sf 6 HV Switchgear for mining

Nov 19, 2020Many electricity Transmission and Distribution utilities use high-voltage electro-mechanical plant and switchgear containing Sulfur Hexafluoride (sf6-gas) synthetic gas.. sf 6 is used inside circuit breakers, reclosers, switchgear and wind turbines to extinguish the electrical arc when the contacts inside are separated; enabling the electrical circuit to be broken.

  • Is the end coming for sulfur hexafluoride, the most

    Oct 15, 2020Current EU F-gas regulation prohibits the use of SF 6 in many non-electric applications, but not in MV switchgear. Today, about two thirds of the 15 million MV switchgear units installed in Europe (EU28) use SF 6.When the EU F-gas regulation was last revised in 2014, it was considered that no cost-effective and reliable alternatives to SF 6 were available.
