为了解决海底同轴电缆系统的经济化和对付铜资源的枯渴,用铝代替以往的铜作为海底同轴电缆的外导体,同时也谋求外护套材料的经济化,对铝同轴电缆进行了研究。主要研究的课题是:(1)决定最合适的电缆结构,明确电缆的机械特性、直流特性等基本特性,同时确立标准传输特性。(2)明确有关不加碳黑的外护套材料的耐气候性。同时,根据二次试制电缆的评价,决定了电缆的结构及标准传输特性,拟定了现场试验用的电缆的设计方案,确认通过评价而达到所期望的目的,还对外护套材料的耐气候性进行了研究。本报告就铝电缆的结构,有关特性,重点阐述了现场试验用电缆的评价。
In order to solve the economic submarine coaxial cable systems and copper resources to deal with the thirst quenching aluminum instead of the old copper as the outer coaxial cable submarine conductor, but also to seek the outer jacket material economy, the aluminum coaxial cable Study. The main research topics are: (1) determine the most appropriate cable structure, clear mechanical properties of cables, DC characteristics and other basic characteristics, while establishing the standard transmission characteristics. (2) Clarify the weatherability of the outer jacket material without carbon black. At the same time, according to the evaluation of secondary trial cable, the structure and standard transmission characteristics of the cable are decided, the design scheme of the cable for field test is drawn up, the desired goal is confirmed through the evaluation, and the weather resistance of the outer jacket material Were studied. This report focuses on the structure and characteristics of aluminum cables, highlighting the evaluation of cables for field testing.
