摘要:
与目前普及应用的棒型碳纤维复合芯导线相比，绞合型碳纤维复合芯导线具有柔软性能良好、安全稳定性高、连接金具简单和架线施工方便的系列优点，是未来碳纤维复合芯导线的发展趋势。为研究该导线在500 kV新建架空输电线路工程中的应用前景，以两典型500 kV双回交流线路模型为例，分别从节材和节能的角度相应选取碳纤维复合芯导线，与推荐的铝包钢芯铝绞线方案进行综合技术经济比较，总结绞合型碳纤维复合芯导线经济性方面的优劣势，以指导实际工程应用。 Abstract:Compared to the widely used ACCC (Aluminum Conductor Composite Core) calbe, the ACMCC (Aluminium Conductor Multi-Strand Carbon-Fiber Core) cable use the multi-strand carbon-fiber core instead of the single carbon-fiber coer in ACCC, which has much better performance: higher stability and improved safety margin, better flexibility, simpler fittings as ACSR and easier for installation. Thus, ACMCC is future development trend of ACCC. In order to study the application prospect of ACMCC in new 500 kV overhead power transmission lines, taking two typical 500 kV double circuti AC lines as examples, different sizes of ACMCC cable are selected according to material-saving and energy-saving principle, and detailed technical and economic comparison is showed compared to the recommended cable, so economic performance of the ACMCC is given to direct the engineering application.
