The conventional transformer core is generally made of silicon steel sheet. The silicon steel is a silicon-containing steel, and the silicon content is 0.8-4.8%.

The straight joint is formed by splicing six rectangular laminations into a layer of iron core sheet, as shown in figure 3, and has the characteristics of convenient processing, easy lamination, high structural strength, strong shaping and the like. However, the existing single layer with straight seams has the disadvantages of relatively large number of laminations, relatively slow lamination speed, low production efficiency and urgent need for improvement, and therefore, the utility model provides a novel high-efficiency iron core.
