摘要
简述了国内外耐热导线在架空输电工程中的应用、技术发展水平和目前国内的需求状况,介绍了耐热导线的种类、结构和性能特点,对比分析了不同耐热导线在金具使用、工程造价和线损等方面的差异,为耐热导线设计选型提供参考。
This paper overviewed the application of the heat-resistant conductor used in overhead transmission lines both at home and abroad, the latest development of the technology, and the present domestic demand for the type of conductors. It also introduced the types, structures and performance characteristics of the conductor, compared and analyzed differences among heat-resistant conductors of different types in terms of the use of fittings, project cost, and the line loss. The paper c.an provide some useful references for the selection and deign of heat-resistant conductors.
