QGDW 10632-2016 钢芯高导电率铝绞线简介：

QGDW 10632-2016《高压交流输电用钢芯高导电率铝绞线》是中国国家电网公司发布的一项关于高压交流输电线路用的导线技术标准。这种钢芯高导电率铝绞线（也称为GALC或钢芯铝合金绞线）是通过在铝绞线中加入一定比例的钢丝，形成钢芯铝合金复合材料，它结合了钢和铝的优点。

1. 高导电性：相比于传统铝线，钢芯高导电率铝绞线具有更高的导电性能，能减少输电过程中的电能损失。

2. 耐腐蚀性强：钢的添加提高了铝线的耐腐蚀性，尤其在恶劣的气候条件下，能够延长线路的使用寿命。

3. 强度高：钢的加入也提升了绞线的机械强度，可以承受更大的拉力和风压，适用于高海拔、高负荷的输电线路。

4. 质量轻：虽然钢芯铝合金绞线比纯铝线重，但相比钢芯钢绞线，其重量更轻，有利于减小输电线路的建设成本。

5. 抗蠕变性能好：铝线易发生热蠕变，钢芯的加入可以缓解这种问题，提高长期运行的可靠性。

总的来说，QGDW 10632-2016标准对钢芯高导电率铝绞线的尺寸、性能、制造和验收等细节做了详细规定，确保了其在高压输电线路中的安全稳定运行。
