日前，由中鐵電氣化局電氣化公司開發的“既有電氣化鐵路250km/h 接觸網系統工程技術研究”科研項目，通過中國中鐵股份公司科技成果鑒定，該成果此前已通過上海市、湖北省的科技成果評審。評審認為，該成果填補了國內外空白，總體技術處于國際先進水平。
接觸網(wang)(wang)上部施(shi)工(gong)(gong)(gong)方法特別(bie)是(shi)接觸網(wang)(wang)懸(xuan)掛(gua)(gua)調整的標準化(hua)(hua)(hua)、數據化(hua)(hua)(hua)、系列(lie)化(hua)(hua)(hua)是(shi)當今(jin)電(dian)氣化(hua)(hua)(hua)工(gong)(gong)(gong)程施(shi)工(gong)(gong)(gong)技術(shu)(shu)發展的方向。既有電(dian)氣化(hua)(hua)(hua)鐵路250km/h接觸網(wang)(wang)系統(tong)成套(tao)工(gong)(gong)(gong)程技術(shu)(shu)研究，依托(tuo)滬寧線既有電(dian)氣化(hua)(hua)(hua)鐵路250km/h提速改造項目，解決了彈鏈(lian)形(xing)接觸網(wang)(wang)接觸懸(xuan)掛(gua)(gua)施(shi)工(gong)(gong)(gong)的關鍵技術(shu)(shu)，為今(jin)后(hou)相關工(gong)(gong)(gong)程的施(shi)工(gong)(gong)(gong)打下了堅實(shi)的技術(shu)(shu)基礎。
