High strength suspension insulator FRP core rods are essential components in composite insulators, especially for high voltage power transmission in harsh environments requiring high corrosion resistance. FRP (Fiber Reinforced Polymer) rods are made from epoxy resin and ECR glass fibers through pultrusion, offering excellent electrical insulation and mechanical strength. This article gives a comprehensive overview of this product category.
The FRP core rod for suspension insulators is made from epoxy resin combined with ECR (Electrical and Chemical Resistant) glass fibers via advanced pultrusion. It serves as the structural backbone of composite insulators, providing high mechanical strength and electrical insulation. The rod performs reliably even in acid rain, coastal, or polluted environments.
