摘　　要：弧垂张力特性是架空光缆设计的一个重要数据。然而文献中所列比载的计算公式只适合圆截面光缆的弧垂张力特性计算。对于8字形光缆那样的非圆截面光缆在冰载、风载等气象条件下的弧垂张力特性计算还未见报道。首次提出了8字形光缆的冰载、风载的计算公式,并采用双曲函数计算了8字形光缆的弧垂张力特性。Sag-tension characteristic is an important datum in the design of aerial fiber optic cable. However the formulas shown in literatures are suitable only for the calculation of sag-tension characteristic of fiber optic cables with round cross-section. And there is no any report to describe the calculation of sag-tension characteristic of figure-8 fiber optic cable under the climatic conditions of ice-load and wind-load. It is proposed for the first time the calculation formulas used for calculating ice-load and wind-load on figure-8 fiber optic cable, and calculated the sag-tension characteristic of figure-8 fiber optic cable using hyperbolic function.
