Porcelain pin type insulators,composite porcelain pin insulator
With the emergence of electric power, porcelain insulators were manufactured in 1960s. After porcelain insulator can be divided into porcelain pin type insulators, porcelain line post insulator in the light of application.
The utility model relates to the field of electric used in power transmission porcelain insulators, especially composite porcelain pin insulator. With the development of electric fields, power transmission is more important. In the power transmission in order to prevent leakage, it is necessary poles fixed porcelain pin type insulators. Currently, the power lines using porcelain insulators, due to structural reasons exist during operation is easy to produce discharge gap, forming leakage current, high voltage electric field under the action of partial discharge, thereby generating dendritic discharge, anti-fouling weak, prone to flashover, blown tie wire, insulators can cause serious breakdown in the transportation, installation or external damage will produce cracks and breakage, resulting in power line failure.

Sometimes Composite porcelain pin insulator can be called polymeric pin insulator. The name is shorter and using widely in the world.
