A review on insulating gas substitute gases and research status of CF3I

Nov 01, 2018 · In 1937, the French first used sulfur hexafluoride (SF 6) as an insulating medium for high-voltage electrical equipment. The high-voltage electrical field has experienced a major revamp and rapid development. In the 1960s, the United States produced the first gas-insulated switchgear (GIS), which used sf6 gas gas as insulating medium.

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.
