ZN63A (VS1)-12 series of 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 & mining industry etc as their protection and control unit.
It can match with KYN28 (GZS1), XGN and GG1-A series of switchgears. The Products meet standards of GB1984-2003, this series of products include: VCB truck, isolation truck and Fuse truck Etc.

VSM series of indoor high voltage vacuum circuit breaker is adopted front and rare construction for their permanent magnetic and vacuum interrupters. The main conducting circuit is with floor-standing type, the upper and lower outlet terminal and vacuum interrupters are installed in one insulation house. The insulation house is casted with epoxy resin material by APG technology, which can protect the surface of the vacuum interrupters against dust accumulation and impact. It also has good insulation property under humid, hot and pollution ambient condition.
The vacuum circuit breaker with permanent mechanism is air-insulated, used for indoor installation for different kind of power load, it is suitable for electrical net construction and reconstruction project in municipal net, rural net, mineral and railway net system, especially used in that fields which require frequently switching and have some requirement for short circuit operation cycles. This product was introduced by some international advance technique and processing technology with characteristics of intelligence, high reliability, long endurance and free maintenance etc. 

In order to meet the market requirements for high quality VCB as well as their adaptation with its switchgear, our company develops this new generation of VIB type indoor high voltage vacuum circuit breaker. It is three-phase AC, 50 Hz indoor power distribution equipment with the voltage of 12kV. It can be used for protecting and controlling equipments in the fields of power supply and distribution system such as substation and industrial and mining industry etc.
VIB series vacuum circuit breaker has taken into consideration of reliable interlock function which can be frequently operated at the rated current and with the capability of many times operations of breaking short-circuit current and fault current. This series of vacuum circuit breaker is an integrated unit by adopting the front and rear arrangement between operating mechanism and vacuum interrupters. It can be used for fixed installation unit and also can be used for independent track by equipped with Chassis.
 

VIB-24 Indoor High Voltage Vacuum Circuit Breaker is a new generation vacuum circuit breaker for Shaanxi Shaankai-Longxiang Electrical Ltd.
