Numerical Simulation of Electromagnetic Properties of a CORC Cable with Reversal HTS Winding Tapes

High temperature superconducting conductor on round core (CORC) cable has superior mechanical properties and current carrying capacity. With the purpose of ensuring the safety and efficiency of CORC cable, the critical current and the AC loss should be considered when alternating current is applied on CORC cable. In this paper, the electromagnetic field of a high temperature superconducting CORC cable wound by six superconducting tapes with reversal winding is numerically calculated using the T-A formulation and FEM. Results indicate that the critical current is 1070 A, and the variation of AC loss according to applied current and self-magnitude is revealed.
