Abstract: A transformer comprises at least a wound iron core, a lower portion clamp disposed at the lower portion of the wound iron core, and band for fastening the wound iron core and the lower portion clamp to each other. In the transformer, the lower portion clamp has a flat plate portion that supports the lower portion of the wound iron core and a bent portion that extends from the flat plate portion toward the outer periphery side of the wound iron core and upward. The end of the bent portion on the outer periphery side of the wound iron core extends to substantially the outer periphery of the wound iron core or to an outer side than the outer periphery of the wound iron core. The band fastens and fixes the wound iron core and the lower portion clamp to each other along the flat plate portion and bent portion of the lower portion clamp. This prevents the characteristics of the iron core from being deteriorated due to a compressive load applied to the iron core by the fastening of the band.

Abstract: Disclosed is a wound iron core (3) for a static apparatus in which magnetic paths in the inside of the wound iron core are subdivided to improve iron core characteristics. The iron core (3) is configured by using two or more kinds of magnetic materials (11 to 14) with different magnetic permeabilities to form laminated blocks with single plates or a plurality of laminated plates and by alternately arranging the laminated blocks with different magnetic permeabilities from the inner circumference.
