Pin polymer insulator-power pole insulators​

All fittings undergo a zinc-plating finish and are assembled using an ultrasonic‐monitored, computer‑controlled coaxial pressure‐crimping technique, resulting in a pristine appearance and consistently dependable joint integrity.

We employ ECR mandrels that are specially reinforced for high‑temperature service and feature enhanced acid resistance.

A labyrinth‑style seal at the interface of the fitting and rod provides superior waterproofing.
