Audited Supplier The circuit breaker is of outdoor small porcelain column structure, equipped with a CT14 spring operating mechanism. The mechanism is installed in conjunction with the body, which is simple to install, convenient to debug, reliable in action, and suitable for frequent operation. The mechanical life reaches more than 3000 times.
Adopting a compressed air arc extinguishing structure, it has a strong breaking ability, with a cumulative breaking time of up to 12 times at 40kA, setting a record in China. In order to realize good reliable sealing performance, imported sealant pads are used, and the dynamic seal adopts a "V" type sealing ring with spring pressure compensation structure.
The secondary wiring board of the transformer is equipped by a cooperative enterprise, ensuring an annual air leakage rate of less than 1%. The internal current transformer is made of microcrystalline alloy materials with high magnetic conductivity, and the accuracy can reach level 0.2 or 0.2. According to user's needs, 12 transformers can be included, meeting the no-load long line for 50 kilometers without reignition.
