Research on Contact Simulation of Strands in Large Cross-Section ACSR

In the process of tension stringing, conductor withstands the action of axial tension and torsion. In order to study the contact force between strands of cross-section ACSR after loading, the equivalent stress and contact results of 1250 mm2 ACSR under different loads combined by axial tension and tension-torsion are analyzed by finite element method. The results show that the steel core of the conductor bears the main stress, and the stress distribution of the same layer strand is basically the same; the maximum contact force between the strands of each layer appears near the middle section of conductor, and the maximum contact force occurs between steel strand and steel strand.
