US Patent:

49809725, Jan 1, 1991

Filed:

Sep 11, 1989

Appl. No.:

7/405715

Inventors:

Sharad K. Singh - Pittsburgh PA
Donald T. Hackworth - Monroeville Boro PA

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

H01R 4300

US Classification:

29872

Abstract:

A cryogenically coolable inductive coil including: a multicomponent conductor comprising a plurality of components, each component including a cable of conductive material having a longitudinal axis about which the cable is twisted, the cable being wrapped helically and being compacted, after wrapping, to minimize voids in the cable and to give the component a polygonal profile, the components being disposed parallel, and adjacent, to one another with mutually facing sides of adjacent components being in contact with one another; and an electrical insulating and support structure at least partially surrounding the conductor for supporting stresses induced in the conductor due to magnetic fields created by the flow of current through the conductor, the conductor and the structure being wound to form the coil.
