Reference numeral 10 denotes a transformer winding, which is constructed by laminating plate-like coils (not shown) wound in a rectangular shape as shown in FIG. > The magnetic core 20.20 of the transformer, which has a structure in which the opposite sides 11.11 are provided with a transformer magnetic core 20.20 forming a magnetic path, has conventionally been made of silicon steel plate. It is made by layering! Since a Jt layer core is used, it is possible to reduce the loss by constructing the core with a thin magnetic material such as a strong and flexible amorphous magnetic material. When winding it around the wire 10, since the side 1A of the laminate 1 and the cross section of one person are square, an unreasonable force is applied to the part of the thin magnetic material that corresponds to the corner IR, causing it to break from this part. There was a problem that it was easy to break, did not break, and iron loss increased due to the attempt.

After installation, wrap a thin @GL Aiki 140.40 on top. As a result, the magnetic core 50.50 is not in direct contact with the transformer winding a30, so the insulation is higher than that in Figure 3.
A higher cooling effect can be obtained than the one shown in the figure.

When working with a thin magnetic material,
There is no risk of breakage due to the application of large tension locally, and the winding can be done while applying constant tension at all times.
