“…In order to achieve large current-carrying capacity, parallel use of multiple tapes is indispensable. As a result, many second generation composite superconductor appeared, including twisted stacked tape cable [1][2][3][4][5], Roebel assembled coated conductor [6][7][8], quasi-isotropic strand [9][10][11], conductor on round core (CORC) [12,13] and so on. Among them, CORC cable has attracted wide attention because of its excellent performance, such as small cabling degradation and high current carrying density.…”

The conductor on round core (CORC) cable is considered as one of the best candidate cables for next generation fusion project due to its advantages of high current density, small cabling degradation and excellent magnetic ﬁeld performance. Nevertheless, the CORC cable will be aﬀected by huge transverse compression force during production and transportation, especially during operation in fusion project, which is the main reason that the current-carrying capacity of CORC cable will be irreversible degradation. There is little research on the transverse compression performance of CORC cables at present, and the inﬂuence rules of some cable parameters on its transverse compression performance are not clear yet. Therefore, in this paper, transverse compression tests are carried out on CORC cables of diﬀerent former sizes, materials and structure. The experimental results show that the larger the cable former size, the better its transverse compression performance. The transverse compression load limit of hollow tube former cable is larger than that of solid bar former cable. The performance of stainless steel bar former cable is similar to that of copper bar former cable. The limit value of transverse compression load of copper hollow tube former cable is larger than that of stainless steel hollow tube former cable. A 3D ﬁnite element model is also established to explain the internal reasons for the diﬀerences of current-carrying capacity decrease tendency of diﬀerent CORC cables. The research results can provide theoretical basis for the selection of former of CORC cable in the future. In addition, the inﬂuence of load block structure on the CORC cable’s transverse compression load limit is also studied in this paper. The results show that the arc block can signiﬁcantly increase the transverse compression load limit of CORC cable. The research results can provide a basis for the selection of the structure of support former when making cable in conduit conductor (CICC) and the structure of coil former when winding CORC coil magnet.

“…For cables based on coated conductors, this classification still holds but the situation is com-plicated by the intrinsic anisotropy of the ReBCO material and by the high aspect ratio of the strands [133]. For these reasons, authors often resort to numerical models to predict the loss in ReBCO cables [141,[207][208][209][210][211][212][213]. In this thesis however, we limit ourselves to analytical estimates, which are presented in Section 3.4 and compared to the measured data in Chapter 6.…”
