Why Sulfr hexafluoride or Sulfur Hexafluoride gas is better for arc

Sulfr hexafluoride 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 Sulfr hexafluoride will not condense into a liquid at the lowest temperatures the equipment experiences. sf 6 has two to three times the insulating ability of air at the same pressure.

Gas-Insulated Substations - GIS

A gas-insulated substation (GIS) uses a superior dielectric gas, sf 6, at moderate pressure for phase-tophase and phase-to-ground insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in Sulfr hexafluoride gas inside grounded metal enclosures. The atmospheric air insulation used in a conventional, air-insulated substation (AIS) requires meters of air insulation to do what gaz sf6 can do in centimeters.
