  • Sulfur hexafluoride | F6S - PubChem

    If released into the atmosphere, sulfur hexafluoride will exist in the gas phase in the ambient atmosphere, based on a vapor pressure of 1.78X10+4 mm Hg at 25 °C. Sulfur hexafluoride is one of the heaviest known gases with a vapor density approximately five times greater than air.

  • Sulfur hexafluoride - Wikipedia

    6 gas under pressure is used as an insulator in gas insulated switchgear (GIS) because it has a much higher dielectric strength than air or dry nitrogen. The high dielectric strength is a result of the gashigh electronegativity and density. This property makes it possible to significantly reduce the size of electrical gear.

  • Sulfur hexafluoride circuit breaker - Wikipedia

    The contacts of the breaker are opened in a high-pressure flow of sulfur hexafluoride gas, and an arc is struck between them. The gas captures the conducting free electrons in the arc to form relatively immobile negative ions. This loss of conducting electrons in the arc quickly builds up enough insulation strength to extinguish the arc.
