ABSTRACT:
The invention concerns a transformer lamination of the EI type, having a center leg, two outer legs and two yokes connecting these legs and having joints between one side of the center leg and between one side of the outer legs and the adjacent yoke for interleaving with a winding. The characteristic feature is that the width of the jointlessly connecting yoke is greater than that of the parted yoke, and that the width of the parted yoke and/or the width of the two outer legs is greater than half the center leg width.
