Study on Windage Yaw of Ceramic Suspension String

The windage yaw of suspension string under dynamic wind was analyzed with the method of finite element (FEM). By using finite element software ABAQUS, the windage yaw angle of suspension string under gust and pulsating wind for 500kV high voltage transmission line was also computed and compared with the result calculated by traditional statics method, it clearly shows that the windage yaw angles of suspended under those two kinds of dynamic winds are larger than those determined by existing design discipline of high voltage transmission line, which may be one of the reasons for flashover caused by windage yaw happening frequently.
