Why sf6 gas or Sulfur Hexafluoride gas is better for arc

insulating gas 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 insulating 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.
