Yikes, I hope you realise that gas insulated switchgear is sealed, maintenance free and not piped to a central gas storage vessel or gas generator.

Start with Wikipedia, Google SF6 switchgear, look on company sites such as Siemens and ABB for extensive SF6 and substation documentation and theory (all free).

Start with the basics and everything will become clear.
