High-Temperature Superconducting High-Current Cables

A high-temperature superconducting (HTS) device comprising:

• a cable subassembly with a cross section having a cable subassembly width and a cable subassembly thickness further comprising:
• a plurality of tapes formed of a superconducting material, each of the plurality of tapes having a tape length, a first face and an opposing second face of a tape width, and a first edge and a second edge having a tape thickness;
• and
• a cable subassembly wrapper formed of a first non-superconducting material disposed around a stack of the plurality of tapes;
• wherein the plurality of tapes in the stack are slidably arranged face-to-face with aligned first and second edges, the stack of tapes having an aggregate thickness substantially equal to the cable subassembly width less the thickness of the cable subassembly wrapper, the tape width being substantially equal to the cable subassembly width less the thickness of the cable subassembly wrapper, the stack of tapes is not substantially twisted around a longitudinal axis of the stack of tapes, the cable subassembly has a subassembly length substantially equal to the tape length, and the subassembly wrapper is disposed around the cable subassembly for substantially the length of the cable subassembly.
