Alumina Insulator Uses
Insulators are widely used in various industries, especially in the electrical industry. Because of its superior insulation performance, alumina is a very superior insulating material! Alumina insulators are used in high-voltage transmission lines, substation equipment, cable joints and other applications!
Power industry: Many insulating parts of transformers, switchgear, circuit breakers and other equipment are made of alumina! Its powerful performance makes it more durable than other materials!
Electronic industry: Alumina insulators are very good protectors. Some precision semiconductors, electronic tube devices, integrated circuit substrates, etc. cannot do without its protection. Its superior insulation and high temperature resistance make alumina a very stable protective and heat dissipating material.
In addition, alumina insulators are also widely used in other industries, such as high-temperature components and insulating materials in the aviation industry, and insulating materials in microwave communication equipment. Alumina ceramic insulators can provide stable electrical performance and extremely low loss.
