Development Trends: Insulator Manufacturing and Use Technology

The appearance structure of porcelain and glass insulators has not undergone revolutionary changes in the past 100 years, but the improvement of materials, processes, and structures has not stopped and is in continuous progress, and is highlighted in the following aspects:

1. The strength of electric ceramic insulators produced by the isostatic pressing process is greatly improved, and in the case of manufacturing large-sized pillar insulators and porcelain sleeves, the process has gradually replaced the trend of ordinary wet production processes.

2. With the increase of transmission voltage level, the requirements for the electromechanical destruction load of monolithic insulators are getting higher and higher. At present, electric porcelain insulators with an electromechanical destruction load of 300KN, 400KN, 500KN or even 800KN can be manufactured.

3. Due to improvements in manufacturing processes and materials, the self-detonation rate of glass insulators has dropped significantly, which is of great significance for improving the reliability of glass insulators.

4. The improvement of the insulator design is an eternal task. The shape of the insulator is of regional applicability, and it is impossible to find out that a shape insulator has the best use effect all over the world.
