Three-Dimensional Wound Core Distribution Transformer

The Three-Dimensional Wound Core Distribution Transformer represents a new generation of highly reliable transformer products featuring a more rational structure, superior performance, and lower manufacturing costs. This product breaks away from traditional planar designs by adopting a two-phase symmetrical three-dimensional structure. Furthermore, the absence of air gaps in its magnetic circuit ensures the magnetic flux direction of the silicon steel strips perfectly aligns with the magnetic path. The three core columns are arranged in an equilateral triangular configuration, resulting in identical and minimized magnetic circuit lengths. This design enables precise nesting during manufacturing with zero material waste.
