摘要：

The paper reviews some recent results of the authors' research group related to the modeling of the hysteretic behaviour of metallic stranded cables and applies them to the definition of a theoretical model for the self-damping of a widespread typology of overhead electrical line conductors, namely the ACSR conductors. Closed-form expressions of the dissipated power per unit of length of the conductor, previously derived by the authors, are cast in a new form that allows for a more effective comparison with available experimental data of the literature.
