Because there is no air gap in the magnetic circuit,the magnetic direction of the silicon steel strip is  completely consistent with the direction of the  magnetic circuit,the three core columns are arranged  in  an equilateral triangle three-dimensional,the three magnetic circuits are the same length,and are the shortest,and the processing kit is free of waste. Therefore,it  is  an  efficient  and  energy-saving  transformer  that  uses  traditional  materials  but  runs  with  lower  noise  and  more  compact structure.Its excellent performance in reducing loss and saving materials is fully in line with China's energy-saving policy.
