Abstract:
A process for manufacturing an electrical-power transformer, comprising:stacking a plurality of laminae to form a first, a second, and a third winding leg and an upper and a lower yoke; fixedly coupling the first, second, and third winding legs to the lower yoke; winding a first length of insulated conductive cabling on the first winding leg to form a first phase winding, winding a second length of the insulated conductive cabling on the second winding leg to form a second phase winding, and winding a third length of the insulated conductive cabling on the third winding leg to form a third phase winding after coupling the first, second, and third winding legs to the lower yoke; and fixedly coupling the first, second, and third winding legs to the upper yoke after forming the first, second, and third phase windings.
