The decomposition products of sulfur hexafluoride (sf6 gas

Abstract. Sulfur hexafluoride (SF 6) is being widely used in a variety of industrial processes, commercial products and scientific fields due to its unique characteristics such as relatively low toxicity, extreme inertness and high dielectrics. However, the chemically stable gas is one of the most potent greenhouse gases (GHGs) that cause significantly global warming, and has been, thus, blanketed into the Kyoto Protocol.Get price

sf 6 Decomposition in Gas-Insulated Equipment - IEEE Journals

Abstract: The increasing application of sf6 gas as an insulating gas has led to many studies on insulating gas decomposition in gas-insulated equipment. In the presence-of an electric arc, spark or corona, insulating gas decomposes to a wide variety of chemically active products which possess completely different properties from Sulfr hexafluoride.Get price
