1. The box-type transformer adopts the "eye" structure, the transformer is in the middle, the high and low voltage rooms are on both sides, and the center of gravity is in the middle, which is convenient for lifting;
2. The high-voltage side wiring is flexible, and vacuum load switch or oil-immersed load switch can be installed;
3. The structure is compact, the volume is only about 1/3 of the European transformer with the same capacity, and the weight is also greatly reduced.
