ADSS 结构光缆结构设计与计算工艺摘 要:从 ADSS 光缆的结构特点入手,分析了光纤余长和抗张元件在 ADSS 光缆设计中的重要地位,详细阐述了层绞式ADSS 光缆中绞合余长的产生机理和控制方法以及加强元件芳纶纱的选取原则和求解过程,并提出了 ADSS 光缆的发展方向和开发前景。我国的电力输电线路总长度排名世界第二。据统计，现有的 110KV 及以上线路就有 31 万公里，还有大量的 35KV/10KV 老线路。虽然近年来国内 OPGW 需求量急剧增加，ADSS 光缆的需求量仍是稳中有升。 关键词: ADSS 光缆;光纤余长;芳纶纱Design and calculation of the structure of ADSS structureAbstract: from the structure characteristics of ADSS optical cable, optical fiber is analyzed Yu Changhe tensile element in the important position of ADSS cable design, in detail elaborated the gysts stranded ADSS cable in yu long mechanism and control methods and strengthening element of aramid yarn selection principle and solving process, and put forward the development direction of ADSS cable and development 1prospects. China has the second largest power transmission line in the world. According to statistics, there are 310,000 kilometers of existing 110KV and above, and a large number of 35KV/10KV old line. Although the demand for OPGW has increased sharply in recent years, the demand for ADSS optical fiber is still rising.Key words: ADSS optical cable; Fiber length; Aramid yarn0 引言随着信息技术的高速发展,电力系统使用光纤通信技术日益增多。在电力通信网从主干线到接入网大面积光纤化的进程中,电力特种光缆的作用是无可替代的。如今广泛应用的电力特种光缆主要有两种:光纤复合架空地线 OPGW 和全介质自承式光缆 ADSS,其中 ADSS 光缆以其优越的性能价格比成为旧电力线路改造和农用电力通信线路建设中的首选。1 ADSS 光缆简介ADSS 光缆对老线路是一种“添加物”，ADSS 光缆只2能尽量去适应原有的线路条件，这些条件包括(但不限于)气象负载、杆塔强度和形状、原有导线的相序排列和直径、弧垂张力和跨距及安全间距等。虽然 ADSS 光缆外...
