Collapse Analysis of a Transmission Tower-Line System Induced by Ice Shedding [PDF]
Frontiers in Physics, 2021 Ice shedding causes transmission lines to vibrate violently, which induces a sharp increase in the longitudinal unbalanced tension of the lines, even resulting in the progressive collapse of transmission towers in serious cases, which is a common ice-based disaster for transmission tower-line systems.
