Abstract
The present invention relates to a combination twist structure of a superconducting cable core. The present invention relates to a new type of a combination twist structure of a superconducting cable core capable of accommodating the thermal contraction of the cable core in the longitudinal direction without having a space for accommodation, thereby capable of reducing an outer diameter of the superconducting cable, and eliminating the use of an additional equipment for forming the space for accommodation. The present invention provides a combination twist structure of a superconducting cable core formed by twisting a plurality of cable cores. The cable cores are combined by repeatedly changing a twist direction of the cable cores, and the contraction of the cable cores in the longitudinal direction is accommodated by untwisting the cable cores.
