Causes of Hanging Point Fixtures and Insulators Damage of Towers with Heavy Ice Covering and Countermeasures
Ultra-high voltage(UHV)transmission lines play a crucial role in China's electric energy strategy.There are many cases of power system paralysis caused by damage to hanging point fixtures,insulators,and other electrical equipment in transmission lines.Based on the example of the Xindong DC project,this paper explores the damage caused by hanging point fixtures and insulators from the aspects of line icing,conductor galloping,and ice-shedding jump.Moreover,corresponding countermeasures and suggestions are given for different damage types.
