Preview:
Product Description FRP rod is widely recognized as the "inner core" of composite insulators, providing both mechanical strength and electrical insulation. Made from fiberglass and epoxy resin, FRP rods are lightweight yet extremely strong, making them the preferred material for high-voltage insulators in power transmission, substations, and railway electrification projects. Technical ParametersParameterValue/RangeDiameter Range6mm - 40mmCustom Length≤ 6000mmTensile Strength≥ 1200 MPaFlexural Strength≥ 900 MPaVolume Resistivity≥ 1.0 × 10^14 Ω·cmDielectric Strength≥ 18 kV/mmWater Absorption≤ 0.05%Working Temp.-40oC ~ +150oCApplications Transmission Lines: As the core material of composite insulators for overhead lines.Distribution Networks: Ensures reliable performance in urban and rural grids.Substations: Used in station post insulators and wall bushings.Railway Electrification: Provides safe insulation for catenary insulators.Customized ProductionLeadFRP offers FRP rods in multiple specifications. OEM/ODM services are available to meet specific requirements of voltage levels, environmental conditions, and mechanical performance. Customers can request tailored designs to fit their insulator production.FAQ Q1: What is the difference between FRP rods and regular fiberglass rods?A1: FRP rods are manufactured under high-pressure pultrusion, ensuring higher tensile strength and dielectric properties for electrical insulator use.Q2: How long is the service life of FRP rods?A2: Under normal conditions, FRP rods can last for more than 30 years without maintenance.Q3: Do you provide customized FRP rods based on drawings?A3: Yes, we can customize dimensions, surface treatment, and packaging according to client requirements.
