News Room : GE Grid Solutions

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

How Changes in Gas Temperature Affect Gas Density - WIKA blog

Dec 15, 2016 · How Changes in Gas Temperature Affect Gas Density Measurements. Circuit breakers, disconnectors, and switchgear in power transmission and distribution (TD) operations have been using sulfur hexafluoride (SF 6) as insulation for decades. To maintain the excellent thermal conductivity and dielectric strength of SF 6, however, you must keep proper amounts of SF 6, gas purity and minimize the amounts of humidity and byproducts inside the gas chamber.
