Abstract
Conductor on round core (CORC) cable is made of second-generation high-temperature superconducting (HTS) tapes wound in multi-layer spirals. It is the most promising HTS cable due to its simple preparation process, high current-carrying capacity and low AC loss. CORC cable has shielding currents that cause field errors and centre magnetic field drift during electromagnetic field loading. Additionally, small changes in the winding mode and winding angle of the tape will lead to changes in the current distribution on the ReBCO tape, which results in differences in AC loss. In this paper, the influence of shielding on the electromagnetic characteristics and central magnetic field of CORC cable is discussed, and the influence of different winding modes and angles on the magnetization loss is investigated. The results of the study show that the shielding current will cause magnetization loss, and the winding structure has a significant effect on these losses. Adjusting the winding angle can reduce the magnetization loss and improve the cable performance.
期刊介绍:
Physica C (Superconductivity and its Applications) publishes peer-reviewed papers on novel developments in the field of superconductivity. Topics include discovery of new superconducting materials and elucidation of their mechanisms, physics of vortex matter, enhancement of critical properties of superconductors, identification of novel properties and processing methods that improve their performance and promote new routes to applications of superconductivity.
The main goal of the journal is to publish:
1. Papers that substantially increase the understanding of the fundamental aspects and mechanisms of superconductivity and vortex matter through theoretical and experimental methods.
2. Papers that report on novel physical properties and processing of materials that substantially enhance their critical performance.
3. Papers that promote new or improved routes to applications of superconductivity and/or superconducting materials, and proof-of-concept novel proto-type superconducting devices.
The editors of the journal will select papers that are well written and based on thorough research that provide truly novel insights.
