Abstract

The aerodynamic characteristic parameters are the foundation of vibration analysis of the overhead conductors. In this paper, a typical overhead conductor is studied using computational fluid dynamics (CFD) method. The smooth wire model and rough wire model are established, respectively, and the experimental analysis is carried out in the numerical wind tunnel. The aerodynamic parameters are obtained, and the influence of roughness of the wire surface is investigated.
