Research Progress of Self-Cleaning, Anti-Icing, and Aging Test Technology of Composite Insulators

Composite insulators are widely used in power systems because of their advantages of light weight, good pollution resistance, and high mechanical strength. With the increasingly serious environmental pollution problem, especially in winter at high latitudes, composite insulators are easily affected by fog, bird droppings, algae, and icing. Long-term exposure to the outdoor insulator surface will cause aging, which will then pose ae potential safety hazard to the stable operation of insulators. Therefore, the self-cleaning, anti-icing, and aging test technologies of composite insulators are particularly important. This paper introduces the research progress and current situation of self-cleaning, anti-icing surface preparation, and aging test technology of composite insulators, and looks forward to the future development of composite insulators.

Automated summary

Composite insulators are widely used in power systems due to their lightweight, pollution resistance, and high mechanical strength. However, they are susceptible to fog, bird droppings, algae, and icing, especially in areas with severe environmental pollution. The long-term exposure of outdoor insulator surfaces can lead to aging, which poses a potential safety hazard to their stable operation. Therefore, the development of self-cleaning, anti-icing, and aging test technologies for composite insulators is of great importance.
