Cause Analysis and Prevention Measures of Line Galloping in Transmission Line Design

With the rapid development of power construction, the history of overhead transmission lines has been lengthened. With the continuous change of Iranian environment and climate, the installation and operation of transmission lines are facing a variety of challenges. In recent years, various galloping phenomena may occur in the operation and maintenance of transmission lines in Iran. In this process, the operation and maintenance personnel take photos of them and collect various influence data. After analyzing the data from other countries, Iran analyzes the causes of galloping of transmission lines, mainly from the weather factors and icing factors. After comprehensive analysis, the reasons for galloping of overhead transmission lines are obtained, targeted solutions are given, and the galloping problem is also effectively controlled. In the process of handling the galloping line, it is necessary to cut off the power to ensure the safety of the operation and maintenance personnel. This process also optimizes the operation and maintenance of the transmission line to meet the power transmission demand in the later period.
