Superconducting cable system

In an embodiment, an apparatus including a cable (110,210,310,410) is disclosed. The cable (110) includes at least two conductors (121,122), each conductor (121,122) comprising a high-temperature superconductor material, wherein a first conductor (121) is concentric within a second conductor (122), and wherein the first conductor (121) is tapered at a first end (130) of the cable (110) and the second conductor (122) is tapered at a second end (135) of the cable (110).
