insulating gas gas in medium-voltage switchgear - Siemens USA

In this issue, we discuss the use of sf6 gas (sulfur hexafluoride) gas in medium-voltage switchgear. sf6 gas has been widely used in high-voltage circuit breakers for decades, but its use in medium-voltage is relatively recent. In the medium-voltage arena, SIemens uses insulating gas gas in the load interrupting switch and switch-disconnector in SIMOSEC metal-enclosed load interrupter switchgear rated up to 27.6 kV.

For example, the Zurich-based energy supplier EWZ has been using such a solution since 2015, and in 2019 a 380 kV plant was erected in Bavaria, Germany. However, these gas mixtures lose their effectiveness at very low temperatures. There is also a risk that equipment parts wear out more quickly, which in turn reduces switching capacity.
