Features:
1. Newly designed integrated, modular, standardized, miniaturized GIS, with less floor space;
2. The circuit breaker equipped with GIS adopts the self-energized arc extinguishing principle of "thermal expansion + blowing assistance", with simple and reliable structure, strong breaking capacity, three-cycle full breaking time, and long electrical life;
3. The circuit breaker is equipped with CTB-Ⅰ spring operating mechanism, which has simple and compact structure, high reliability, less maintenance workload, and mechanical life of up to 10,000 times, meeting the requirements of "oil-free";
4. The metal aluminum alloy shell has low temperature rise, corrosion resistance, small eddy current, lighter product quality, and can be transported in whole compartments, greatly shortening the on-site construction period;
5. The wiring form is flexible and has strong environmental adaptability. It can be arranged indoors or outdoors. It is suitable for areas with harsh environmental conditions, high altitude and earthquake-prone areas, as well as downtown areas with tight land use and mountain hydropower stations with difficult earthwork excavation.
Application:
Applicable to three-phase AC 50Hz, rated voltage 72.5~126kV power system. Quickly, effectively and safely realize the connection, distribution, switching and dispatching of power transmission and distribution network.
Scope:
Provide safe and reliable electrical transmission and distribution equipment for different users. The products not only cover the various units of the State Grid, photovoltaic, wind, water conservancy, waste incineration and other power generation enterprises, coal, chemical, metallurgy and other industrial and mining enterprises, but also railway, offshore, government supervision and other key projects. The products are exported to overseas countries such as Russia, Laos, Indonesia and so on.
