Dynamics characteristic of composite insulators under horizontal load caused by wind load is studied in this paper. For the advantages, V-string insulators are widely used in overhead transmission lines. Earlier study proves that the buckling deformation of the composite insulator under compression load is stable. So it is reasonable to allow composite insulators bearing compression force. The new concept makes it possible to adopt smaller V-string included angle and reduce the costs of the overhead transmission line. The static loading characteristics of V-string at different included angle under different vertical and horizontal load have been determined in the V-string static load experiments. The possibility of adopting small included angle is verified. Because of the differences between dynamic wind load and static load, in certain circumstances, the dynamic effects need to be examined. Dynamics response of insulator-conductor system is analyzed in the paper. The mathematical model of the insulator-conductor system is presented. Finally, according to the experiment and simulation results and the theoretical analysis, the complete optimized designing solution of V-string composite insulators for 330 kV overhead transmission line is determined.
