本文通过对遂渝铁路的项目背景、设计条件的介绍，对电气化区段线路上采用的不同的接触网悬挂方式、 不同的接触网零件以及不同悬挂方式情况下的安装图示，进行了分析、计算和试验对比，肯定了接触网设计要 综合德国、日本、中国的标准，并在设计中灵活运用的方法，提出了今后在进行高速铁路建设中电气化设计应该 注意的问题，为我国在发展山区高速电气化铁路且装载双层集装箱货物列车的设计积累了经验并通过遂渝线 的试验结果说明了立足自我，学习、引进国外先进技术、设备和材料的路子是正确的。

By introducing background, design condition of ShuiYu railway project, this paper analyzed, calculated and test compared different catenary suspension mode and accessory on the electrification lines. To fix diagram of different suspension mode, catenary design has been praised in synthesizing standards of Germany, Japan and China, using flexible design method, and giving some suggestions to power supply design in high speed railway 、 constructions in future. The experiences of running double-deck container wagon on the high speed railway in mountain area have also been obtained. Through the testing in ShuiYu railway project, we believe it is right to absorb advanced technology and equipment, material from foreign countries.
