Sulfur Hexafloride (SF6) Gas Insulated Metal Clad Switchgear

The 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.
