Sulfur Hexafloride (SF6) Gas Insulated Metal Clad Switchgear gas insulated switchgear (GIS) is designed using three-phase common or single-phase enclosures. This ultimately reduces the space required on-site and associated civil engineering costs. The systems are designed and use the same components for both indoor and outdoor applications.
Gas-Insulated Substations - GIS 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 …

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.
