  • Sulfur hexafluoride circuit breaker : definition of Sulfur

    Sulphur hexafluoride is generally used in present high-voltage circuit-breakers (of rated voltage higher than 52 kV). In the 1980s and 1990s, 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

  • Hexafluoride - Wikipedia

    2021-3-18A hexafluoride is a chemical compound with the general formula QX n F 6, QX n F 6 m−, or QX n F 6 m+.Many molecules fit this formula. An important hexafluoride is hexafluorosilicic acid (H 2 SiF 6), which is a byproduct of the mining of phosphate rock.In the nuclear industry, uranium hexafluoride (UF 6) is an
