The ECR Glass Fiber Epoxy FRP Rod is a high-strength insulating component specifically engineered as the core structure for electrical composite insulators. Manufactured via pultrusion technology, it uses ECR (Electrical Corrosion Resistant) glass fiber reinforced with epoxy resin, offering superior insulation and mechanical stability in demanding power system environments.
As the load-bearing and insulating core of composite insulators, the FRP rod made with ECR glass fibers provides excellent corrosion resistance and dielectric properties. Its compact composite structure ensures stable long-term performance under UV, humidity, and temperature fluctuations.

Superior Insulation: High dielectric strength and stable under high voltage applications
Excellent Corrosion Resistance: Suitable for acid, alkali, UV, and salt fog environments
Lightweight but Strong: 70% lighter than metals with high tensile/flexural strength
Dimensional Stability: Low thermal expansion and moisture absorption
Highly Machinable: Can be drilled, cut, and coated as per needs
All FRP rods undergo:
Mechanical Strength Testing (tensile, flexural, impact)
Dielectric and Insulation Testing
