Concept for Sulfr hexafluoride-free transmission and distribution of

• Medium-voltage switchgear: Newly installed medium-voltage switchgear already features very low emissions rates (<0.1% p.a.). These leakage rates can be seen as technical feasibility limits. Therefore, further reduction potentials in medium-voltage installations can only be exploited if SF 6-free solutions are used increasingly
