本論文は交流抵抗試験平台を構築し、従来のACSRと3種の省エネ導体の交流抵抗・温度上昇特性を測定した。重慶の主要送電線と連絡線を事例に送電容量・線路損失・CO2削減効果を比較し、JLHA3が損失・炭素削減ポテンシャル最大だが増分投資が大きく経済性が劣ることを示す。JL3/G1Aは増分投資と省エネ効果のバランスが良く高稼働の幹線に適し、低稼働の連絡線ではJL3/G1Aのみが辛うじて経済的と結論づける。
English
This study builds an AC resistance test platform to characterize conventional ACSR and three energy-saving conductors, then compares transmission capacity, line loss and CO2 reduction using Chongqing main and tie-line cases. JLHA3 shows the lowest AC resistance and greatest carbon-reduction potential but its high incremental investment weakens economic competitiveness under the assumed carbon price. JL3/G1A balances investment and savings, being economically favorable for high-utilization main lines, while only JL3/G1A remains marginally viable for low-utilization tie-lines. The work supports hierarchical conductor selection and low-carbon retrofit of transmission lines.

日本のGX文脈において
日本のGX文脈では、送配電網の脱炭素化・損失低減は電力セクターのScope2削減や再エネ大量導入に伴う系統増強投資の経済性評価に直結する。炭素価格を織り込んだ設備投資判断の一事例として、国内電力・インフラ企業の投資回収評価に示唆を与える。
In the global GX context
Grid loss reduction and conductor retrofit sit at the operational core of power-sector decarbonization, informing how utilities weigh capex against carbon savings under an internal or external carbon price. It offers a concrete engineering-economics template relevant to transition-planning and grid-investment disclosure under ISSB/TCFD physical and transition risk framing.

📄 Abstract（原文）
Against the background of the “Dual Carbon” strategy, adopting energy-saving conductors is a vital measure to reduce transmission line losses and carbon emissions. In this paper, an AC resistance test platform is built to characterize the AC resistance and temperature-rise features of conventional ACSR and three energy-saving conductors. Typical main transmission lines and tie-lines in Chongqing are selected as engineering cases to compare their transmission capacity, line loss and CO2 emission reduction performance. The results demonstrate that JLHA3 has the lowest AC resistance and the greatest potential for loss and carbon reduction, yet its high incremental investment weakens its economic competitiveness under the adopted carbon price scenario. JL3/G1A strikes a good balance between incremental investment and energy-saving benefits, making it the economically favorable option for high-utilization main supply lines. For tie-lines with low annual utilization hours, only JL3/G1A remains economically viable among the three energy-saving conductors, although its economic margin is narrow; JLHA3 and JL3/LHA1 fail to recover their additional construction costs over the whole service life cycle. This study can support hierarchical conductor selection and the low-carbon retrofit of transmission lines.
