Abstract: Establishing three-dimensional simulation models of transmission towers rapidly is important for information management and analysis of the power grid. According to the structural characteristics of transmission towers, the tower is divided into several modules which have the similarity structure, and each module corresponds to a parametric three-dimensional model. Then modules are selected and assembled based on the type of tower and nominal height. By importing the parameters of modules into their parametric models, the three-dimensional model of various types and nominal heights of transmission towers can be completed quickly. Finally, the top structure of a cup shaped power transmission tower is used as an example to demonstrate this method. The 3D model can be established immediately only by inputting the type and nominal height of transmission tower. It is indicated that the parametric 3D modeling method for transmission towers is correct and practical.#br# Key words: power transmission tower; 3D modeling; parametric method; block
