摘要/Abstract

摘要： 针对铜资源日益紧张造成电线电缆行业原材料成本压力的问题，分析铜、铝材料性能差异，完成等传输容量下铜、铝导体截面换算，依据现有生产工艺，采用解析法，完成铜、铝导体海缆参数计算，对比分析铜、铝导体海缆的技术经济性，进一步研究铝导体连接性能。结果表明：等传输容量条件下，铜、铝导体海缆单位质量近似相等，两者损耗及短路电流特性相近，铜导体海缆材料成本为铝导体海缆的110%~180%，采用交流氩弧焊可使铝导体接头具备良好电气与机械性能，铝导体海缆经济性更优。

Abstract: In view of the increasing shortage of copper resources, which causes the high cost of raw materials in wire and cable industry, this paper analyzes the performance differences of copper and aluminum materials, and calculates the cross-section conversion of copper and aluminum conductors under equal transmission capacity. According to the existing production process, adopting the analytical method, this paper completes the parameter calculation of copper and aluminum conductors for submarine cables, and the economic applicability and electrical characteristics of copper and aluminum conductor submarine cables are compared, including the further study on the connection performance of aluminum conductor. The statistics show that the unit mass of copper and aluminum conductor submarine cables is approximately equal under the condition of equal transmission capacity. The loss and short circuit current characteristics of the two conductors are similar. However, the cost of copper conductor submarine cables is 110% ~180% of that of aluminum conductor submarine cables. Good electrical and mechanical properties of aluminum conductor joints can be achieved by AC argon arc welding. Therefore, the economic performance of aluminum conductor submarine cable is comparatively better.

Key words: submarine cable, equal transmission capacity, copper conductor, aluminum conductor, technical and economical performance
