  • A review on SF6 substitute gases and research status of

    Nov 01, 2018In 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 SF 6 gas as insulating
