Product Details

Product Details：
HG11-145 GIS is composed of several standard functional modules, such as circuit breaker GCB, isolation-earthing combination switch (TPS), voltage transformer (VT), current transformer (CT), bushing (BSG) and busbar(BUS). These modules have the same interface form and size, and various modules can be arbitrarily combined to meet the design and layout requirements of various substations. Each module is assembled in a manner that facilitates future reconstruction and expansion, and gas-isolating insulators minimize the interaction between adjacent modules.
The flexible modular design facilitates the optimization of the design and layout of the substation, and various conditions and factors, such as main wiring, incoming line and cable routing, building size, trafficability, reserved extension and fast troubleshooting can be fully and specifically considered.
