Composite Insulator Market Processing and Customization: After several years of outdoor exposure, composite insulators may experience discoloration, powdery formation, and cracking. This degradation is due to the chemical changes in the surface material of the insulator caused by the degree of discharge, ultraviolet radiation, and contamination deposits. This deterioration also increases the frequency of discharge. In terms of mechanical strength, it is generally believed that the material used for the core rod has a creep tendency, and the mechanical strength of composite insulators under load tends to decrease over time, with the degree of decrease depending on the magnitude and duration of the load. To enhance the lifespan of composite insulators, in addition to design and manufacturing techniques, the selection of materials is crucial. The key to designing composite insulators lies in reducing the frequency of surface discharges caused by contamination.
