ABSTRACT:
An electrical inductive apparatus having a magnetic core with a rectangular core leg portion surrounded by a winding tube assembly around which is disposed a plurality of turns of an electrical conductor. The winding tube assembly consists of four members which interlock to form a rectangular opening around the core leg. Two of the members of the winding tube assembly, which are disposed adjacent the shorter dimension of the core leg, have a plano-convex cross-sectional configuration that resists movement of the electrical conductor along this axis of the core. A method of constructing an electrical winding for an electrical inductive apparatus having a rectangular core leg is disclosed.
