What is 132kV GIS Switchgear?
A132kV GIS switchgearis a high-voltage electrical device used to isolate, protect, and control power equipment within a substation. Unlike conventional air-insulated switchgear (AIS), GIS usessulfur hexafluoride (SF₆) gasto insulate conductors and components, allowing a morecompact, sealedsystem ideal for urban and space-constrained environments.
GIS is increasingly favored in environments where reliability, minimal maintenance, and resistance to harsh conditions are critical.
Applications of 132kV GIS Switchgear
132kV GIS switchgear is deployed in a wide range of sectors:
- Urban Transmission Substations:Underground or rooftop installations in cities.
- Renewable Energy Plants:Wind farms and solar parks with grid connection nodes.
- Industrial Facilities:Petrochemical complexes, steel plants, and data centers.
- Power Utilities:Transmission hubs, grid substations, and interconnection points.
- Infrastructure Projects:Metro, airports, and smart city grids.
Its sealed and modular design makes it particularly suitable forindoor installationsandharsh environments.
