Design and Research on Composite Flanges Applied to Composite Cross Arms

In order to reduce the cross arm length, tower weight and the power line corridor width, it is proposed to replace the conventional steel node with the composite flange, so as to realize the composite connection of composite cross arms. The load behaviors of composite flange are studied by tests and finite element simulations, and results show that the bearing capacity of the composite flange can meet the requirements of general 750 kV transmission lines.
