ABSTRACT:
Improved end clamping members are used in transformers having a horizontal magnetic circuit which is preferably of rectangular cross-section.
Each end clamping member is embodied by juxtaposed longitudinal beams--side beams (4) comprising magnetic laminations on edge over substantially their whole thickness, and intermediate beams (5) comprising magnetic laminations on edge over only some of their thickness, the end clamping member being embodied for the rest by a longitudinal flat iron member (15), and each group or set of magnetic laminations has at its center the longitudinally extending wedge-shaped member and on each side another longitudinally extending flat iron member of the same width.
The invention is of use more particularly for high-power shell type transformers in a form-fit tank.
