In this paper, a geometric model of multi-core twisted wire is established to analyze the amplitude-frequency and angular-frequency characteristics of crosstalk in electromagnetic compatibility (EMC). The random combination of the cross-section of the multi-core twisted wire is used to accurately simulate the randomness of the actual multi-core twisted wire. The rotation transformation of the cross-section and the random transposition transformation between the conductors and the neural network model are used to obtain the per unit length (p.u.l) parameters at any position. And bring it into the method of chain parameters to find the crosstalk. The results show that the crosstalk amplitude-frequency and angular-frequency characteristics of the different cores of the multi-core twisted wire under the fixed model are very similar. Under the random model, the crosstalk of multi-core twisted wires is very close in the low frequency range, and satisfies a certain envelope value in the high frequency range. Through comparison with full-wave simulation, the reliability of the proposed method is proved.
