Abstract

Due to the groove structure on the surface of outer wires, low wind pressure conductors have less resistance to wind. In this paper, the wind resistance coefficient of three different surface structure conductors are studied by the numerical simulation calculation method and wind tunnel test method. The results show that when the outer surface structure changes, the wind resistance coefficient of the conductor shows a significantly different trend when the wind speed increase. When the wind speed is more than 15m/s, the wind resistance coefficient of the conductors with groove surface decrease. Under the same condition of outer diameter and wind speed, the more grooves on the surface of the wire, the lower the coefficient. The conductor consisting of Z-shaped single wires with 20 concave arcs has the lowest coefficient at a wind speed of 30 m/s. The numerical simulation method can be used to design and optimize the structure of low wind-pressure conductors, which can improve efficiency and save costs.
