耐热导线与钢芯铝绞线在线路增容改造中的可行性分析

The Feasibility Analysis of the Heat Resistance Wire and ACSR in Power Compatibilization

耐热铝合金导线具有耐高温运行、输送容量大、经济性能优越等特点,输送容量是同截面普通导线的2倍,能大大节约材料,是城乡电网改造工程选用的最佳材料之一。钢芯铝绞线可以通过提高运行温度增大输送容量。文章对耐热导线及钢芯铝绞线在旧线路增容改造中的可行性进行了分析,对旧线路增容改造提出了建议。

The heat resistant aluminum alloy conductor with high temperature operation, high transmission capacity, and superior economical efficiency. The transmission capacity is twice of normal conductor with the same cross-section, and it could save lots of materials, especially to save the limited land resources, which has become one of the best material choices in the projects for upgrading urban and rural power grids. ACSR can improve operational tempcrature by increase the transmission capacity. In this paper, the feasibility of the heat-resistant wire and ACSR in power compatibilization is analyzed, compatibilization of the old electric line is recommended.
