Series of Indoor High Voltage Vacuum Circuit Breaker With Embedded Poles   General Description 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,50Hz indoor power distribution equipment with the voltage of 12kV.It can be used for protecting and controling Equipments in the fileds 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 interruters.It can be used for fixed installation unit and also can be used for independent track by equipped with Chassis.
  Product Standard
VIB type vacuum circuit breaker conforms to national standard GB1984-2003HV Vacuum circuit Breaker,DL/T403-2000 Order technical condition of 12kV~40.5kV Vacuum Circuit Breaker and some stipulation of IEC62271-100:2001HV AC Vacuum Circuit Breaker.
  Technical characteristics The vacuum interrupters of VIB type vacuum circuit breaker are used embedded poles by advance APG technology;the primary conducting part is capsulated into an integrated unit by using epoxy resin which makes the insulation condition of primary conducting parts against from impact by exterior enviroment,it can effectively prevent moisture,filths and the damage to the insulation property due to condensed water.
The vacuum interrupter is vertically installed in an insulation house which is made up og epoxy resin cast by advanced APG technology;this kind of structure can maximally reduce the dust accumulation on the surface of vacuum interrupters which ensure the high resitance state even if under the damp,hot and serious filthy enviroment.
The VIB type vacuum circuit breaker uses specialized vacuum interrupter with advanced material and design for their contact, it is with strong breaking capability and high reliability and performed the type test for its electrical life under the condition of autore-close at class E2 level(the breaking operations reaches 274 times for different shor-circuit currents)as per national standard,it is more accordance with the actural usage requirement and realized free of maintenance for its primary part.
