Abstract
A distribution transformer (58) is assembled using a core (18) having a core surface (36) including an inner circumferential surface (40) defining an open eye region (38), an outer circumferential surface (42), and end surfaces (24, 26). Wedged-shaped core supports (20, 22), secured to the end surfaces of the core, are used to support the core during conductor winding operations and to mount the finished transformer within a transformer container (66). The core supports do not extend into the open eye region and allow virtually the entire inner circumferential surface to be covered by the electrical conductors (34, 56). The layers of electrical conductors are wound on top of one another so that each successive layer of electrical conductors conforms to the core surface and any previously wound conductors. Electrical insulation (54) is provided between each conductor layer.
