A high-voltage vacuum circuit breaker is a circuit breaker in which the contacts are split and closed in a high-vacuum bubble. "Vacuum circuit breaker" is named because the arc extinguishing medium and the insulating medium of the contact gap behind the arc are both high vacuum; It has the advantages of small size, light weight, suitable for frequent operation, and no need for maintenance for arc extinguishing, and is widely used in the distribution network.
The production of high-voltage vacuum circuit breakers includes: ZN63A-12 (VS1.650, 800, 1000, high prototype, side-mounted VBM7, VD4, VB1, permanent magnet, SVM, 24KV, ZN28, ZN23, ZW6, ZW7, ZW32, ZWB, LWB, ZN85, KYN1, JYN2) and other series of indoor and outdoor high-voltage vacuum circuit breakers.
We produce high-voltage disconnectors, high-voltage vacuum circuit breakers, and column vacuum circuit breaker series products.
