odm SF6 insulated leakage

Deployment of the g3 gas mixture as a replacement for SF6 has taken a major step forward: the F35-145 kV gas-insulated substation (GIS) is now SF6-free too. It has the same physical footprint as its SF6-based GIS predecessor and can operate at ambient temperatures as low as -25 &C.

    Jan 01, 2015SF6 also lasts in the atmosphere for more than 3,000 years after it is released. As an excellent insulator, SF6 is often found in gas-insulated switchgear (GIS), equipment used in high-voltage electrical systems to control the flow of electrical current. SF6 routinely leaks into the atmosphere from closures and joints in GIS equipment.
