The cablesag caused by cable dead weight is vertical.
由钢索自重引起的垂度是竖向的。

These are prestress in cables, sag of cables, rise of arches, the vertical flexible stiffness of arches and the axial stiffness ratio between the cable and the arch.
这些参数为索预应力、索垂度、拱矢高、拱竖向抗弯刚度以及索和拱的轴向刚度比。

The dynamic voltage restorer is designed as unilateral energy flow equipment which can compensate continuous voltage sag or swell resulted from the voltage drop of power cable.
