Abstract
A method for producing insulated superconductor wire including the steps of a tubular glass preform, filling it with a superconductor material, suspending the preform within an oven to heat a section of the preform to approximately its softening point, and drawing the softened preform into a superconductor wire. A plastic coating can be applied to the wire to increase its durability. The completed wire preferably includes a superconductor core having its superconductor phase aligned with the longitudinal axis of the wire, a glass coating over the superconductor core, and a plastic coating over the glass coating.
