Abstract

The critical currents of a twisted single-tape were measured at 4.2 K in fields up to 17 T. It was confirmed that the critical current of a twisted-tape was similar to that of a flat tape in c-axis fields. Based on the single-tape critical-currents, a 40-tape (4-mm width) twisted stacked-tape cable (TSTC) conductor was experimentally evaluated at fields up to 17 T at 4.2 K. It was found that the Lorentz load degradation of the TSTC conductor was negligible at the end of a cyclic test. The TSTC cabling method has been considered to be suitable for developing a high-field high-current REBCO conductor for magnet applications as well as power transmission cables. A method to fabricate the inner legs of a D-shape toroidal field coil using a TSTC conductor has been discussed. This method allows the conductor to properly resist the transverse Lorentz load and mitigate ac loss issues by adopting a parallel-HTS-tape flat cable configuration where necessary.

Self-field measurements of an HTS twisted stacked-tape cable conductor

Dataset Obana, T. ; Terazaki, Y. ; Yanagi, N. ; ...

For a twisted stacked-tape cable (TSTC) conductor composed of REBCO tapes, self-field measurements were conducted with Hall sensors. In the measurements, a 650 mm diameter single turn coil wound with the TSTC conductor, which was made with 48 REBCO tapes whose width was 6 mm, was utilized as a test sample. Based on the measurement results, the current distribution of the TSTC conductor was investigated with analytical models. The analytical results indicate the current distribution of the TSTC is uniform under the condition that the operating current is 10 kA and the sample temperature is approximately 30 K.

Termination Methods for REBCO Tape High-Current Cable Conductors

Dataset Takayasu, M. ; Chiesa, L. ; Minervini, J. V.

Three types of joint termination methods for a 2G HTS cable have been developed: YBCO-BSCCO, YBCO-YBCO, and Folding-fan soldered terminations. For the YBCO-BSCCO terminator, each YBCO tape of a cable is connected to a BSCCO tape while the other ends of BSCCO tapes are bundled together and soldered inside a copper tube. The same termination was tested more than 30 times in liquid nitrogen and helium without any problems. It was operated at 10 kA in liquid helium and more than 2 kA in liquid nitrogen. The YBCO-BSCCO termination has been confirmed to be very easy to fabricate and convenientmore »« less

Low-field-orientation effect on REBCO tape performance and its power cable application

Dataset Takayasu, Makoto ; Chiesa, Luisa ; Minervini, Joseph V.

Low field characteristics, including field orientation dependence relations for four different commercially available REBCO tapes, were investigated in an external field of up to 0.3 T at 77 K. A design method of the performance of a twisted stacked-tape conductor (TSTC) has been developed for a power transmission line. Cable critical current is obtained from an averaged self-field distributed over the cable cross section and the minimum critical current obtained from the field orientation dependence in transverse fields experimentally measured for the single tapes. The performance of three types of TSTCs, i.e., single-, double-, and triple-channel configurations, has been assessedmore » for the four REBCO tapes.« less
