In order to study the effect of multi-dimensional structural parameters on the inter-layer current distribution of three-phase turnkey superconducting cable, this paper takes 35kV/2kA three-phase turnkey high-temperature superconducting cable as the research object, and uses the equivalent circuit model to solve the inter-layer current distribution. Through the analysis results, it is concluded that the variation of inter-layer current is related to structural parameters such as winding radius, winding angle and winding direction, in order to obtain uniform inter-layer current distribution, it is necessary to use the opposite direction of neighboring layers, and at the same time, try to ensure that the winding angle of each layer is similar to. These conclusions can be used as a reference for the design of better performance of the cable structure.
