The FRP (Fiberglass Reinforced Plastic) Fiberglass Core Rod is a critical load-bearing and insulating component for electrical, renewable energy, and industrial sectors. As the structural core of composite insulators, it endures tensile, compressive, and bending loads from conductors, wind, and ice in overhead transmission lines. Composed of continuous E-glass fibers (Electrical Grade Glass) embedded in a thermosetting epoxy resin matrix, it is manufactured via pultrusion for uniform fiber alignment. Diameters range from φ16mm to φ80mm, with customizable lengths.
Exceptional Mechanical Strength: Pultrusion ensures unidirectional fiber alignment, delivering tensile strength up to 1200 MPa and a better strength-to-weight ratio than steel, ideal for weight-sensitive load-bearing applications.
Lightweight & Corrosion-Resistant: 70% lighter than metal rods, easing transportation and installation. Epoxy resin and E-glass fibers resist corrosion, rust, and chemicals, suitable for coastal (salt fog) or industrial environments.
Superior Insulation: Volume resistivity over 10¹⁴ Ω·cm prevents current leakage in composite insulators, reducing flashover risks in high-voltage systems.
Weather & UV Resistance: UV-stabilized epoxy resin withstands -50°C to +80°C and long-term outdoor exposure without degradation, extending end-product service life to over 20 years.
Precise Quality: Continuous pultrusion ensures uniform density, smooth surfaces, and ±0.3mm diameter tolerance, meeting strict manufacturing requirements.
Composite Insulator Manufacturing: For 110kV-1000kV composite insulators, φ22mm-φ40mm FRP rods serve as internal load-bearing structures, supporting insulator sheds and withstanding conductor tension across plains, mountains, and coasts.
Wind Turbine Blades: φ30mm-φ50mm rods reinforce wind turbine blades, enhancing stiffness and fatigue resistance while reducing blade weight to improve energy efficiency.
Oil & Gas Pipelines: φ45mm-φ70mm rods act as insulation supports between offshore/onshore pipelines and metal brackets, preventing electrochemical corrosion.
Electrical Cross-Arms: φ16mm-φ28mm rods are used in lightweight composite cross-arms for urban MV grids, reducing pole load and improving corrosion resistance.
Dimensional Customization: We produce rods with diameters from φ16mm to φ80mm and lengths up to 12 meters (or longer) for specific designs.
Testing & Reports: Tensile, bending, and resistivity tests are conducted, with reports complying with IEC 61109 or ISO 1043 standards.
Technical Consultation: Our engineers advise on material compatibility, load calculation, and installation to optimize end-product performance.
Bulk Order Benefits: Flexible production schedules, bulk discounts, and delivery guarantees are offered for large projects (e.g., HV transmission lines, wind farms).
Warranty: A 5-year warranty covers material defects, with free replacements for quality issues.
