ABSTRACT:
A heat-distributing winding for the equalization of uneven heating of the winding parts of an annular core transformer including a winding concentric with the core and made from juxtaposed turns of wire-shaped heat-conducting material substantially perpendicular to and in heat-conductive contact with, but electrically insulated from the winding parts extending along the cylindrical external surface of the core and mainly in the generatrix direction of said core. The heat-distributing winding is applied to the inner side of or on either side of said above mentioned winding parts of the transformer and consists of turns electrically insulated from each other and consisting of wire of for instance rectangular cross-section.
