Conductor selection is an important assignment for the reconstruction of the transmission line capacity increasing, which di-rectly affects implement scheme and indexes of the project. Based on the typical 220 kV transmission line in Guangdong province, six different conventional and new type of conductor is selected as comparison scheme for reconstruction. Then, a detailed technical econ-omy research including current capacity, mechanical load, sag character, line losses, one-time investment, equivalent annual value and fluctuation of market price is carried out in this paper. Finally, the optimum scheme and suggestions is proposed. The conclusion and method is valuable to actual project.
