The Fatigue Damage Effect Of Conductor Galloping On The Electromechanical Properties Of Epoxy Resin Insulators

During long-term operation, the vibration of the conductors causes high voltage standoff insulators to be subjected to repeated mechanical stresses, which may lead to material fatigue. Over time, under continuous mechanical impacts, the electromechanical properties of high voltage epoxy may gradually decline, resulting in microcracks or even fracture. Test results show that when epoxy resin insulator experiences prolonged dynamic loads, its internal structure may undergo subtle changes, reducing its ability to withstand external forces.
