2UEW155 0.28mm Copper Enameled Winding Wire For Transformer/ Motor


0.28mm enameled wire is usually suitable for high frequency transformer windings. Due to its small diameter and good insulation properties, this enameled wire is ideally suited for use in the manufacture of high-frequency transformers. In high-frequency circuits, the insulating layer of enameled wire can effectively reduce current loss and magnetic coupling loss, and improve the efficiency and performance of the transformer.


Therefore, 0.28mm enameled wire can achieve better electrical characteristics and stability in high-frequency transformer windings, and is suitable for applications in various high-frequency electronic equipment and communication equipment.
