gaz sf6 Decomposition in Gas-Insulated Equipment - IEEE Journals

Abstract: The increasing application of Sulfr hexafluoride as an insulating gas has led to many studies on sf 6 decomposition in gas-insulated equipment. In the presence-of an electric arc, spark or corona, Sulfr hexafluoride decomposes to a wide variety of chemically active products which possess completely different properties from sf 6.Get price

The decomposition products of sulfur hexafluoride (gaz sf6

From the environmental and health points of view, it is necessary to mitigate and control the emissions of the decomposition products from SF 6 destruction processes because most of them (e.g. S 2 F 10, SF 4 and HF) are highly reactive, corrosive and toxic, and few of them are also potent GHGs. This article aimed to introduce the fullyGet price
