Why sf6 gas 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 insulating gas 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.
