Compact Design: The GIS has a gas insulated construction that allows high voltage components to be installed in a sealed metal container, giving the equipment a compact design. Compared to AIS, GIS is smaller and takes up less space, making it suitable for site limited applications.
High Safety: GIS uses a sealed metal housing to effectively prevent the high voltage components contact with the outside environment, providing a high level of safety. In addition, GIS is designed to provide fire protection and explosion protection, further enhancing the safety of the equipment.
Reliability and Stability: GIS uses special insulating gas (such as SF6 gas) as the insulating medium, which has high electrical insulation properties. The insulating gas is not easy to decompose, making GIS switchgear maintain stability and reliability in long term.
Adapt to Harsh Environment: The sealed design of GIS makes it able to resist harsh environmental conditions, such as high temperature, low temperature, humidity, dusty, etc. Therefore, GIS is preferentially used in coastal areas, high altitude areas, desert areas and other places with harsh environments.
Low Operating Costs: Because of its good insulation performance, GIS can use smaller insulation clearances, which reduces material and installation costs and greatly reduces required installation areas.
Scalability and Flexibility: GIS can be flexibly modularized, and the modules can be added or removed, and the layout can be adjusted as needed. This flexibility makes GIS suitable for power systems of different capacities and configurations, allowing for convenient expansion and upgrades.
