Abstract

1449652 Making superconductive windings WESTINGHOUSE ELECTRIC CORP 5 Nov 1973 [16 Nov 1972] 51202/73 Heading B3A A method of fabricating an electrical superconductive winding 11 in a slotted structure includes forming a plurality of superconductive filaments 15 into a single strand, encasing the strand in a normally conductive material to form a wire 13, insulating the wire, covering the wire wire with a thermally responsive bonding material 21, forming a plurality of such wires into a composite cable, placing a desired number of coil turns of the cable in the slot and compressing the coil turns by a fluid pressurizing material 27 at a pressure sufficient to cause the bonding material 21 of adjacent wires to merge without filling the interstices among the wires, hardening the material 27 to keep the coils compressed and heating the structure to cure the bonding material 21 thereby securing the coil turns. The slotted structure may be a dynamoelectrical machine rotor or stator or an electromagnet. The wires 13 are comprised of niobium-titanium filaments 15, which are enclosed in a copper sheath 17 surrounded by an insulating layer 19, preferably of phenolic modified polyvinyl formal, and the bonding material 21 is an epoxy resin. The winding 11 is placed in a rotor slot, at the bottom of which is located a collapsible tube 25, and it is secured by a slot wedge 29. The pressurizing material 27 is forced into the tube, compressing the winding but leaving interstices 31 for the passage of a cryogenic refrigerant.
