dilo Transformers SF6-alternative gases technical

Gas 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 ...
