vacuum circuit breaker
ZW7-40.5
ZW7-40.5 is a reliable outdoor high voltage vacuum circuit breaker designed for 40.5kV medium and high voltage power systems. Complying with IEC and GB standards, it is widely deployed in outdoor substations, overhead transmission lines and industrial power distribution projects for load switching and system fault protection.
Adopting mature vacuum arc extinction technology, the breaker delivers strong breaking performance and stable insulation. It features arc-free, low-noise and pollution-free operation, supporting frequent switching and long-term full-load stable operation.
Fitted with a high-stability spring operating mechanism, ZW7-40.5 operates smoothly and flexibly with low mechanical wear. It can quickly cut off short-circuit faults and ensure long-term reliable power grid operation.
The integrated fully sealed structure undergoes professional outdoor anti-corrosion treatment, offering excellent waterproof, dustproof and anti-aging performance. It adapts to high-altitude, humid, saline-alkali and heavily polluted harsh outdoor environments.
With a rational overall layout and sturdy structure, the equipment is easy to install and debug on site. It requires minimal daily maintenance and effectively reduces long-term operation costs of power distribution projects.
As essential core protection equipment for 40.5kV outdoor power systems, ZW7-40.5 vacuum circuit breaker features stable performance and high safety. We provide global customers with factory direct supply, complete certifications and professional after-sales service.
