By a method for constructing a superconducting multiphase cable comprising N phases, the phases are divided into n groups with N phases in each group, all the groups have a common screen. The individual groups may be geomtrically formed with coaxial or flat phases. The individual phases in each group may further be divided into individual conductors such as tapes. The insulation between the individual conductors in the groups may be separately insulated from each other or have a common insulation. In a particularly appropriate embodiment, the number of groups is 1 and implemented with a flat or concentric geometry. In this way, a compact superconducting power cable is provided, which is relatively inexpensive in production and has few working operations while maintaining good electrical properties.
A method for constructing a superconducting cable comprising N phases, the method comprising the steps of
A superconducting cable consisting of N phases, wherein each phase in the cable comprises a number of phase conductors, the phase-conductors having been classified into N-phase groups, each N-phase group comprising a phase conductor from each of the N-different phases, where N is greater than one, and wherein insulation means have been arranged in the cable around each phase conductor or between assemblies of phase conductors, and one or more of the N-phase groups or assemblies of N-phase groups has/have been provided with a common electrical screen.
