HG11-145 Gas-Insulated Metal-Enclosed Switchgear 145kV, 3150A, 40kA
The HG11-145 GIS (Gas-Insulated Switchgear) is composed of several standard functional modules, such as the GCB circuit breaker, TPS isolation-grounding combination switch, PT voltage transformer, CT current transformer, BSG bushings, and BUS busbar. These modules share the same interface forms and dimensions, allowing for various combinations to meet the design and layout requirements of different substations. Each module is combined based on principles that facilitate future expansions and modifications, with gas-insulated isolators minimizing the mutual influence between adjacent modules.
The flexible modular design enables the substation to be easily optimized for design and layout, considering various conditions and factors such as the main circuit arrangement, incoming lines and cable routing, building dimensions, accessibility, reserved expansion space, and rapid fault elimination.
