Insulating FRP rods (also known as core rods for composite insulators) are made from epoxy resin reinforced with ECR-glass fibers using the pultrusion process. These rods serve as the mechanical and insulating core of composite insulators in high-voltage power systems. They feature high tensile strength, superior dielectric properties, excellent weather and chemical resistance, making them essential components in modern electrical insulation applications.
