Transformer lamination sizes.

We offer step lap and step lap lamination there has been a constant drive to reduce material and manufacturing costs in the design of distribution transformers. When considering the various material in a transformer of paramount importance is the overall cost of the core steel used. Standard laminations are described in din en 61021 in a variety of sizes and grades. These steel transformer laminations vary in thickness s from between 0 25mm to 0 5mm and as steel is a conductor the laminations are electrically insulated from each other by a very thin coating of insulating varnish or by the use of an oxide layer on the surface.

The ap is the product of the core window wa and the core cross sectional areas ac there is no need to calculate ap during your core selection process as the manufacturers publish. Within these main styles of bobbin wound laminated transformer other options are available subject to the size of the transformer and type of assembly. The stripwidth of the i bar d1 2e the laminations are stacked up to a thickness of e1 d and the length of the i bar l a d e and a are dimensions of the cut core. They are stamped from a pre material strip of the respective thickness and finished by a consequent annealing process to optimize the magnetic properties.

Ei lamination is made by the silicon steel strip the model of ei lamination in standard sizes is from ei 28 to ei 240 and the model of ei lamination in non standard sizes is from ei 36 to ei 360.
