Abstract
A method for producing superconductor wire characterized by forming a solid superconductor preform, suspending the preform within an oven such that a portion of it is heated to approximately its melting point, and drawing on the melted portion of the preform to form a superconductor wire. If the preform is solid, so is the drawn wire, and if the preform is hollow, the drawn wire becomes a capillary. Superconductor wires can be intertwined, or can be intertwined with ordinary conductive wires or non-conductive tubing to form superconductor cables. A superconductor transmission line is made by coating a copper tube with subsequent superconductor, insulating, and protective layers.
