Abstract The tower line system will be in an unsafe status due to uniform or
uneven fall of ice coating which is attached to the surface of tower and lines.
The fall of ice could be caused by wind action or thermal force. In order to
study the dynamic characteristics of the self-failure of the transmission line
under the action of dynamic wind load, a finite element model of the two-span
transmission tower line system was established. The birth and death element
methods are used to simulate the icing and shedding of the line. Tensile failure… More >
