建立了同轴多层电缆导体交流损耗和层间电流分布的解析模型。数值计算了层间电流分布和交流损耗，并评估了它们与电缆扭距和方向的关系。结果表明，当扭距大于200mm时，电缆的交流损耗和电流分布与扭距方向的关系不明显。结果表明，减小扭距小于150mm时，交流损耗减小，电流分布不均匀现象得到改善。
An analytical model to estimate the AC losses and the inter-layer current distributions of co-axial multi-layer cable conductors was developed. The inter-layer current distributions and the AC losses were numerically calculated and their dependence on the twist pitches and directions of the cables was evaluated. It was shown that when the twist pitches were longer than 200mm, the AC losses and the current distributions of the cables were not clearly dependent on the twist directions. It was also shown that the AC losses decreased and the uneven current distributions improved by decreasing the twist pitches less than 150mm.
