In the field of medium voltage, especially for 12kv,vacuum circuit breaker has become the main product. This has inseparable relationship with development of embedded technique. The pole isolator has experienced three stage--air isolation, compound isolation, and embedded isolation, which is the third generation of VCB. In first generation, electric part is totally exposed to the air, it's isolation level will be changed with different air humidity, dust and bump during the transportation. In the second stage, vacuum interrupter was protected by epoxy resin. But this kind of cylinder does not cover all the charged part, they will be still affected by external environment. The third stage—embedded poles, fully making use of APG craft, covering all part of vacuum interrupter and two outlet bottoms. Thus not only decreased the size and increased the tolerance of vacuum interrupter, but also making the epoxy resin become the mail isolator and mechanical supporter. The electric-filed distribution and stress distribution is better than all shape of isolation division plate structure. This type of VCB has handcart and fixed structure,, which marches to KYN28A,XGN2,GG-IA or other switchgear, and also can be used for non-oil reform .
