Silicone rubber pin insulator gradually replaces porcelain and glass insulator, which become the best insulator in this century. Silicone rubber pin insulator can be used for distribution lines.

Silicone rubber pin insulator is also called composite pin insulator and composite designs generally employ a fiberglass rod for mechanical strength, with an outer housing made from either silicone rubber, EPDM, FRP or EPR.

Compared to traditional insulator, the advantages of Silicone rubber pin insulator have
◆ Lighter weight
◆ Big creepage distance
◆ Excellent mechanical strength
◆ More flexibility in design
◆ Lower Installation cost
◆ Greater durability

According to pin insulator hardware, Silicone rubber pin insulator can be divided into
◆ Tie top pin insulator
◆ Clamp top pin insulator

For example, Silicone rubber pin insulator has lighter weight and lower cost than porcelain pin insulator used for high voltage distribution lines.
