The PH type extension ring is a universal connection fitting used to connect insulators. Its structural dimensions are designed to match those of the insulators, such as ball head hanging rings and bowl head hanging plates. It is primarily used to connect the insulator string to hardware, the clamp to the insulator string, and the lightning conductor to the pole.
