Indoor 12kv Vacuum Circuit Breaker with ISO9001

Exhibition and workshop:VIB1-12Series of Indoor High Voltage Vacuum Circuit Breaker With Embedded PolesGeneral DescriptionIn 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 andmining 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.    It can be used for fixed installation unit and also can be used for independent track by equipped with chassis.Product StandardVIB 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 characteristicsThe 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 of 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 auto re-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.Main Technical SpecificationS.NNameUnitData1Rated voltagekV       122Rated currentA    630        12501600 2000 2500 3150  3Rated short circuit breaking currentkA2025202531.54031.5404Rated peak withstand currentkA5063506380100801005Rated short time withstand currentkA  2025202531.54031.5406Rated short circuit making currentkA5063506380100801007Switching operations of short circuit currentCycle50308Rated operating sequence O-0.3s-CO-180s-CO,O-180s-CO-180s-CO(40kA)9Mechanical enduranceCycle3000010Rated breaking operations of rated currentCycle2000011Rated lighting impulse withstand voltagekV7512Rated power frequency withstand voltagekV4213Contact strokemm9±114Overtravel of contactsmm3.5±0.515Closing speedm/s0.4±0.816Main circuit resistance of each poleμΩ≤40≤45≤40≤3517Opening speedm/s0.9~1.318Contact bouncing duration at closing operationms≤219Simultaneity of three phase closing and openingms≤220Closing timems35~7021Opening timems20~5022Distance between phasesmm150,210,27523DC component 50%   Packaging&Delivery.                                                                              Packaging detailsEach one is wrapped with plastic film in non-solid wooden case.                                                        Delivery detailsWithin 15 days from the date of receiving signed sales confirmation by both parties.                                                                                                                                       Welcome for enquiry and factory visit!/* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
