This paper presents the alternating current (AC) loss analysis on high-temperature superconductor (HTS) Cross-Conductor (CroCo) cables, in order to evaluate whether they could be utilized for electrical power transmission. The modeling of HTS CroCo cables was based on a cable assembled at the Karlsruhe Institute of Technology (KIT) and the AC loss calculation was based on the H-formulation model implemented in the finite-element method (FEM) software package COMSOL Multiphysics. The AC loss calculations have been carried out for isolated single-phase CroCo cable and three-phase CroCo cables. The AC loss angular dependence of a particular phase of CroCo cables during three-phase operation has been studied. The current distributions of individual tapes within CroCo cables have been investigated. Index Terms-HTS cross-conductor cable, AC loss, power transmission, finite element analysis. b c c c k J B J

“…It has been proposed to construct a large current capacity CIC conductor by assembling a number of TSTC wires. Similar conductors based on this TSTC structure have been proposed, including RSCCT conductors from SPC in Switzerland [4], Slotted CIC conductors from ENEA in Italy [5], CroCo conductors from KIT in Germany [6], and QI conductors from North China Power University (NCEPU) in China [7]. CORC (Conductor on Round Core) conductor is commercialized by Advances Conductor Technologies LLC of the United States [8].…”

Development of FAIR conductor and HTS coil for fusion experimental device

et al. 2020

This study is aimed at the development of high-temperature superconducting (HTS) magnets for application in a fusion experimental device next to the Large Helical Device (LHD). By applying the features of an HTS, high current density and high stability can be balanced. As a candidate conductor, REBCO tapes and pure aluminum sheets are laminated and placed in the groove of an aluminum alloy jacket with a circular cross-section, after joining a lid to the jacket using friction stir welding, and twisting the conductor to homogenize its electrical and mechanical properties. The FAIR conductor derives its name from the processes and materials used in its development: Friction stir welding, an Aluminum alloy jacket, Indirect cooling, and REBCO tapes. Initially, the degradation of the critical current of the FAIR conductor is observed, which was eventually resolved. The development status of the FAIR conductor has been reported.

“…In recent years, second generation high-temperature superconductor (HTS) rare-earth barium-copper-oxide (REBCO) tapes have been widely used for high-current cables, such as round core cable [1], Roebel cable [2], and twisted stacked-tape cable [3]. CrossConductor (CroCo) cable is one of the twisted stacked-tape cables, and has the capability to achieve a high current density [4]. CroCo cable offers good mechanical performance because it can relax stresses from twisting and bending process, and increase the possibility for construction of long-length cables [4].…”

This paper demonstrates the alternating current (AC) loss analysis on HTS CrossConductor (CroCo) cables, which could be potentially used for electrical power transmission. The modeling of HTS CroCo cables and AC loss calculation were based on H-formulation model using FEM package COMSOL Multiphysics. The AC loss calculations have been carried out for isolated single-phase CroCo cable and three-phase CroCo cables respectively.
