20231期节能导线分析徐炳亮(福建亿兴电力设计院有限公司,福建泉州362000)摘要:从电能损耗和载流量、弧垂、杆塔荷载和年费用等方面,对比铝包钢芯铝绞线、钢芯(高导电率)铝绞线、铝合金芯(高导电率)铝绞线和中强度全铝合金绞线共4种结构5种导线,发现节能导线因自重轻、拉断力小,按国网通用设计原则量身定做的杆塔质量比铝包钢芯铝绞线、钢芯(高导电率)铝绞线轻,基础因荷载小费用也略低,同时电能损耗小于普通导线。关键词:铝绞线;电气性能;机械特性;造价;节能中图分类号:TM247DOI:10.19768/j.cnki.dgjs.2023.01.020AnalysisofEnergySavingTraverseXUBingliang(FujianYixingElectricPowerDesignInstituteCo.,Ltd.,Quanzhou362000,China)Abstract:Fromtheaspectsofelectricenergylossandcarryingcapacity,sag,towerloadandannualcost,thecomparisonismadeamongaluminumcladsteelcoredaluminumstrand,steelcored(highconductivity)aluminumstrand,aluminumalloycored(highconductivity)aluminumstrandandmediumstrengthallaluminumalloystrand.Itisfoundthattheener-gy-savingconductorhaslowbreakingforceduetoitslightself-weight.AccordingtothegeneraldesignprinciplesoftheStateGrid,theweightofthepoletowertailoredislighterthanthatofaluminum-cladsteelcorealuminumstrandedwireandsteelcore(highconductivity)aluminumstrandedwire,andthefoundationisslightlylowerduetothesmallload,and...
