[0020] As the Bi2212 superconducting material is expensive, the superconducting wire should be saved as much as possible during the stranding process. In the stranding process, copper wire is used to connect with it. In addition, the Bi2212 superconducting material is a ceramic material, which is relatively brittle. Excessive pulling force will cause the internal structure of the material to break and affect the performance of the material. During the stranding process, the tension will be strictly controlled.
[0021] Such as Figure 1-3 As shown, a method for manufacturing a cable made of high-temperature superconducting material includes the following steps:
[0022] Step 1: First use copper wire to connect with superconducting wire, and the outer diameter of the joint should be controlled within 2.0mm;
[0023] Step 2: First-level cable stranding, first twist the two superconductors on a single stranding machine. To ensure that the strands are not damaged during the stranding,...
