  Why Clean High Voltage Insulators of Live Transmission Lines with Drones?

  Since power insulators are exposed to outdoor environments for extended periods, their surfaces gradually accumulate dust and dirt. In humid conditions, such as foggy or light rain days, these pollutants can form conductive paths, reducing the insulator’s resistance. When large amounts of dust absorb moisture, surface leakage currents increase, which in severe cases may lead to flashovers, causing transmission line trips and affecting the reliability of power supply. Furthermore, contaminants can also corrode the insulators over time. Therefore, regular cleaning is essential to slow down the aging of insulators, extend their service life, and ensure reliable power transmission.
