摘要： A first flange and a second flange are superposed and fastened with a bolt and a nut in a fastening operation, to implement a fastening structure used at temperature lower than atmospheric temperature for the fastening operation. Assuming that the first flange has a thickness L1 and a coefficient of linear expansion α1, the second flange has a thickness L2 and a coefficient of linear expansion α2, superposed first flange and second flange have a thickness L, and the bolt has a coefficient of linear expansion α, a relation of L·α≧L1·α1+L2·α2 is satisfied, i.e. heat shrinkage of the bolt is not smaller than the total heat shrinkage of the first and second flanges. Thus, impairment of sealing property due to heat shrinkage is avoided at a flange junction used at low temperature.

摘要： A superconducting cable joint structure is a structure used to joint together superconducting cables used at cryogenic temperature or to joint together a terminal of the superconducting cable and a normal conducting cable, and it includes a joint insulation layer arranged radially outer than a portion connecting the superconducting cables' respective conductors together or the superconducting cable's conductor and the normal conducting cable's conductor together, and at least one coolant path provided at the joint insulation layer to cool the portion connecting the conductors together. The cable cores can have their connection prevented from generating heat to have an increased temperature.

摘要： A phase split structure of a superconducting cable includes three cable cores each having a shield layer provided around a superconductor, a splitter box housing the three cable cores extending from an assembly portion where the three cable cores are assembled into the cable, in a state in which the cable cores are spaced apart from each other, and a shield connecting portion connecting respective shield layers of the cable cores to each other within the splitter box. The shield connecting portion allows the cable cores to have their respective shield layers connected together with low resistance and each shield layer can pass a current substantially equal in magnitude to that which each superconductor passes. Thus in each shield layer a magnetic field can be formed having a level that can cancel a magnetic field generated from each superconductor. The structure can thus effectively prevent a large magnetic field external to the cable core.
