Transformers With Five Legs Cores

In many projects there is a need to adjust the dimensions of the transformer to the existing chamber of the machine. Construction of five-leg core reduces the height of the transformer. In the five-leg core there are two extra columns which connect the lower and upper yoke. The use of such a core in a three-phase transformer enable to reduce the cross section of yoke while the transformers power transformer and and column dimensions are unchanged.
