Epoxy Pultruded Fiberglass Rod, also known as an FRP rod, is a high-performance insulating structural material manufactured using epoxy resin as the matrix and glass fiber as the reinforcing material through a continuous pultrusion process. This advanced production method enables the rods to be produced in extended lengths and customized according to specific user requirements.
With excellent electrical insulation properties, high mechanical strength, and outstanding dimensional stability, epoxy pultruded fiberglass rods are widely used in medium- and high-voltage electrical equipment, power transmission and distribution systems, renewable energy applications, and various industrial insulation fields.
