In a stacked core () for a stationary induction apparatus according to an embodiment, joint surfaces where yoke portions () and leg portions () are joined have protrusions () formed from a plurality of magnetic members (), and recesses () formed from a plurality of magnetic members alternately, and the yoke portions and the leg portions are configured to be butted in such a form that the protrusions and the recesses mesh with each other, sheet-like magnetic insulators () are each disposed in a butt-joint portion between the protrusions and the recesses in such a form as to bend in a bellows shape along a butt line, and an air gap is provided, and in a relationship between the number of the stacked magnetic members forming each of the protrusions and the number of the stacked magnetic members forming each of the recesses, the number of the stacked magnetic members forming each of the protrusions is made smaller than the number of the stacked magnetic members forming each of the recesses corresponding to a thickness of the magnetic insulator.

Stacked core for stationary induction apparatus

A coil of an embodiment is formed by winding a winding conductor in which a conductive conductor is molded by a resin, wherein the winding conductor has the resin filled to a surface of the conductor without leaving any spaces.

Coil and method for manufacturing coil

A molded stationary induction apparatus is provided with: a winding the surface of which is covered with resin or an insulating material containing resin; a closed vessel in which the winding is housed and air having pressure exceeding atmospheric pressure is sealed; and a heat exchanger which cools the air in the closed vessel.
