How Are Epoxy Insulators Installed?

high voltage standoff insulators, its main structure is generally composed of three parts: shed sheath, FRP core rod and end fittings.

Among them, the shed sheath is generally made of organic synthetic materials, such as EPDM rubber, high-temperature vulcanized silicone rubber, etc.;

The FRP core rod is generally a FRP composite material with glass fiber as reinforcement material and epoxy resin as matrix;

The end fittings are generally carbon cast steel or carbon structural steel with hot-dip galvanized layer on the outer surface

So there is no metal rod in the middle, and the FRP core rod and silicone rubber are both insulating parts, thus achieving insulation.
