Alternatives for sf 6 | 2020 | Siemens Energy Global

But more and more often, SF 6 is no longer the gas of choice. For a simple reason: if the gas escapes, it contributes to climate change. It is around 23,500 times more warming than the greenhouse gas CO 2 and has a life span of 3,200 years in the earthatmosphere.

Siemens develops gaz sf6-free gas-insulated medium-voltage

Switches and switchgear that use gaz sf6 as the insulating, switching, and extinguishing gas remain an important part of the Siemens portfolio. At this yearHannover Messe, Siemens will present another medium-voltage switchgear that doesn't require sulfur hexafluoride (sf6 gas) as the insulating gas: the 8DAB 12. The system uses clean air consisting only of the natural constituents of ambient air as the insulating gas.

First gaz sf6-free voltage transformers - Siemens Energy Global

Worldwide, many TSOs intend to eliminate greenhouse gases for new installations of gas-insulated equipment and therefore continue to contribute to their voluntary self-commitment in SF 6 reduction. Until now, SF 6 -free voltage transformers were available for voltages up to 245 kV. Recently, Siemens Energy has succeeded to expand the Blue portfolio, which exists of a broad spectrum of CO 2 equivalent-free equipment for air-insulated and gas-insulated switchgear, with a 420 kV voltage

Gas-insulated electrical gear is also more resistant to the effects of pollution and climate, as well as being more reliable in long-term operation because of its controlled operating environment. Exposure to an arc chemically breaks down SF 6 though most of the decomposition products tend to quickly re-form SF 6, a process termed "self-healing".
