型线同心绞架空导线的结构设计

Constructional Design of Concentric-Lay-Stranded Formed Wire Overhead Conductors

型线同心绞架空导线与圆线同心绞架空导线相比,具有更大的导体截面利用率,在相同截面积条件下,具有直径小、风载低、耐腐蚀、自阻尼性优等众多优点,在架空输电线路上的应用将越来越广泛。该文主要对该产品的结构设计作一探讨。

Compared with the concentric-lay-stranded round wire conductors,the concentric-lay-stranded formed wire conductors feature greater cross-sectional utilization.With the same cross-section,formed wire conductors have smal-ler diameter,lower wind load,better corrosion resistance and improved self-damping characteristic.These conductors will find wider and wider application in overhead transmission lines.This paper investigates the constructional design of concentric-lay-stranded formed wire overhead conductors.
