The Transmission Line Composite Cross-arm Insulator FRP Rod is a fiber-reinforced plastic core rod made from epoxy resin and ECR glass fiber using a pultrusion process. It is the key structural component in composite cross-arm insulators used in high-voltage transmission lines. The FRP rod ensures excellent electrical insulation and mechanical properties, significantly enhancing the reliability and longevity of transmission systems by replacing traditional ceramic or metal supports.
