Compared with other types of insulators, such as ceramic insulators, tempered glass insulators have the following main advantages:

1. High mechanical strength: Tempered glass insulators can withstand greater tension and pressure, which makes them more reliable in applications such as high-voltage power lines.
2. Good pollution resistance: The surface of the glass material is not easy to accumulate pollution, which reduces the flashover accident caused by pollution and improves the safety of the power system.
3. The self-explosion rate is relatively low: When the tempered glass insulator fails during use, it often shows self-explosion. This failure mode is easy to be found and located, which is conducive to timely maintenance and replacement.
4. The production process is relatively simple: The production process of tempered glass insulators is relatively simple, which helps to reduce costs and improve production efficiency.
5. Beautiful appearance: Tempered glass insulators are usually transparent or translucent, and the appearance is beautiful and generous, which to a certain extent enhances the overall image of power facilities.
In order to meet the market request, Jiangxi Huayao electric Co.,ltd has established a production line for ultra-high voltage tempered glass insulators with advanced production technology by introducing world-class production and testing equipment from Germany, Italy, and other countries.
