Patent ID: 7439448

Claim:
A phase split structure of a multiphase superconducting cable, comprising: a plurality of cable cores having respective shield layers provided around respective superconductors, said shield layers each formed of a plurality of superconducting strands; a splitter box housing said plurality of cable cores extending from an assembly portion in which said cable cores are assembled into the superconducting cable, said cable cores in said splitter box being spaced apart from each other; an electrically-conductive connecting portion connecting respective shield layers of said plurality of cable cores to each other in said splitter box; and a holding tool separate from the splitter box and located within an interior of the splitter box housing and attached to the splitter box, for holding each of said plurality of cable cores at a constant distance with respect to each other for a portion of each of the cable cores that extends between the holding tool and a location in the splitter box where the cable cores exit the splitter box housing.
