Application Analysis of Expanded Conductor in 1000kV UHV Double-Circuit Line

Abstract:

This paper discusses the feasibility and effectiveness of the application of expanded conduct in 1000kVultra high voltage AC (UHVAC) transmission line. Through the comparison and analysis between expanded conduct and conventional conduct in transmission capacity, mechanical properties, project investment, annual cost and other aspects, it shows that the initial investment of expanded conduct is 4% lower than that of conventional conduct; and the annual cost of expended conductor is superior to that of conventional conduct when transmission capacity, power price and use hours are low.
