、モールドブッシングを製造する。The molded bushing constructed as described above is manufactured by using an insulating member (C) made of insulating paper, synthetic fiber, glass fiber, etc. as an impregnation base material for one-layer insulation, and an electrode member (3) made of aluminum foil. are layered and wound alternately around the outer periphery of the center conductor (1) while maintaining a constant electrode thickness, that is, a distance between the electrodes, to form a capacitor core. Only the layers (or the first to third layers) constitute the capacitor core by further alternately winding the mixed paper electrode member (6) and the insulating member (k).This capacitor core is set in a mold. Then, the impregnated resin (ge) is vacuum impregnated and integrated to produce a molded bushing.

ない。In the molded bushing manufactured in this way, only the outermost two to three layers use the mixed paper electrode member (6), which requires impregnation with the impregnated resin (ge). During the vacuum impregnation treatment, the insulating member (2) and the electrode member (3) are well impregnated with the impregnating resin (4=) and integrated. For this reason, peeling or cracking at the interface of the electrode member (3), which conventionally occurs when aluminum foil is used as the outermost layer as the electrode member, does not occur, and the impregnating resin (4') is sufficiently impregnated. Therefore, no voids remain.
