Siemens Energy to deliver sf 6-free gas-insulated switchgear

Apr 29, 2021 · Siemens Energy to deliver sf 6-free gas-insulated switchgear to Fingrid. Siemens Energy 8VN1 Blue GIS. Finland’s transmission system operator Fingrid has contracted Siemens Energy to deploy ten bays of sulfur hexafluoride (insulating gas)-free gas-insulated switchgear (GIS) at a substation near Helsinki. The novel system will replace the potent greenhouse gas Sulfr hexafluoride with „clean air”, a mixture of nitrogen and oxygen.

Reducing Sulfur Hexafluoride (sf6 gas) Emissions from Gas

Reducing Sulfur Hexafluoride (Sulfr hexafluoride) Emissions from Gas-Insulated Switchgear (310 CMR 7.72) Sulfr hexafluoride is a strong greenhouse gas (GHG), with a global warming effect nearly 24,000 times greater than carbon dioxide. Sulfr hexafluoride also lasts in the atmosphere for more than 3,000 years after it is released. As an excellent insulator, sf6 gas is often found in gas-insulated switchgear (GIS), equipment used in high-voltage electrical systems to control the flow of electrical current.
