[0002] The oil-immersed transformer is a new type of high-performance transformer with a more reasonable structure and better performance. Its three-dimensional wound core has three core columns arranged in an equilateral triangle, with no air gap in the magnetic circuit and tighter winding. During the installation process, the oil-immersed transformer needs to be assembled and fixed by installing components to meet the needs of long-term and stable operation of the oil-immersed transformer.
