A low alternating current loss superconducting cable is provided, including a plurality of superconducting tapes spirally wound around a longitudinally extending core. The tapes are provided in a path between about 5째 and 85째 relative to the longitudinal axis of the core such that the tape completely covers the surface of the core. The tapes are generally parallel to each other and include first and second tapes that are adjacent to each other. The first and second tapes partially overlap each other.

The invention claimed is: 1. A low alternating current loss superconducting cable comprising a plurality of superconducting tapes arranged in a single layer and spirally wound around a longitudinally extending core in a path between about 5째 and 50째 relative to the longitudinal axis of the core, such that the tape completely covers the longitudinal surface of the core, the plurality of superconducting tapes being generally parallel to each other and including first and second superconducting tapes adjacent each other, the first and second superconducting tapes partially overlapping each other, the second superconducting tape having first and second continuous, straight lateral edges that are parallel to each other, the first straight lateral edge of the second superconducting tape overlying the first superconducting tape. 2. The cable of claim 1 wherein the superconducting tape is selected from a member of the group consisting of cuprate based, diboride based and metallic superconducting tapes. 3. The cable of claim 1 wherein the superconducting tape is a tape selected from the group consisting of monocore, multifilament, thin film, thick film, powder-in-tube and surface-coated superconducting tapes. 4. The cable of claim 1 wherein the superconducting tape is a tape selected from the group consisting of elliptical, and rectangular superconducting tapes. 5. The cable of claim 1 wherein the superconducting tape has a thickness of from about 0,001 mm to about 10 mm thick. 6. A low alternating current loss superconducting cable as in claim 1, wherein the plurality of superconductor tapes are spirally wound in a path between about 10째 and 30째 relative to the longitudinal axis of the core. 7. A low alternating current loss superconducting cable, comprising a plurality of superconductor tapes, each tape being individually positioned in a first layer around a longitudinal axis and extending longitudinally with said axis, each tape being located between two immediately adjacent tapes in said first layer and having first and second continuous, straight lateral edges parallel to each other, wherein the first straight lateral edge of each tape underlaps a first associated adjacent tape and the entire length of the second straight lateral edge of each said tape overlaps a second associated adjacent tape, such that at least a minor portion of the superconductive part of the superconductor tape underlaps or overlaps an associated adjacent tape. 8. A low alternating current loss superconducting cable comprising a plurality of superconducting tapes arranged in a singe layer and spirally wound around a longitudinally extending core in a path between about 5째 and 85째 relative to the longitudinal axis of the core such that the tape completely covers the longitudinal surface of the core, the plurality of superconducting tapes being generally parallel to each other and including first and second superconducting tapes adjacent each other, the first and second superconducting tapes partially overlapping each other at least 25%, the second superconducting tape having first and second continuous, straight lateral edges that are parallel to each other, the entire length of the first straight lateral edge of the second superconducting tape overlying the first superconducting tape. 9. A method of fabricating low current loss superconducting cables comprising winding a cable of superconducting tape around a core, where the superconducting cable comprises a plurality of superconductor tapes, individually positioning each tape in a first layer around a longitudinal axis and extending longitudinally with said axis, locating each tape between two immediately adjacent tapes in said first layer, each tape having first and second continuous, straight lateral edges parallel to each other, wherein the first straight lateral edge of each tape underlaps a first associated adjacent tape and the second straight lateral edge of each said tape overlaps a second associated adjacent tape, such that at least a minor portion of the superconductive part of the superconductor tape underlaps or overlaps an associated adjacent tape. 10. A three phase cable consisting of three low alternating current loss superconducting cables, such cable comprising a plurality of superconductor tapes, each tape being individually positioned in a first layer around a longitudinal axis and extending longitudinally with said axis, each tape being located between two immediately adjacent tapes in said first layer and having first and second continuous, straight lateral edges parallel to each other, wherein the first straight, lateral edge of each tape underlaps a first associated adjacent tape and the entire length of the second straight lateral edge of each said tape overlaps a second associated adjacent tape, such that at least a minor portion of the superconductive part of the superconductor tape underlaps or overlaps an associated adjacent tape.
