with its own research and development of permanent magnetic actuator for
industrial and mining enterprises, power generation and substation facilities as
electrical control and protection purposes. The product has high reliability and
long life characteristics, especially suitable for frequent operation, repeatedly
breaking conditions, such as short-circuit current of the place.
