提出了一种确定输电线路弧垂和张力的新方法。该算法基于专门为传输线系统开发的新元素。这些元素使得可以在一般载荷、温度和蠕变历史下分析任何几何形状的线，无论是夹紧在使用条件下还是悬挂在施工滑轮中。由于这些元素源自真实的悬链线组件，因此结果（包括精确的剪切偏移和垂度修正）在任何地形中都保持有效。其中包含的示例提供了与传统分析方法的比较。
A new method for determining transmission line sags and tensions is proposed. The algorithm is based upon new elements developed explicitly for transmission line systems. These elements make it possible to analyze lines of any geometry under general loading, temperature, and creep history either clamped in the service condition or suspended in the construction sheaves. Because the elements are derived from true catenary components, the results, including exact clipping offsets and sag corrections, remain valid in any terrain. Examples are included that provide comparisons to traditional analysis methods.
