Abstract: In this paper, FRP/Composites application to pole&tower of transmission line and its technical advantages are described. The current R&D of composite pole&tower in domestic and foreign companies and research institutes are presented. The domestic composite poles&towers are under development and pilot production phase, and some of its products have been used in transmission lines on trial. The domestic composite pole&tower products mainly employ the polyurethane and epoxy as their resin matrix and E-glass fiber as their reinforcement, with filament winding process for their production. Performance tests for composite pole&tower include basic material properties, electrical properties, aging performance tests and prototype model test.

Key words: transmission line, composite pole&, tower, technical advantage, application status, performance requirement
