40.5kV Vacuum Circuit Breaker

XD Baoji Electric Co.,Ltd is one of the leading China 40.5kv vacuum circuit breaker manufacturers and suppliers,Website:http://www.xd-bjelectric.com, as a professional company, our factory is able to produce quality 40.5kV VCB, 40.5kv vacuum circuit breaker products at competitive price.Product Description     VXB-40.5 Series Indoor vacuum circuit breaker is suitable to 40.5kV, three-phase A.C 50Hzpower system. It is used for control and protection switch of power distribution system, such as power plant, substation, industrial and mineral enterprise to receive and distribute power. Especially suitable for the place with frequent operation, it can be used with KYN61 Series switchgear.     The structure of this vacuum circuit breaker is withdrawable truck, the spring mechanism in front of main circuit, the vacuum interrupter was casting in embedded pole. Equipped with isolated contacts and secondary air plug to connect to auxiliary circuit. The driving device was installed at the middle of the frame of VCB, to realize the operation of push in and pull out for VCB in the case of switchgear door closed. It can meet the standard requirments of IEC62271-100、IEC62271-1、GB1984、GB/T11022 etc.     Overall dimension (W×D×H mm)：1192×903×1610.Technical Parameters     Altitude above sea level 1000m and below.     Current rating up to 2500 A/31.5kA.     Module type operating mechanism, simple construction and high reliability.     Floor withdrawable truck, reliable transmission, save effort to push in.        Monolithic casting embedded pole can avoided the vacuum interrupter suffer from mechanical impact, and the influence of  the dust and moisture.     Pass the type test from XIHARI, meet the performance of grade M2-E2-C2.     Mechanical endurance for 10000 times and no maintenance or few maintenance.Technical ParametersItemUnitDataRated voltagekV40.5Rated current A1250、1600、2000、2500Rated frequencyHz50Rated short circuit breaking current kA25、31.5Rated Short-time withstand currentkA/4s25、31.5Rated short circuit making currentkA63、80Rated insulation levelRated power-frequency withstand voltagekV/1min95Rated lightning impulse withstand voltagekV185Breaking number of rated short circuit breaking current Times30Mechanical enduranceTimes10000
