The FZW32-/630-20 outdoor high voltage vacuum load break switch is a new type of load switch designed and manufactured by integrating mature experiences from domestic switch production and advanced international technology. This load break switch is composed of disconnect blade, vacuum interrupter and operation mechanism. It adopts the principle of vacuum arc-extinguishing chamber, featuring strong arc-extinguishing capability, reliable performance, long lifespan, small size, no explosion risk, and no pollution. When paired with corresponding vacuum load switches, it can be used in power, metallurgy, mining, chemical, and other sectors’ power distribution systems as a control device, especially suitable for places that require frequent operations.
