The main characteristic:
1. Equipped with excellent permanent magnet construction. It uses (single) double steady magnetic circuit, which leave out the complex store energy, lock catch and so on mechanical device. The amount of parts reduces above 70% that increases the reliability and life of machine.
2. Primary galvanic circle is installed in epoxy resin insulating cylinder made by APG craft. It can prevent impact of external forces, dirty environment to arc extinguish chamber.
3. Use electronization intelligent control unit, with high reliability.
4. 50 thousand times mechanical life realize the free maintenance.
5. Ciruit breaker can be made handcart-type or fix-type, and it can coordinate with switchgear cubicle and be easy oil free transformed
