Porcelain pin post insulator is also a type of porcelain insulator, which was produced by wet process. Pin post insulator not only has the puncture proof advantage of line post insulator, but also has the high creepage distance advantave of pin insulator. Pin post insulators also line line post insulators and pin type insulators which mainly used for distribution line up to 33kV. And for pin post insulators, the main market is in Southeast Asia, Mexico.
