Gas insulated power transformers: A growing technology ... 2: Gas insulated transformer (Toshiba). Construction. Insulation material. GITs are operated at higher temperatures (Class E) than OITs (Class A), and a different class of insulation is therefore used. Oil resistance is not required as the insulation is surrounded by gas, and plastic materials may be used.

GIS | High-Voltage Gas Insulated Switchgear Substations Insulated Substations . A gas insulated substation (GIS) is a high voltage substation in which the major structures are contained in a sealed environment with sulfur hexafluoride gas as the insulating medium. GIS technology originated in Japan, where there was a substantial need to develop technology to make substations as compact as possible.
