Abstract

See full text

A method provides a radial drop winding for an open wound transformer. A plurality of non-electrically conductive posts are arranged to define an interior space. Each post is of generally L-shape having a main body and a leg extending from a bottom end of the main body. During an open winding process, conductive wire is dropped to build up lengthwise along the posts to define at least one generally cylindrical winding segment supported by the legs of the posts.
