Insulators play a vital role in power systems, and there are significant differences in anti-aging performance between insulators made of different materials.Porcelain insulators are one of the traditional insulator materials. They have high mechanical strength and good insulation performance. In terms of anti-aging, porcelain insulators are relatively stable. However, in the long-term use of porcelain insulators, they may be eroded by environmental factors such as acid rain and dirt, and cracks or damage may appear on the surface, thus affecting their insulation performance and service life. In addition, porcelain insulators are heavier and relatively difficult to install and maintain.Glass insulators have good transparency and mechanical strength. In terms of anti-aging performance, glass insulators have strong resistance to ultraviolet rays and are not prone to aging due to long-term exposure to sunlight. At the same time, the surface of glass insulators is relatively smooth and not prone to dirt accumulation, reducing the aging problem caused by dirt. However, glass insulators are easy to break when impacted by external forces, and attention needs to be paid during installation and use.Composite insulators are a type of insulator material that has developed rapidly in recent years. It is made of polymer materials such as silicone rubber, and has the advantages of light weight, high strength, and resistance to pollution flashover. In terms of anti-aging performance, the composite insulator performs well. Silicone rubber materials have good weather resistance and can resist the erosion of environmental factors such as ultraviolet rays, ozone, acid and alkali. Moreover, the surface of the composite insulator is hydrophobic and not easy to accumulate dirt, which greatly reduces the risk of aging caused by dirt. However, during the long-term operation of the composite insulator, problems such as aging of silicone rubber materials and interface discharge may occur, and monitoring and maintenance need to be strengthened.In summary, insulators of different materials have their own advantages and disadvantages in anti-aging performance. When selecting an insulator, various factors should be considered comprehensively according to the actual use environment and requirements, and the appropriate insulator material should be selected to ensure the safe and stable operation of the power system.
