sulfur hexafluoride REFILLING leak guide

In High Voltage Relays a mixture of sulfur hexafluoride, SF6, and nitrogen is used primarily because of the way the gas performs during switching. SF6 is an excellent insulator but once the switch is closed if the relay bounces the SF6 becomes easily ionized and carries the arc current.

2018/3/12Gas insulated transformers (GITs) have been in use since the 1960s, but use has been restricted due to higher costs and other reasons. Gas is used as an insulating and cooling agent in gas insulated transformers. Sulphur hexafluoride (SF 6 ) is the main gas used in these types of transformer at present although other gases are under development.
