Aiming at the complicated calculation of the current - carrying capacity of aluminum conductor alloy reinforced, a simplified method for calculating its current - carrying capacity is proposed. Firstly, the theoretical method for calculating the current - carrying capacity is studied, and the differences in current - carrying calculation are analyzed according to character- istics of aluminum conductor steel reinforced and aluminum conductor alloy reinforced. Then the simplified calculation method is proposed for the current - carrying capacity of aluminum conductor alloy reinforced, and the carrying - current capacity of an aluminum conductor alloy reinforced in different ambient temperature is calculated by the proposed simplified method. The test values are recorded and compared with the calculated values, and the reasons for the errors of simplified calculation method are analyzed. The test results show that the simplified method has small calculating work and the satisfied calculation accuracy for the engineering, which provides a reference for the current - carrying capacity analysis of aluminum conductor alloy rein- forced.
