以整跨导线作为研究对象，推导了短路情况下水平双分裂软导线的状态方程，得到了短路时导线的张力与变形，经实例计算证明所提出的方法比常用的计算方法更为合理。

In this paper, the state equation of horizontal double bundle flexible conductor during short-circuit is deduced through analyzing the whole span of the conductor. Furthermore, the short-circuit tension and deformation of the conductor are calculated by solving the state equation. Finally, examples are given to verify that the method presented in this paper is more reasonable than the conventional ones.
