The 69kV polymer post insulator mainly applies to transformer substation and other apparatus.
69kV polymer post insulator has lots of voltage, the voltage of polymer post insulator can up to 220kV, to suit different requirements. Now most of the small apparatus has chosen polymer post insulator to instead of porcelain ceramic ones since they have more advantage.
69kV polymer post insulator are composed by three main material reinforced fiberglass, composite polymer shed and fittings.
