Gas-Insulated Switchgear(GIS) - Hitachi provides compact, reliable Gas Insulated Switchgear (GIS) with technology that can isolate 550 kV at a single point. The switchgear is composed of isolators that open/close and cut off circuits of current, disconnectors that electrically isolate circuits and open voltage, and other components.
Gas-Insulated Substations - GIS Dielectric Gas. 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.
