Application:the epoxy fiberglass tension stick rods, organic composite insulators, tension and winding composite stick specially used for tower cross arm which has the higher flexural strength than the tension stick and 4 cm long winding insulator used for high voltage wirings.
What are the advantages of epoxy resin systems used for manufacturing FRP rods in comparison to polyester resin systems?
Epoxy resins are impregnating compounds with the highest available quality of all comparable polymers for the pultrusion of FRP rod materials. Hot curing epoxy resin in combination with anhydride hardener gives an aging/hydrolysis resistant high strength matrix component. Polyester resins are not hydrolysis resistant and have lower mechanical and electrical properties
