As an important lifeline, regelation have a lot of serious effects to the transmission towers and transmission lines. China has been serious affected by the macroclimate, microtopography and microclimate condition, many accidents caused by ice cover occured frequently, it seriously impacted on people’s life and the development of social economy. In order to strengthen and improve the anti-icing capability of transmission tower-line system, it is necessary to study the iced transmission tower-line system. In this paper, the wire model, ground wire model and insulator model were established, and made a reasonable layout at the same time, then the coupled model of the transmission tower-line system is set up. It is supposed that the ice and transmission line are combined closely when there is no external loads, the ice is considered as circular cross-section, the composite structure of ice-transmission line is set up, then the coupled model of the composite structure-tower is set up, the dynamic characteristics of model can be obtained by the model analysis used the finite element analysis software SAP2000.
