PURPOSE:To facilitate to adjust the irregular end part of the winding and to prevent damages of an insulating layer in the case the winding end part is supported on the outer periphery of a core pusher via a ground insulator, by providing an insulating layer having shock absorbing and impregnating features in the inner periphery of the winding end part. CONSTITUTION:The core pusher 2 is provided at the end surface of a core 1, and the winding end part 4a is placed on the outer periphery of said core pusher 2 via the ground insulating layer 3 and the insulating layer 7. The insulating layer 7 comprises an insulating material 5 made of asbestos paper and the like having good flexibility and impregnating features, and glass tape 6. After bind 8 is wound around the outer periphery of the winding end part 4a, the entire product is immersed in a resin tank or the like and resin is impregnated. In this constitution, the irregularity at the winding end part 4a can be absorbed, damages on the insulators for the winding can be prevented, and the winding end part can be rigidly fixed. |
