摘要： 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.
