Summary
The PH type extension ring is a versatile connection fitting used to connect insulators in overhead transmission lines. It is designed to match the structural dimensions of insulators, such as ball head hanging rings and bowl head hanging plates. The main applications of the PH type extension ring include connecting the insulator string to hardware, attaching the clamp to the insulator string, and connecting the lightning conductor to the pole.
