Abstract
A superconductive cable with a central superconductive conductor (1), a surrounding dielectric (3) and a surrounding superconductive return conductor (4). The central conductor (1) is formed from a single ribbon carrying superconductive material into a tube with a longitudinal extending slot (2) with the two edges of the ribbon abutting to each other. A ribbon (14) made of semiconductive material is wound around the central conductor (1) with at least one layer.
Claims5
A superconducting cable comprising:
- a central superconducting electrical conductor;
- a dielectric which surrounds said central conductor;
- and
- a superconductive return conductor which is arranged above said dielectric,
- wherein said central conductor is formed from a ribbon fitted with a superconductive material into an intrinsically stable tube having a slot which runs in the axial direction and at which the two edges of said ribbon abut to each other and wherein at least one additional layer of a ribbon of semiconductive material is wound around the central superconductive conductor, wherein said additional layer of a ribbon of semiconductive material is configured such that it protects the dielectric which surrounds the central superconductive conductor against damages from the edges and reduces dielectric problems that occur at said edges of said ribbon fitted with a superconducting material that rest on one another.
