The primary winding rack is comprised of a primary winding pipe, and each secondary winding rack is comprised of a secondary winding pipe; wherein the secondary winding pipe is installed horizontally, and the primary winding pipe is installed vertically, so that the thickness of the primary coil winding around the primary winding pipe along the horizontal direction is increased so as to reduce the thickness and volume of the transformer.
