Superconductor cable, High temperature superconductor (HTS)
Power transmission cables, magnet conductors, data server centers, power distribution in microgrids, power transmission from alternative energy sources
The basic cable has a plurality of flat, tape-shaped ribbon superconductor wires assembled to form a stack having a rectangular cross section. The stack has a twist about the longitudinal axis of the stack. The wires are YBCO, BSCCO, or MgB2 tape conductors. The basic cables can be twisted together to form a larger cable that transmits higher electric current. The twisting is important in order to reduce undesired magnetic flux coupling between superconducting wires. The superconducting cable is disposed within and spaced apart from an electrical insulator, and the space between the cable and the insulator provides a channel for coolant. A cryostat surrounds the insulator to create a return coolant channel or a vacuum space for thermal insulation. There can be multiple sets of superconductors and insulators within one cryostat.
