Abstract: The superconductor cable has many advantages, such as low line losses, large transmission capacity, small corridor occupation and great environmental friendliness, which can effectively improve the safety and stability of large-capacity power grids. The paper first introduces design thoughts, optimization methods and basic principles of the cold dielectric superconductor cable body. Then, taking the 110 kV/3 kA superconductor cable as an example, it optimizes structural parameters, winds the short sample of the cable and conducts AC and DC flow capacity tests under the low temperature @77 K to verify the rationality of this optimization design, which provides reference for the parameter design of superconductor cables with similar structure.
Key words: cold dielectric superconductor cable; structural design; laminar flow distribution
