Innovative dc superconducting cables with higher current-carrying capacity than conventional cables were proposed in previous works. The superior property is brought about by the longitudinal magnetic field that enhances the critical current density. In this work, the current-carrying capacity of a three-layer cable composed of Bi-2223 tapes was(More)
The authors proposed an innovative superconducting dc power cable using the longitudinal magnetic field effect, i.e., a significant enhancement of the critical current density of a superconductor in a parallel magnetic field. It was expected that a cable with a high current-carrying capacity could be realized with(More)
Despite intensive research in the field of applied superconductivity, we only now start to use this phenomenon for the most obvious application, namely, power transmission. At present, there is an explicit shift from ac to dc high-temperature superconducting (HTS) cable systems due to the many advantages of dc. However, even with dc, a transmission line is(More)
We proposed the innovative force-free superconducting cable with higher current-carrying capacity than conventional superconducting DC cables utilizing the longitudinal magnetic field effect that enhances the critical current density. That is, the critical current density can be enhanced by the longitudinal magnetic field that the conductor itself and the(More)
The decreasing of critical current in the high-temperature tape superconductor (HTS) can be prevented by decreasing of the perpendicular component of self-magnetic field. The coating of this tape by the ferromagnetic material can deform the magnetic field around the HTS tape with flowing transport current. The present report contains the finite-element(More)
