Why sf 6 or Sulfur Hexafluoride gas is better for arc

gaz sf6 decomposes in the high temperature of an electric arc or spark, but the decomposed gas recombines back into sf 6 so well that it is not necessary to replenish the sf 6 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.Get price
