the dbk series three-phase transformer has been our company for many years with the high material and vanguard technology specialized production from 100va to 300kva . the sbk series three-phase transformer is our companyin accordance withthe overseas similar product to develop the big electric current energy conservation transformer most newly. their external dimensions and installed the size already standardized, wassubstitute forsimens 4ap. the product conforms to vde0550, iec204-1, iec439, jb5555, gb5226 internationally and so on, the national standards.

is suitable in 50-60hz input, the output voltage 500v , three-phase power supply place.either value of input voltage, the output voltage may be selected, or the joint group and positions.is the air self-cooling type, has the volume slightly, the weight light, the insulation heat-resisting, the rank high characteristic, adds the protection shell or outside the box body may protect the personal safety and guard against pounds and so on the characteristics. this series product uses the import high cold rolling silicon steel plate, the structure is reasonable, the performance is good, the efficiency is high, the noise is low, widely applied to conserving energy e and the power source.
