Dynamic Response of Conductor Breakage for Oxytropis Transmission Tower-Line System
Applied Mechanics and Materials, 2010Dynamic response of conductor breakage is analyzed on guyed oxytropis transmission tower-line system of 500KV 5291 JinJiang-Zhenjiang lines. Considering unbalanced tension, finite element method is presented. Result of the transient analysis shows that the vibration of tower-line system happens after conductor breakage.

Seismic responses of transmission tower-line system under multi-component ground motions
Advances in Structural Engineering, 2023In this study, shaking table tests, theoretical research, and finite element modeling analysis were conducted on seismic responses of a transmission tower-line system under multi-component ground motions. The rocking component of ground motion was determined from the original seismic record by the wavelet analysis.

Dynamic Behavior of Transmission Tower-Line Systems Subjected to Insulator Breakage
International Journal of Structural Stability and Dynamics, 2018Ice loads attached to a transmission tower-line system can not only increase the vertical loads on the insulators, but also cause flashover to occur more easily. Both effects can lead to an increased probability of insulator breakage. In this paper, a finite-element model of a transmission tower-line system with three towers and four span lines under ...

Wind-Induced Progressive Collapsed Performance of Cup-Type Transmission Tower-Line System
Applied Mechanics and Materials, 2013The Cup-type transmission tower-line system was a classic representative of high voltage electric power carrier, which was an important lifeline project. However, it frequently collapsed under different environmental loadings, especially strong wind. In this work, four tower five line finite element models simulated wind-induced progressive collapse ...

Analysis on Wind-Induced Vibration Dynamic Responses of Transmission Tower-Line System
Applied Mechanics and Materials, 2013Tower-line system of overhead transmission line are sensitive to wind. Therefore, dynamic effect of wind load should be taken into consideration, for instance, wind-induced vibration coefficient. There might be some errors in the calculation of the coefficient in accordance with ‘Load code for the design of building structures’, for its ignoring the ...
