ZW30-40.5 series outdoor high voltage vacuum circuit breaker

Series outdoor high-voltage vacuum circuit breaker - product overview
Series outdoor high-voltage vacuum circuit breaker is a three-pole AC outdoor high-voltage electrical equipment. It is suitable for the control and protection of power distribution systems. It can also be used for contact circuit breakers and switching capacitor banks. occasion.
Second product features
It is an outdoor porcelain bottle pillar structure. The mechanism and body have various layout forms such as vertical, handcart, and railway electrification. The whole machine is small in size, light in weight, simple in structure, and easy to install and debug. , without long maintenance cycle.
Excellent breaking performance, short arcing time, and can break the capacitor current in short-circuit circuits.
The anti-fouling level is high and can be used in areas below altitude.
The surface of the product is all treated with Dacromet or hot-dip galvanizing, and the outer casing is made of stainless steel, which has strong anti-corrosion capabilities.
Each phase can be equipped with a built-in current transformer or an external current transformer structure, and the accuracy can be achieved.
Equipped with a transition bracket, it can be used for replacement and modification of oil circuit breakers and other products.
