Silicon Steel Three-Dimensional Wound Core Transformer
The core employs high-efficiency, low-loss, high-permeability, heat-resistant notched silicon steel sheets wound into a three-phase independent framework structure. The core magnetization direction is aligned with the rolling direction of the silicon steel sheets, ensuring uniform magnetic flux distribution throughout the magnetic circuit, without obvious high-resistance zones or magnetic flux distortion at seams. It features low no-load loss and low noise.
The three-dimensional wound core transformer is an energy-saving power transformer that innovatively reforms the laminated magnetic circuit structure and three-phase layout of traditional power transformers. Compared to traditional transformer cores, it offers:
