Effect of Power Line Type on The Safety of Transmission Tower

The supply of electricity is directly affected by the structural safety of transmission tower. The unsuitable power line type can impose extra forces on transmission tower. The failure within transmission tower results in power outage because the designed power transmission tower cannot bear the extra force loading. In this paper, the mechanical responses in transmission tower with different power line types were calculated by means of finite element software. Commercial software Abaqus was employed for analyzing the structural safety of transmission tower. Ten kinds of power line were chosen to impose static forces on transmission tower. Based on the finite element results, the maximum stress and displacement were obtained. When the dimension of power line is less than a certain value, the transmission tower is safe; otherwise, the transmission tower may collapse.
