Numerical Simulation of Drag Coefficients for Multi-Bundled Power Transmission Conductors

Article Preview

Abstract:

In this paper, the drag force of multi-bundled conductors in the flow of wind was analyzed. Numerical simulation of flow around power transmission multi-bundled conductors has been carried out. The drag force of power transmission lines ice-accreted/unaccreted in strong wind was investigated in detail. The drag total force coefficients and each line of the multi-bundled transmission lines were obtained and compared with the empirical results. This paper provided another more accurate method to get the drag force in the design of transmission lines.
