The invention discloses a rectangular laminated type silicon steel iron core transformer. The rectangular laminated type silicon steel iron core transformer comprises an iron core and a coil; the iron core is formed by laminating rectangular silicon steel sheets and comprises a core column, an upper iron yoke and a lower iron yoke; the upper surface and the lower surface of the iron core are planes; the outer profile of the iron core is a cuboid; the section of the core column is a rectangle; and the coil is a square coil. In comparison with the prior art, the iron core is low in sheet shape, a belt material is convenient to shear and simple to produce, the effective space utilization rate of the iron core is high, a coil can be well supported, and the capability of resisting to sudden short circuit can be improved efficiently.
