对考虑非线性E-J特性的电流分布进行了三维有限元分析。为了研究多层高温超导电缆的交流损耗，将超导绕带等效为具有各向异性导电率的导体，并采用周期性边界条件，大大缩小了分析范围。利用该模型，分析了绞距对带屏蔽层的多层高温超导电缆电流分布的影响，并对低交流损耗结构进行了讨论
3-D finite element analysis of current distribution taking account of the nonlinear E-J characteristic is carried out. In order to study the ac loss of multi-layered HTS power cable, the analysis region is considerably reduced by modeling spirally wound superconducting tapes as conductors having an anisotropic conductivity and using the periodic boundary condition. By using this model, the effect of the twist pitch on the current distribution of multi-layered HTS power cable with a shield layer is illustrated and the structure with low ac loss is discussed
