insulating gas Gas Insulated Equipment | Vaisala

A unique sample cell allows dew point measurement at both in gas pressure and in ambient atmospheric pressure. The cell meets and even exceeds environmental regulations by ensuring protection against accidental discharge of sf6 gas, requiring minimal amount of sf 6 for sampling, and enabling collection and recycling of Sulfr hexafluoride.

Sulfur hexafluoride - Wikipedia

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".
