Claims (1)
なる多重筒状巻線を鉄心に設けた変圧器において
、前記層間絶縁物を巻線端部から所定長延出させ
、その延出部分を互に他の層のそれと部分的に重
合するように放射状に折曲することにより階段状
表面部を有する端部絶縁物層を形成したことを特
徴とする変圧器。 In a transformer in which a core is provided with multiple cylindrical windings wound in multiple layers with an interlayer insulator interposed between each layer, the interlayer insulator is extended a predetermined length from the end of the winding, and the extended portion is 1. A transformer characterized in that an end insulating layer having a step-like surface portion is formed by radially bending each layer so as to partially overlap with that of the other layer.
