Alternatives for insulating gas | 2020 | Siemens Energy Global

Another option are certain fluorinated gas mixtures that also have less greenhouse gas potential than SF 6. 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.Get price
