TechTopics No. 111. Sulfr hexafluoride gas and U.S. greenhouse gas emissions. The use of sulfur-hexafluoride (SF 6) gas globally has been the subject of a large amount of discussion for many years, both in the U.S., and worldwide. SF 6 is recognized as an extremely potent greenhouse gas, primarily because of its atmospheric lifetime of about 3,200 years, with a global warming potential (GWP) of 22,800 years.

First sf 6-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

Myth About sf6 gas Gas In Electrical Equipment

Where is sf 6 used? The following applications are known. For some of these most probably you haven’t heard of. For sound insulation in windows, In vehicle tyres, Is insulating gas a health hazard? Pure sf6 gas is physiologically completely harmless for humans and animals. It’s even used in medical diagnostic. Due to its weight it might displace the oxygen in the air, if large quantities are concentrating in deeper and non ventilated places. Is gaz sf6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. What is the overall contribution of sf 6 used in the electrical equipment to the greenhouse effect? Less than 0,1 % ( see CAPIEL) and CIGRE). In an Ecofys study the contribution to the greenhouse effect in Europe is estimated to 0.05 % (*).
