Composite insulators and surge arresters are important components of power systems, and are widely used with the popularization and development of power systems. In recent years, the types and performance of insulators and arresters have been continuously improved, especially the widespread application of composite insulating materials, which has gradually extended from power systems to other fields such as rail transit. At the same time, with the continuous expansion of the global power grid construction scale and the rapid development of high-speed EMUs, electric locomotives and electrified railways in my country, the market demand for insulators and arresters continues to increase, which promotes the development of the industry. In terms of specific products, although the overall output of insulators and arresters has maintained growth, the product structure has changed. With the application of composite materials such as silicone rubber, composite insulators have been rapidly popularized due to their strong hydrophobicity and light weight.
