    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.
