Suspension composite insulator core rods are essential load-bearing insulation components in high-voltage power systems. Our factory specializes in manufacturing FRP rods made from high-strength ECR (Electrical Corrosion Resistant) glass fiber and epoxy resin, ensuring superior mechanical and electrical properties. These rods are widely used in suspension-type composite insulators for both transmission and distribution applications. We provide full customization for diameter, length, and resin ratio to meet diverse technical requirements.
