Electrical ceramics: The electrician's line is a kind of inorganic insulating material. Its advantages as a pillar insulator material mainly include good aging resistance, strong environmental applicability, strong resistance to acid and alkali corrosion, and excellent electrical and mechanical strength. . For the past 100 years, it has been one of the main manufacturing materials for pillar insulators . However, due to higher manufacturing and transportation costs and greater pollution during production, few new materials have been used as pillar insulator materials since the emergence of new materials in recent years.
Tempered glass: Tempered glass is also a kind of inorganic insulating material. Its performance is similar to that of electrical ceramics. It has outstanding aging and corrosion resistance and high production efficiency. At present, it has replaced electrical ceramics as one of the main manufacturing materials of pillar insulators in many places. Synthetic silicone rubber: The obvious advantages of synthetic silicone rubber are its high strength and light weight. After a certain modification, the anti-corrosion performance will also be greatly enhanced, and the cost performance is very high. However, compared to the former two materials, the development started slowly and the scope of application has not been fully developed.
