sunel Wholesale - Autotransformer starting transformer, autotransformer .series the sunel production of QZB of type autotransformer suitable for AC 50HZ, rated voltage 380V, rated output capacity of 300KW three phase squirrel cage induction motor, for not frequent the voltage starting under the operating conditions, the use of the characteristics of the step-down transformerbuck low starting current of the motor, in order to improve the transmission network of the motor starter.The transformers conform GB14048.4 and related standard. Autotransformer starter transformer has a 65% to 80% of the groups starting voltage taps, if necessary with a smaller starting torque can be used 65% tap, the starting current, little impact on the grid; larger moment when the choice 80% of the tap; the transformer can be assembled for the main parts in the XJ01, XJ03, JJ1 series autotransformer starter box.
