There are many who feel that the circuit breaker function is closed off, in fact, much more than this. Circuit breakers can also be used to distribute power, the implementation of the protection of power lines and motors. Worthy of recognition, the breaker after breaking fault current components generally do not need to change, thanks to its very stable characteristics.

In the field of low-voltage circuit breakers, the results can be said to be very good, but in the high-pressure area to boast. Before that basically rely on the support of foreign high-end technology, Fortunately, this situation has now been improved initially. Power Group has developed the 1100 kilovolt high-voltage circuit breakers, the successful development of the circuit breaker, so this became the country's first independently developed UHV breaker switch companies.

It is reported that the project was developed UHV breaker in 2010 when officially launched, after two years of research and development work, and finally to the performance of new high-voltage circuit breakers stabilized, reached the international advanced level.
