Sulfr hexafluoride gas in medium-voltage switchgear - Siemens USA

Siemens estimated that the annual leakage rate is below 0.1% per year, so no replenishment of the gas is needed over the life of the switchgear. Since the switch enclosure is sealed-for-life, there is no need to provide for periodic maintenance of the gas.Get price

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
