 Three structural features: 

 This series transformer with temperature protection with 65%, 80% two starting voltage tap If you need a smaller starting torque, the choice of 65% tap, if you need to teach a large starting torque can be used 80% tap . The transformer can be assembled in TGX01 series JJ1B word decoupling decompression starter cabinet as the main accessories.
