Claims

[Scope of utility model registration request]

(1) A winding in which a plurality of coils in which a conductor and an interlayer insulating material are wound in layers are laminated in the axial direction so as to maintain a predetermined insulation gap between the coils, and the winding is arranged in a predetermined angular direction on the outer circumferential side of the winding. A partial mold insulation part is cast and heat-hardened on the winding part in the angular direction, which includes a conductive connection part consisting of internal connection leads, external connection embedded terminals, etc. disposed in A molded winding for a stationary induction electric appliance, characterized by comprising a cover insulating part which is adhered to the inner and outer circumferential surfaces of the winding and heat-cured so that the directional ends overlap. , (2) Utility model registration Claim 1 In the utility model registration claim, the cover insulating part is a bulge or repreg sheet applied in advance so as to cover a predetermined angular range of the inner and outer circumferential surfaces of the winding, and A molded winding for a stationary induction electric appliance characterized by being heat-hardened together with a molded insulating part.
