基于对铜、铝芯电缆技术、经济特性比较分析，认为铝芯电缆可靠性虽较铜芯电缆有所下降，但经济性优势明显，不失为现阶段降低电网建设成本的有效措施。总结了国内铝芯电缆应用现状，分析了其应用推广障碍，给出了江苏电网铝芯电缆应用建议。

It is shown from the economic and technical analyses of aluminum and copper core cable, that the reliability of aluminum core cable is lower than that of copper core cable. However, aluminum core cable is competitive in reducing the costs of power grid construction because it is cheaper than copper core cable. Therefore, the domestic application of aluminum core cable is reviewed, and the obstructions to popularize application are analyzed. Some constructive suggestions of aluminum core cable applied in Jiangsu electric power grid are proposed.
