Advantages of SF6-alternatives solution

Alternative gases as sf6-gas substitute Focus on the environment. sf6 gas is an excellent quenching and insulating gas which has been used in the energy sector worldwide for more than 50 years. The energy related development in the high and extra high voltage range would have been impossible without the use of sf6-gas with its excellent dielectric stability and good electric arc quenching properties.

    2020-10-15Current 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
