  • Why SF6 or Sulfur Hexafluoride gas is better for arc

    SF6 is hazard free Sulfur hexa fluoride is an inert, nontoxic, colorless, odorless, tasteless, and nonflammable gas consisting of a sulfur atom surrounded by and tightly bonded to six fluorine atoms. It is about five times as dense as air. SF6 is used in GIS – gas insulated system at pressures from 400 to 600 kPa absolute.
