Gis switch energy storage

Where is Gas-insulated switchgear (GIS) used?

Gas-insulated switchgear (GIS) is used where space is limited, such as in extensions, city buildings, on roofs, offshore platforms, industrial plants, and hydropower plants. Hitachi Energy has always been and continues to drive innovation in GIS technology in ratings, operations, switching technology, smart control and supervision, and compactness.

What is a GIS switchgear?

The structure will stand next to the thermal power plant in a designated switchyard area. The design of the GIS switchgear will include a double busbar with eight feeder bays, two bus sections, two bus couplers, and four transformer bays (the thermal generator transformers will be located within the thermal power plant).

What is the difference between a GIS Unit and a switchgear unit?

The main feature of a GIS device is the use of SF6, an inert gas with exceptional insulation properties, and chemical and thermal stability. By comparison, a GIS unit only requires centimeters for effective insulation, while an air-insulated switchgear unit would need meters to perform the same function.

Does Hitachi energy offer gas insulated switchgear?

Hitachi Energy's gas-insulated switchgear (GIS) portfolio offers a complete range of products for all ratings and applications from 72.5 kV to 1200 kV.

Why is GIS important for coal-fired power plants?

So, the adoption of GIS is recommended to provide a high reliability and efficient switching and protection way in connection with the new coal-fired combined heat and power plant and the new/existing power lines after taking into account the safety, technical, environmental, financial, and economical factors between the GIS and AIS.

Why should you choose Hitachi energy GIS?

Hitachi Energy's GIS offers outstanding reliability, operational safety and environmental compatibility. It provides a complete range of products for all ratings and applications from 72.5 kV to 1200 kV, matching current and future requirements for modern switchgear. Why Hitachi Energy?
