摘　　要：对目前国内常用的镀锌钢绞线标准进行对比分析,重点比较了各标准中对绞线结构、绞向和绞线节径比、绞制增量、绞线单位长度质量、绞线直流电阻、绞线综合拉断力等的要求。结果表明:GB/T 1179-2017覆盖了架空地线的常用规格,绞线参数合理准确,且增加了绞线直流电阻参数,方便用户根据不同需求选择合适型号规格的绞线。The mainly domestic standards of zinc-coated steel stranded conductor were compared and analyzed.The requirements of each standard,such as stranded conductor structure,direction and lay ratio of stranded conductor,stranding increment,mass per unit length of stranded conductor,direct-current resistance of stranded conductor and comprehensive tensile force of stranded conductor were compared.The results show that GB/T 1179-2017 covered the common specifications of overhead ground wire.The parameters of the stranded conductor were reasonable and accurate.The direct-current resistance parameters of the stranded conductor were added,which made it convenient for users to selected the appropriate type and specification of the stranded conductor according to different needs.
