Composite High Voltage Epoxy Resin Insulator

Composite high voltage standoff insulators is also called synthetic high voltage epoxy. Its main structure consists of three parts: shed sheath, epoxy glass fiber (FRP) core rod and end fittings. Among them, the epoxy resin insulator shed sheath is made of high-temperature vulcanized silicone rubber, the FRP core rod is a glass fiber reinforced composite material with epoxy resin as the matrix, and the end fitting is a carbon cast steel or carbon structural steel with a hot-dip galvanized layer on the outer surface. 
This structure of composite high voltage epoxy resin separates mechanical strength from external insulation performance. The core rod and shed sheath bear mechanical and electrical loads respectively, thus combining the advantages of the shed sheath material's excellent atmospheric resistance and aging performance and the core rod material's good tensile mechanical properties. As part of the high voltage standoff structure, the hardware mainly plays the role of transmitting mechanical stress and connecting and fixing.
