碳纤维复合芯导线因材料和结构与一般钢芯铝绞线不同，其应力、弧垂特性、输送容量、电能损耗等具有明显的优越性。从不同设计条件下的10 000多个导线应力弧垂计算数据中摘录了一些有代表性的数据，分析了该导线在输电线路新建、增容改造工程中的应用，阐明了该导线的实用性和经济性。

The material and structure of aluminum conductor with carbon fiber composite core(ACCC) are different from those of common aluminum cable steel reinforced(ACSR). ACCC has obvious advantages in stress, sag characters, transmission capacity, and energy loss etc. Some typical data are extracted from more than 10,000 data for sag calculation of conductor stress under various design conditions, for analyzing the application of ACCC in new transmission lines and capacity expansion transformation. As a result, the applicability and economy of ACCC is illustrated.
