For self-shielded HTS DC cable, fault current characteristics is an urgent research domain. Since the use of parallel conductors a common method to protect tapes, REBCO tape in with several different metal materials are analyzed this paper. The stainless steel designed into cable for its ascendant limiting ability. Then 2D simulation model established based on coupling electric, magnetic and thermal fields simulate current-temperature variations cables. At last, influence thickness variation...
The critical current of a REBCO tape is crucial factor in describing its quality. orientation applied field has significant impact on it which different under temperatures and amplitudes field.

This paper presents a new method to improve both the critical current and uniformity of distribution in high-temperature superconducting (HTS) cable. The proposed involves weaving cable using transpositional REBCO tapes. To establish three-dimensional (3D) finite element model (FEM) approach, H formula is used. Numerical methods are used analyze at 77 K. <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">E</i> -...
In practical applications, the stacking pattern of superconducting tapes has vital influence on loss and current quality conductors during transmission. Based structure quasi-isotropic strand (Q-IS), distribution magnetic field at ends is simulated measured. order to investigate distinction for different structures, a kind made by REBCO coated (CC) only (Q-IS1), other stacked copper CCs alternately (Q-IS2) are studied. Results show that Q-IS1 better transfer performance.
