Byproducts of Sulfur Hexafluoride (sf6 gas) Use in the Electric

Sulfur hexafluoride (SF 6) is a relatively nontoxic gas used in a number of applications for its inert qualities. The dielectric and other physical and chemical properties related to its lack of reactivity have led to the extensive use of SF 6 as an insulating medium in switching equipment (e.g., circuit breakers) by electric utilities. While SF 6

Why sf 6 or Sulfur Hexafluoride gas is better for arc

sf 6 decomposes in the high temperature of an electric arc or spark, but the decomposed gas recombines back into Sulfr hexafluoride so well that it is not necessary to replenish the sf6 gas in GIS. There are some reactive decomposition byproducts formed because of the interaction of sulfur and fluorine ions with trace amounts of moisture, air, and other contaminants.
