新建线路圆线与型线结构导线的技术经济比较

Technology and economy comparison of the circular curve and profile conductor in new- build line

型线结构导线是近年新开发的一种新型导线，本文结合具体工程，在机电气性能、经济性、配套金具及施工等方面对圆线与型线进行了比较，通过技术经济比较，表明型线具有线径小、荷载轻、弧垂小、电晕小及年费用低等特点，提出推荐型线导线的技术方案，可供类似工程在导线选择时参考。

Based on practical project, the paper compares the circular curve and profile conductor in the electromechanical properties, economy, matching tools and construction. Through technology and economic analysis, the paper presents that the profile has the char- acteristic of small lead wire diameter, light load, good droop, small corona and low annual cost and recommends the profile techonology plan, which provides a reference to the resemble projects.
