252kV GIS Combined Switchgear

The ZF34-252 GIS produced by the company features a rated current of 5000A and a rated short-circuit breaking current of 63kA. The product is a newly designed integrated, modular, standardized, and compact GIS, occupying less floor space. The circuit breaker employs a self-energy arc-extinguishing principle, offering a simple and reliable structure, strong breaking capacity, and long electrical life. The horizontal circuit breaker is compatible with spring or hydraulic disc spring operating mechanisms, ensuring high reliability and low maintenance requirements. The aluminum alloy enclosure features low temperature rise, corrosion resistance, low eddy current losses, and lighter product weight. The entire bay is transported as a complete unit, significantly reducing on-site construction time. The wiring configurations are flexible, and the product demonstrates strong environmental adaptability, suitable for both indoor and outdoor installation. It is applicable in regions with harsh environmental conditions, high-altitude and earthquake-prone areas, as well as congested urban areas with limited space and mountainous hydropower stations where earthwork excavation is difficult. It is widely applicable to three-phase AC 50Hz power systems with a rated voltage of 252kV, enabling fast, effective, and safe transmission and distribution of electrical energy, including connection, distribution, switching, and dispatching.
