The ECR fiberglass rod (diameter range 4.15mm to 220mm) is the core component of polymer insulators, made of epoxy resin and alkali-resistant ECR-glass fiber through pultrusion. This type of FRP (Fiber Reinforced Plastic) rod offers outstanding mechanical strength, excellent electrical insulation, and superior corrosion resistance. It is widely used in high-voltage transmission and distribution systems.
