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.
