Main Electrical Substation Upgrades - MRO MagazineMRO …· Consequently, the use of sulphur hexafluoride (SF6) insulated switchgear, also known as gas-insulated switchgear (or GIS), was considered. Given the high dielectric strength of SF6, GIS provides a more compact installation, with a footprint that is approximately 50 per cent of the size of equivalent air-insulated switchgear.
