Abstract:
1. Superconductive electrical direct current cable comprising: a cryostat suitable for conducting a cooling agent made of at least one metal pipe surrounded by a circumferentially closed layer with thermal insulating properties; at least two superconductive conductors of different DC phases insulated relative to each other, are mounted in said cryostat; and a strand-shaped carrier of insulating material arranged within the cryostat has at least two helically extending grooves located diametrically opposite each other for insulating said at least two superconductive conductors of different DC phases, wherein the helically extending grooves are open outwardly, and in each groove is arranged one of the superconductive conductors, wherein each superconductive conductor is composed of a variably numbered plurality of superconductive elements.
