    国内镀锌钢绞线标准对比

    Domestic Standards Comparison of Zinc-coated Steel Stranded Conductor

    • 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。

       

      Abstract: 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.
