Large-Crossing Conductor Selection of 1 000 kV  UHVAC Transmission Line

doi:10.3969/j.issn.1000-7229.2015.05.015

Abstract

Abstract:

The reasonability of conductor selection is the key link in large-crossing transmission line design. Depending on the large-crossing section of a 1 000 kV UHVAC transmission line, this paper technically, economically compares and demonstrates the selected conductors from aspects of the material, current-carrying capacity, electrical performance, mechanical characteristics and economy. The 6×JLHA1/EST-640/170 extra-high strength aluminum alloy conductor steel reinforced was recommended, which was first applied in UHV large-crossing project at home and abroad. Domestic manufacturers have been fully equipped with they production capacity of this type conductor.

Key words: large-crossing, UHVAC, conductor selection, extra-high strength aluminum alloy conductor steel reinforced
