Abstract: A coil for a transformer includes first and second coil segments with each coil segment being defined by successive layers of wound conductor sheeting. The coil segments are electrically connected together and are adjacent, defining a space there-between. A plurality of cooling duct pairs are disposed between certain of the layers in each of the first and second coil segments such that, for each cooling duct pair, an end of a cooling duct disposed in the first coil segment is adjacent to an end of a cooling duct disposed in the second coil segment, with the ends being disposed in the space. A connector connects the adjacent ends of each pair of cooling ducts.

Abstract: A method provides a medium voltage radial drop winding for an open wound transformers. The method arranges a plurality of non-electrically conductive supports to extend outwardly from a periphery of an imaginary geometric shape so as to define an interior space. Each support includes a pair of opposing legs disposed in spaced relation and a bottom leg coupling the opposing legs to define at least one elongated slot between the opposing legs. Each slot has an open end. Conductive wire is dropped into the open end of each of the slots to substantially fill the slots and define at least one generally cylindrical winding segment carried by the supports.
