Gas-insulated Switchgear ELK-3 GIS for maximum performance, 550 kV. 2. Introduction. ABB has been pioneering the development and manufacturing of SF. 6Gas Insulated Switchgear (GIS) since the sixties. The first 170 kV GIS was installed in 1969 at Sempersteig (Zurich/Switzerland). The next important milestone was the delivery of the first 500 kV GIS at Claireville (Ontario/Canada).

A gas-insulated substation (GIS) uses a superior dielectric gas, SF6, at moderate pressure for phase-tophase and phase-to-ground insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in SF6 gas inside grounded metal enclosures. The atmospheric air insulation used in a conventional, air-insulated substation (AIS)
