Why sf 6 or Sulfur Hexafluoride gas is better for arc

gaz sf6 is used in GIS – gas insulated system at pressures from 400 to 600 kPa absolute. Wide range of pressure The pressure is chosen so that the sf6 gas will not condense into a liquid at the lowest temperatures the equipment experiences. insulating gas has two to three times the insulating ability of air at the same pressure.
