A like-CORC based on the Quasi-isotropic (Q-IS) conductor, so called Q-IS_CORC consisting of CORC and Q-IS making from 2 G high temperature superconducting (HTS) tapes, is investigated in terms of AC losses by combining experimental with numerical methods. A new type of a like-CORC conductor is presented and is good bending performance as well as easy to manufacture in long lengths. Moreover, this paper focuses on understanding its influence on AC losses and provides a method for reducing the AC losses. A novelty of this paper is the use of a new T-A formulation (Accelerated T-A formulation), which, for the first time, is employed for 3D modeling of CORC cable and used to study AC losses. The influence of twisting on AC losses was verified by simulation. Then, the optimal pitch length is found to reduce AC losses.

通过结合2G高温超导（HTS）胶带，研究了基于准各向同性（Q-IS）导体的相似CORC，即所谓的Q-IS_CORC，由CORC和Q-IS组成，由2 G高温超导（HTS）胶带制成用数值方法进行实验。提出了一种新型的类似CORC的导体，该导体具有良好的弯曲性能以及易于长距离制造。此外，本文着重于了解其对交流损耗的影响，并提供了一种减少交流损耗的方法。本文的新颖之处在于使用了新的TA配方（加速TA配方），该配方首次用于CORC电缆的3D建模并用于研究AC损耗。通过仿真验证了扭曲对交流损耗的影响。然后，找到最佳螺距长度以减少交流损耗。
