Description

35kv 36kv 40.5kv Outdoor High Voltage Vacuum Circuit Breaker with Permanent Magnet Drive


ZW32-40.5F(M) outdoor high voltage inteligent (permanent magnet)vacuum circuit breaker is mainly composed of integrated solid sealed pole, curent transformer,operating mechanism and box body.Isolation switch can be added.This type of cicuit breaker is of miniaturized design,and the shell is made of high-quality steel box.Current transformers can be selected according to user needs.

The device is mainly used in medium-voltage overhead line power grids as a branching and dosing load curent,overload curent,and short-circuit current.


Environmental conditions

● Ambient temperature:not higher than+40℃,not lower than-15℃;

● Relative humidity of air:daily average value is not greater than 95%,monthly average value is not greater than 90%;

● The altitude does not exceed 1000 meters;

● The seismic intensity does not exceed 8;

● There is no fire,explosion,serious pollution,chemical corrosion and violent vibration.

Note: if the customer has other special requirements,he can put forward at the time of orde,and our company will give the greatest satisfaction.
