摘要:

大跨越工程导线方案选择的合理性是大跨越工程设计的关键环节。拟建中某1 000  kV特高压交流输电线路工程的大跨越部分,从导线材料、载流量、电气性能、机械特性及经济性等多方面对各比选导线进行详细的技术经济比较和论证,优选出6×JLHA1/EST-640/170型特强钢芯高强铝合金绞线作为推荐方案,该导线在国内外同类特高压大跨越工程中系第1次采用,国内导线生产厂家已完全具备该型式导线的生产能力。

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
