对于大型导管中电缆导体，线束之间的电流不平衡可能是直流和脉冲操作中性能降低的原因。研究了导线端部股线的电阻分布作为控制运行中电流分布的关键参数。采用Nb/SUB3/Sn线芯导线，由144根镀铬股线组成，制作了两个终端，其中一个终端填充了低阻焊料。将两种布局的电阻分布结果与在几个导体部分上进行的串接触计数的预期分布进行了比较。得出的结论是股间电阻的作用，以及连接附近的导体中可预期的电流不平衡程度。
For large cable-in-conduit conductors, a current unbalance among the strands may be the reason for reduced performance in both DC and pulsed operation. The resistance distribution of the strands at the conductor termination has been investigated as the key parameter controlling the current distribution in operation. A Nb/sub 3/Sn cable-in-conduit conductor consisting of 144 Cr plated strands has been used to prepare two terminations, one of them filled with low resistivity solder. The resistance distribution results for the two layouts are compared with the expected distribution from the count of the strand contacts, carried out on several conductor sections. Conclusions are drawn on the role of interstrand resistance and the degree of current unbalance that can be expected in the conductor next to the joint.
