The CKWZ-12 Intelligent Outdoor Vacuum Circuit Breaker is a next-generation solution engineered for 12kV, 50Hz three-phase AC power distribution systems. Combining a sleek, compact footprint with a maintenance-free architecture, this breaker ensures superior safety and reliability for critical infrastructure.
Rated for 12kV and 50Hz three-phase AC, this unit serves as a critical piece of outdoor power distribution infrastructure. It is primarily designed to break and close load currents, overload currents, and short-circuit currents within the distribution network. Furthermore, it facilitates step-by-step protection for distribution network automation, marking it as a novel and essential asset in modern grid systems.
Ideally suited for protection and control within substation power distribution systems as well as industrial and mining enterprises, the CKWZ-12 is particularly optimized for rural power grids and environments requiring frequent operations. It stands as an excellent solution to meet the evolving demands of urban and rural power grid construction and transformation projects.
Leveraging advanced data processing, the system can rapidly isolate faults on-site while maintaining power supply to non-faulted sections, effectively preventing widespread outages. Furthermore, it establishes robust bidirectional communication with the main station. This allows for the seamless collection, processing, uploading, and execution of both operational data and fault information, ensuring a fully integrated and responsive smart grid solution.
