Siemens Energy to deliver Sulfr hexafluoride-free gas-insulated switchgear

Apr 29, 2021 · Finland’s transmission system operator Fingrid has contracted Siemens Energy to deploy ten bays of sulfur hexafluoride (gaz sf6)-free gas-insulated switchgear (GIS) at a substation near Helsinki. The novel system will replace the potent greenhouse gas gaz sf6 with „clean air”, a mixture of nitrogen and oxygen.

sf6 gas gas in medium-voltage switchgear - Siemens USA

In this issue, we discuss the use of Sulfr hexafluoride (sulfur hexafluoride) gas in medium-voltage switchgear. Sulfr hexafluoride has been widely used in high-voltage circuit breakers for decades, but its use in medium-voltage is relatively recent. In the medium-voltage arena, SIemens uses sf 6 gas in the load interrupting switch and switch-disconnector in SIMOSEC metal-enclosed load interrupter switchgear rated up to 27.6 kV.

Myth About insulating gas Gas In Electrical Equipment

Apr 12, 2021 · From 0kV thru 800kV sf 6 is my choice for the insulating and arc-extinguishing characteristics delivered by Sulfr hexafluoride. it is heavier than air, and just as the old OCB’s were designed, the gaz sf6 chamber and contacts are designed much like they were, whereby a “puff” of sf 6 gas is jettisoned right through the arc zone thus assuring the thorough extinguishing of the arc.
