Get PricePurchase SF6 Gas. Sulfur Hexafluoride (SF6) is an excellent gaseous dielectric for high voltage power applications. It has been used extensively in high voltage circuit breakers and other switchgears employed by the power industry. Applications for SF6 include gas insulated transmission lines and gas insulated power distributions.
Get Price6/10/2021But even if 8kTpa of SF6 were released to the atmosphere — e.g., at end-of-life, when switchgear is retired — then this would be equivalent to about 200MTpa of CO2, or around 0.4% of today's global emissions. A study in the 1990s concluded that SF6 emissions had so far contributed <0.1% of all historical manmade warming.
