12kV Outdoor High Voltage Vacuum Circuit Breaker

The rated voltage of 12kV outdoor high voltage vacuum circuit breaker include two classes of 12kV & 24kV. Both of them belong to 50Hz three-phase distribution equipment. It adopts vacuum arc extinction and SF6 gas as insulator medium with excellent performance of tightness and electrical insulation. It is full of SF6 gas without leakage easily and not affected by external environment. The spring operation is with miniaturization design and optimization of reliability and stability, adopting main drive of straight moving chain and multistage release system. The action reliability and stability enhance several times than domestic traditional spring operating mechanism. Between axis and cover, the contacts of major loop use adduction and extension type chain structure, with small contact resistance and low temperature-rise. Therefore, outdoor high voltage vacuum circuit breaker is a no-maintenance and the best product in pole-mounted circuit breaker market.
