提出了一种铝合金芯铝绞线载流量的计算方法。根据导线载流量的理论计算方法，分析钢芯铝绞线和铝合金芯铝绞线在载流量计算中的不同，提出了铝合金芯铝绞线载流量的简化算法。利用该算法计算了某型号铝合金芯铝绞线在不同环境温度下的载流量，然后对该导线进行载流量试验，对比计算值与实测值，分析简化计算法的误差。结果表明，该简化算法计算量小且计算精度满足工程要求，可以为铝合金芯铝绞线载流量的分析提供参考。%The paper proposed a simplified method for calculating the current-carrying capacity of aluminum alloy core aluminum stranded conductor. It is studied the theoretical method for calculating the current-carrying capacity of the wire, the differences in current-carrying calculation is analyzed, it proposed the calculation method for current-carrying of aluminum alloy core aluminum stranded conductor can be simplified. And the method is used to calculate some aluminum alloy core aluminum stranded in different ambient temperature, then the experiment of current-carrying capacity on the wire is done, it compared the calculated value and ex￣perimental value, it analyzed the reasons of errors of simplified calculation method. The experimental results show that the simplified method amount of calculation is significantly reduced, and the calculation accuracy, meeting the requirements of engineering, which can be a reference for the current-carrying capacity analysis of aluminum alloy core aluminum stranded conductor.
