News Room : GE Grid Solutions

It was just two years ago that GE announced a breakthrough in developing a substitute for sf 6 in gas-insulated equipment. Such a substitute had become necessary because gaz 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.
