Abstract

The Bi2212 cable-in-conduit conductor (CICC) is a composite soft material and is sensitive to stress-strain and brittle breakage. The cabling tensions are critical parameters for the CICCs and have undergone trial production many times to achieve effective cable control. Unreasonable tension will cause circumferential and axial motion, resulting in deflection bending, rotation fluctuations, and wire slip. This study investigated the manufacturing process of the Bi2212 CICC, optimizing the cable twisting process and reducing manufacturing consumption and damage. Additionally, optimized tensions of the Bi2212 CICCs during the cabling process, focusing on pay-off tension, rotation speeds, and traction tensions were presented. Finally, the results are tested and verified in the factory to examine the wire jumpers, serpentine bending, and pitch fluctuations. This research provides useful references for future cable fabrication of the HTS CICCs.

Bi2212 CICC 的制造工艺和布线优化

Bi2212 电缆导管（CICC）是一种复合软材料，对应力应变和脆性断裂非常敏感。电缆张力是 CICC 的关键参数，为实现有效的电缆控制，已进行了多次试制。不合理的张力会引起圆周和轴向运动，导致挠曲、旋转波动和滑丝。本研究调查了 Bi2212 CICC 的制造过程，优化了电缆扭转过程，降低了制造消耗和损坏。此外，还介绍了布线过程中 Bi2212 CICC 的优化张力，重点关注放线张力、旋转速度和牵引张力。最后，在工厂对结果进行了测试和验证，以检查跳线、蛇形弯曲和间距波动。这项研究为未来 HTS CICC 的电缆制造提供了有益的参考。

期刊介绍： Physica C (Superconductivity and its Applications) publishes peer-reviewed papers on novel developments in the field of superconductivity. Topics include discovery of new superconducting materials and elucidation of their mechanisms, physics of vortex matter, enhancement of critical properties of superconductors, identification of novel properties and processing methods that improve their performance and promote new routes to applications of superconductivity. The main goal of the journal is to publish: 1. Papers that substantially increase the understanding of the fundamental aspects and mechanisms of superconductivity and vortex matter through theoretical and experimental methods. 2. Papers that report on novel physical properties and processing of materials that substantially enhance their critical performance. 3. Papers that promote new or improved routes to applications of superconductivity and/or superconducting materials, and proof-of-concept novel proto-type superconducting devices. The editors of the journal will select papers that are well written and based on thorough research that provide truly novel insights.
