The three-dimensional iron core oil-immersed transformer is a new type of high-reliability transformer product with a more reasonable structure, superior performance, and lower manufacturing cost. The product breaks through the traditional planar structure by adopting a two-phase symmetric three-dimensional structure. Moreover, since there is no air gap in its magnetic circuit, the magnetic conductivity direction of the silicon steel strip is completely aligned with the direction of the magnetic circuit. The three core columns are arranged in an equilateral triangular three-dimensional layout, the lengths of the three magnetic circuits are equal, and all are the shortest, with no waste in machining and cutting. Therefore, it is a high-efficiency, energy-saving transformer that uses traditional materials but operates with lower noise and a more compact structure. Its outstanding performance in reducing losses and saving materials fully aligns with China’s energy-saving policies.
