Product Name: ZW20-12F Primary and Secondary Fusion Outdoor High Voltage Vacuum Circuit Breaker

Overview:

The ZW20-12F Primary and Secondary Fusion Outdoor High Voltage Vacuum Circuit Breaker is an outdoor power distribution device with a rated voltage of 12kV and a frequency of 50Hz for three-phase AC systems. This circuit breaker employs vacuum arc extinguishing technology and SF6 gas as the insulating medium, making it an improved version of the ZW20-12F pole-mounted vacuum circuit breaker. The casing adopts gas sealing, explosion-proof, and insulation structure technology introduced from Toshiba’s VSP5. The sealing performance of the inlet and outlet conduits has been enhanced, ensuring excellent overall sealing and preventing SF6 gas leakage, making it unaffected by external environmental factors.

The spring operating mechanism of the ZW20-12F has been miniaturized and optimized for reliability and stability. It features a direct-acting chain main transmission and a multi-level trip system, significantly improving the operational reliability and stability compared to traditional spring mechanisms. The main circuit’s contact structure ensures low contact resistance and minimal temperature rise, making the ZW20-12F a maintenance-free product and an excellent choice among pole-mounted circuit breakers.

Moreover, the ZW20-12F includes overcurrent protection, spring energy storage indication, and is equipped with an aviation connector for secondary electrical connections, making it easy to integrate with intelligent controllers. Its superior electrical and mechanical performance allows it to be widely used for breaking and making load currents and short-circuit currents in 10kV power systems, especially suitable for substations and industrial power distribution systems, as well as frequently operated power grids.
