary because SF6, despite its undeniable qualities—its arc-quenching and dielectric capabilities—has a global warming potential (GWP) 23,500 times that of CO2, with a lifetime in the atmosphere of over 3,000 years.
