Product Description Product Description The FRP Core Rod (Fiber Reinforced Polymer Core Rod) is a high-performance electrical insulation material made through pultrusion of epoxy resin and high-strength ECR glass fiber. It is widely used in surge arresters and composite insulators as a support and insulation element that ensures safety and mechanical stability.Product StructureThis rod consists of continuous unidirectional glass fibers embedded in a thermosetting epoxy resin matrix. It is manufactured via pultrusion and heat curing, resulting in a compact, void-free, and smooth surface rod that can be customized with sanding or coating upon request.
