  • Sulfur Hexafluoride (SF6) Recovery - Nitrogen Gas Solutions

    Sulfur Hexafluoride (SF. ) Recovery. Sulfur hexafluoride, SF6, is used around the world as a dielectric medium for high-voltage circuit breakers, switchgear, and other electrical equipment. Additionally, it is used for the filling of insulated windows and for the casting of magnesium. SF6 is expensive and is also a powerful green house gas (20,000 times more potent than CO2).

  • Sulfur hexafluoride circuit breaker - Wikipedia

    Sulfur hexafluoride is generally used in present high-voltage circuit breakers at rated voltage higher than 52 kV. Into the 1980s, the pressure necessary to blast the arc was generated mostly by gas heating using arc energy. It is now possible to use low-energy spring-loaded mechanisms to drive high-voltage circuit breakers up to 800 kV.
