Highly sensitive sf6 gas fittings

Highly sensitive sf6 gas fittings

SF6 is a highly electronegative gas, an advantage for both dielectric performance and interruption capability. This means that the molecule has a strong electron affinity, so that the gas molecule tends to catch free electrons and build heavily negative ions, which do not move fast.
