In order to reduce material costs of superconducting cables and construction costs when connecting these, this connection structure of a pair of superconducting cables (10A, 10B) has a cable core provided with a superconducting conductor layer (130) formed from a former (140) and multiple superconducting wires (100) arranged along the outer periphery of the former. The superconducting wires have a laminate structure comprising a base plate (1) and superconducting layer (3) formed on one primary surface of the base plate. In one of the superconducting cables (10B), a portion of the superconducting wires in the superconducting conductor layer are first superconducting wires, which are arranged in a state in which, relative to the base plate, the superconducting layer is positioned inwards in the radial direction of the cable core; in the other of the superconducting cables (10A), a portion of the superconducting wires in the superconducting conductor layer are second superconducting wires, which are arranged in a state in which, relative to the base plate, the superconducting layer is positioned outwards in the radial direction of the cable core. The one superconducting cable (10B) and the other superconducting cable (10A) are connected by the first superconducting wires and the second superconducting wires in a state in which the respective superconducting layers are opposed.

摘要:
Under compression by molds (31a, 31b), a wire (25), a covered area (27), and a crimping portion (5) are compressed and their cross-sectional areas decrease. Here, A1 is the cross-sectional area of the wire (25) after compression. That is, A1 is the sum of the cross-sectional area of the each strand after compression. Also, B1 is the cross-sectional area of the covered area (27) after compression. In the present invention, the compression rate for the wire (25) is set between 50 % and 80 %. Also, the compression rate for the covered area (27) is set between 40 % and 90 %. The amount of compression by the molds (31a, 31b) is set so that the compression rates are within these ranges. In the present invention, the compression rate is calculated by: (cross-sectional area after compression) / (cross-sectional area before compression). That is, 80 % compression rate means that the cross-sectional area has decreased by 20 % due to compression. That is, the relationships of 80 % ≥ (A1 / A0) ≥ 50 % and 90 % ≥ (B1 / B0) ≥ 40 % are satisfied.
