Product Introduction
Epoxy pultruded fiberglass rods, also known as FRP Rod,, are high-performance insulating structural materials manufactured using epoxy resin as the matrix and glass fiber as reinforcement through a continuous pultrusion process.Therefore, the length can be longer and customized according to user needs
Thanks to their excellent electrical insulation properties, high mechanical strength, and outstanding dimensional stability, epoxy pultruded rods are widely used in medium- and high-voltage electrical equipment, power transmission and distribution systems, renewable energy, and industrial insulation applications.
Industry standard
National standard GB/T19519
Power industry standard DL/T1580-2016 DL/T810 DL/T864
International Electrotechnical Commission Standard IEC61109 IEC61952
American Standard C29.13-2000
Highlight: Performance of our E-glass rods is higher than normal rods by 20%, suitable for application to all kinds of composite insulators manufacture techniques, especially to injection technique.
Main application
1.Mainly apply to as insulating structural parts, screw processing parts and high-voltage disconnector in transformers, motors and electrical equipments.
Insulating support rod in T-GCB, GIS and PASS disconnector equipment and insulating support parts in arc extinguish chamber ;Other insulating parts used in PT, CT, DS, ES and other elements, their most main function is isolation of potential.
2.Composite insulators
For composite suspension & tension insulators (Diameter Ф16—Ф40),
For composite pin insulators((Diameter Ф24—Ф53),
For composite cross arm insulators(Diameter Ф28—Ф80)
For composite post insulator (Diameter Ф28—Ф130)
For composite surge arresters(Diameter Ф5—Ф40),
For composite fuse cutout (Diameter Ф19—Ф36)
