SF6-alternatives Solutions cost

May 30, 2019New load break switch for climate-friendly SF6-alternatives. When designing gas-insulated switchgear (GIS) with SF 6 alternatives, one important task is to compensate the lower insulation performance – to ensure no flashovers occur during operation and dielectric tests.

  • 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.
