Gas-insulated electrical gear is also more resistant to the effects of pollution and climate, as well as being more reliable in long-term operation because of its controlled operating environment. Exposure to an arc chemically breaks down SF 6 though most of the decomposition products tend to quickly re-form SF 6, a process termed "self-healing".

gaz sf6: Does its Impact Outweigh its Benefits? | TD World

insulating gas is a member of the GHG group of compounds known as fluorinated gases. While fluorinated gases made up only 3% of the GHG emissions in 2017, they are a concern because of their high GWP. GWP is a calculation of how long the GHG remains in the atmosphere relative to carbon dioxide (CO 2) and how strongly it absorbs infrared radiation (energy). Gases with a higher GWP absorb more radiation than those with a lower GWP and thereby are believed to cause more warming of the earth.
