摘要：

Implement of low-resistive and compact terminal between superconducting cables and bus-bars is one of the most important challenges for industrial application of conductor on round core (CORC) cables. In this paper, a three-dimensional numericalmodel capable of simulating the terminal resistance and joint resistance of CORC cables is developed and validated by experimental data. On basis of this, the effect of different current injectionmethods on terminal resistance and the effect of trimming of HTS tapes on current distribution are discussed in this paper. Results shows a wide range of variation in terminal resistance and the homogeneity of current distribution. We expect conclusions obtained from this paper could provide guidelines for commercial and practical terminal fabrication of CORC cables.
