Gas-Insulated Switchgear(GIS) : Transmission and ... 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 Switchgear (GIS) is the name for a unit that houses these components and circuits in a single gas tank with a compact footprint.
Gas-insulated Switchgear Manufacturer in China -KDM main features of a Gas Insulated Switchgear are: GIS System – Photo courtesy: Electrical Engineering Tutorials · Reliability. A gas Insulated Switchgear offers a reliable option against power interruption. This is due to the availability of the SF6 gas that is not prone to faults.
Next level automation and power transmission – from ABB 170 kV GIS systems, ABB has developed a solution which replaces traditional sulfur hexafluoride gas (SF6) with an innovative insulating gas mixture. The insulating properties of the new ABB gas mixture are similar to those of SF6, but much more environmentally sound. Emissions over the service life of the equipment are reduced by 50 percent.
