The company now covers an area of 77,601 square meters (116 acres), and has a plant area of 20,000 square meters. It is a national high-tech enterprise that specializes in the research and development, manufacturing, sales and service of intelligent medium & high voltage switchgear. Also the company is a leading manufacturer for solid insulated switchgear in China. The AB-3S-24 Series breakers are recently-developed pole-mounted intelligent vacuum circuit breakers of a new generation, which absorb the advanced domestic and foreign technologies adopted by our company, embody the design concept of being "intelligent, energy-saving, environmentally-friendly and maintenance-free" and comply with the actual conditions of China's power distribution network and the construction requirements of smart grid. These products can be used as switches at the 10kV side of substation and 10kV outgoing line of main transformer as well as pole-mounted switches for power distribution networks. They integrate such functions as measurement, control, protection, communication, fault isolation and network reconfiguration, with high automatic and intelligent degree; they are top choices for equipment of power distribution network automation and miniaturized substations.This product conforms to IEC60044-1, IEC60060, IEC60068-2, IEC60099-4, IEC60255-27, IEC60270, IEC60280.1, IEC60529, IEC60694, IEC60815-1, IEC60870-5-101, IEC61000-4, IEC61243-5, IEC62271,standards, etc.Major Technical Parameters are Shown Below:Rated voltage24 kVRated current1,250/1,600 ARated frequency50 HzRated short-duration (1 min) power frequency withstand voltage65/79 kVRated short-circuit breaking current25/31.5 kARated short-duration withstand current (4s)25/31.5 kARated lightning impluse withstand voltage(to earth/break)125/145 kVRated short-circuit making current (peak value)63/80 kARated peak withstand current63/80 kARated short-circuit currentbreaking times30 timesMechanical service life of vacuum circuit breaker20,000 timesCT transformation ratio600/1 or 1,250/1Rated operating sequence of circuit breakerO-0.3s-CO-180s-COTotal weight200+25 kgShould you have any question about this product, please feel free to contact us.We are looking forward to co-operations with customers from all over the world!
