Dry Type Cast Resin Transformer Core Distribution Transformer Stacked Silicon Steel

The coils can be installed on both sides of the core, so the number of turns of the transformer can be allocated to the two coils, so that the average turn length of each coil is shorter and the copper loss of the coil is reduced. In addition, if two coils that require symmetry are wound on two coils respectively, a completely symmetrical effect can be achieved. A set of silicon steel sheets composed of four C-type silicon steel sheets is called ED-type silicon steel sheets. The shape of the transformer made of ED-type silicon steel sheets is flat and wide. Under the same power conditions, the ED transformer is shorter than the CD transformer. Larger, in addition, because the coil is installed in the middle of the silicon steel sheet, there is an external magnetic circuit, so the magnetic leakage is small, and the overall interference is small. However, all the coils are wound on a wire package, which is thicker, so the average turn length is longer , The copper consumption is relatively large.
