“…Owing to rapid development of manufacturing technology, high temperature superconducting (HTS) [1][2][3][4][5] coated conductors have the advantages of high critical magnetic field and strong current carrying capacity in high field magnets [6][7][8]. The conductor on round core (CORC) cable [9][10][11][12][13] wound by HTS tapes is considered as a good candidate for the central solenoid magnet of the tokamak device due to its isotropic infield performance [14], and low AC losses [15][16][17][18][19][20][21]. Tokamak systems that confine a plasma using magnetic fields is a promising way to achieve controllable nuclear fusion [22][23][24][25][26].…”

Due to the high isotropy and low AC losses, the multi-layer conductor on Round Core (CORC) cable is a good candidate for high field magnets, such as central solenoid magnets in fusion. Considering the difficulty in experimental measurement, numerical model is an effective way to illustrate the electromagnetic characteristics of the multi-layer CORC cable and provide further insights into its working performance. In this work, A 3D finite element model based on H formulation is proposed to simulate a CORC cable with as many as 18 layers considering electromagnetic coupling. The validity of the model has been verified by experimental results. Based on the proposed model, the DC transport current distribution characteristics and charge-discharge loss characteristics of multi-layer CORC cables wound in the same and opposite winding directions are investigated respectively. This work can provide an important reference for the design of multi-layer CORC cables for high-current or high-field application.
