摘　　要：低风压导线是一种架空输电线路用的特种导线,随着输电线路建设的快速发展,低风压导线逐渐受到关注。运用流体力学理论对低风压导线的运行机理作了分析。介绍了日本住友电工公司和日本古河电工公司研究开发的低风压导线的结构形式和导线风洞试验结果,分析比较了各自开发的低风压导线和普通导线的特性区别,列举了日本古河电工公司开发的低风压导线的工程应用情况。另外,分析并提出了开发低风压导线的关键问题。The drag reduced conductor is a dedicated conductor for overhead transmission lines and has gradually attracted attentions along with the rapid development of overhead transmission lines.The working mechanism of the drag reduced conductor is analyzed in this paper by using the theory of hydromechanics.The paper introduces the structure and tunnel testing results of the drag reduced conductors developed respectively by two Japanese companies and compares their characteristic differences.Their application cases are also presented.In addition,the paper analysis and put forword the key issues of drag reduced conductor development.
