  • Eco-efficient alternatives to SF6: Continuing the AirPlus

    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. But SF 6 can also serve as switching medium, today frequently applied in ring main units (RMUs).

  • Is the end coming for sulfur hexafluoride, the most powerful

    Oct 15, 2020 · 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. In the MV sector, however, this picture is slowly changing thanks to technological progress.
