Patent ID: 7265297

Claim:
A multiphase superconducting cable connection structure comprising: a pair of multiphase superconducting cables each including a plurality of cable cores that each have a superconductor; a connection box accommodating a plurality of conductor connects, each of the plurality of conductor connects connecting a superconductor of a corresponding cable core of the plurality of cable cores of one of the pair of multiphase superconducting cables to a superconductor of a corresponding cable core of the plurality of cable cores of another one of the pair of multiphase superconducting cables; a plurality of solid insulation members, each solid insulation member of the plurality of solid insulation members fixed to an outer circumference of a corresponding conductor connect of said plurality of conductor connects; and a metal flange fixing the plurality of solid insulation members to said connection box; wherein each cable core of the plurality of cable cores of the one of the pair of multiphase superconducting cables includes a shield layer surrounding said superconductor of the cable core; wherein the multiphase superconducting cable connection structure further includes a shield connect provided to short circuit shield layers of at least two cable cores of the plurality of cable cores of the one of the pair of multiphase superconducting cables; and wherein the shield connect is formed of an element different from said shield layers of said at least two cable cores.
