Product Description

12kv vacuum circuit breaker indoor voltage

VSG indoor vacuum circuit breaker is used for indoor 12kv switchgear,it is suitable to control and protect transmission and distribution system such as electric network equipment and industrial&minning industry etc as their protection and control unit.
It can match with KYN28(GBM) type of switchgears.The products meet standards of IEC,this seriesof products include:VCB truck,isolation truck and fuse truck etc.
1.This series of VCB is used integrated design for operating mechanism and VCB body with reasonable and compact arrangement.
2.This series of VCB adopted vertical insulation house against impact due to different weather,it can effectively prevent VIS against damage by exterior factors.
3.With two kinds of installation unit:fixed type and withdrawable type,it can meet different assembling requirements between switchgear and breaker.

Features :

Embedded pole can greatly improve the reliability of insulation, mechanical and breaking performance and really realize the free-maintenance and longer mechanical and electrical life.The embedded poles saves more accessories like fasteners and conduct joints comparing with traditional assembled poles.
2. Mechanism could be manual or motorized.
3.The product is suitable for many kinds of withdrawable metal-clad switchgears  and can be fixed installation.
