PURPOSE:To unnecessitate a panel supporting member by a method wherein, when a winding is constituted by lap-winding an insulating sheet and a metal sheet on the leg part of a core, a plurality of cooling panels to be interposed between windings are divided into four parts, an opposing pair of panels are arranged inside the metal sheet, the other pair of panels are arranged between the insulating sheet and the metal sheet, and they are connected respectively. CONSTITUTION:An internal winding 4 and an external winding 5 are constituted by lap-winding a metal sheet 2 and an insulating sheet 3 on the circumference of a core leg 1 through the intermediary of an insulating material. At this time, a plurality of cooling panels 6 are inserted between windings along the major axis of the core 1, and a liquid collecting tube 10 is connected to the panel 6 through the intermediary of an insulating pipe 11. At this time, the panels 6 are arranged as follows. Each panel is divided into four parts, a pair of opposing panels 6 are provided inside the insulating sheet 3 close to it, the other opposing pair of panels 6 are positioned between the metal sheet 2 and the insulating sheet 3, and they are connected by a support fitting 13. |
