Abstract: In the variable frequency Alternating Current (AC) power system of large aircraft, it lacks the effective calculation methods for the analysis of wiring strategy of main feeder. In order to solve this problem, this paper studies the calculation method for adjacent factor. The AC resistances of two conductors of different materials, radiuses and center distances are calculated at wide frequency range. The new calculation formula has the advantages of simple form, clear physical meaning, wide application scope and high precision. A comparison with the analytical, finite element numerical and experimental calculation methods for the AC resistance of aviation cables verifies the correctness and effectiveness of the proposed method. The complicated procedure and time consumption of traditional finite element simulation tools are overcame. The method is applicable for engineering practice, and gives insights into calculation of AC resistance of wiring strategy of multiple conductors.
