Abstract
Electrical apparatus includes electrical coil means formed of multiple turns of enamel-covered electrical wire axially mounted on a core of magnetic material in electromagnetic energy coupling relationship therewith, and a relatively flat flexible electrical cable containing a plurality of spaced parallel conductors extending between the cable ends contains a loop shaped portion extending about an axis of said core over an arcuate distance greater than 180 degrees. The method of adding a plurality of electrical windings to an electrical transformer of the type containing electrical coil means having a primary winding and at least one secondary winding, with said coil means having a central axis and a central passage coaxial with said axis; a core of magnetic material with said core having a portion extending through said central passage to support said coil means thereon, includes the step of forming into a loop extending about the axis of said coil an elongated flat cable of the type containing a plurality of spaced parallel electrical conductors insulated from one another.
