Zw8-12d /630 high voltage vacuum circuit breaker on outdoor column 12KV

It used vacuum interrupter, insulator, electric spring operate structure to improve interrupter, open-close frequency without explode and it was a product of convenience operation with good characteristic and practice. The whole structure of this product was made up of three-phase, pipe in-out line, drier air in box and electric spring operate structure was beside the box which can be used in harsh environment. The vacuum interrupter of this product was made up of ceramic cover, cup magnetic contact terminal, cu-cr material which has good cut-off, link short current capability. This product has small size, light weight, beautiful appearance. The vacuum interrupter and insulator pipe was designed compact and output pole was filled with silicon rubber which can be applied for harsh climate and dirty conditions.

Product Details

Vacuum circuit breaker, airinsulated, electric spring operating mecha nism, high-frequency short-cir

cuit breaking, no fire and explosion danger, easy to operate, is a good, practical, strong performance

products. This product is a vacuum circuit breaker ceramic Shell, cup-shaped Longitudinal magnetic

field electrode structure, copper and chromium contact materials, with excellent short-circuit

current breaking and closing ability. The Product is small in volume, light in weight and beautiful in

appearance. The vacuum interrupter insulation support sleeve is compact in design, and the limit

conductive silicone rubber is injected outside, which can adapt to the severe weather.
