摘要
按照输送容量的要求,介绍了220 kV某输电线路扩容改造工程中拟采用的3种导线,并根据具体工程情况分析了各自的利弊。通过综合比较,推荐采用铝包钢芯耐热铝合金导线,该导线具有良好的经济性和实用性。
Three conductor options,for the extension of 220kV Chengtian transmission line,are compared based on their conveying capacities,whose advantages and disadvantages are analyzed through practical situations.Finally,the heat-resistant aluminum clad steel stranded conductor is recommended,which is superior to other two options in economical efficiency and practicability.
