自上海地铁一号线接触网系统引进德国弹性底座技术并成功运行后,以弹性支座为支持结构的简单悬挂接触网系统在上海地铁得到了广泛应用。随着弹性支座国产化的实现,上海地铁二号线及其西延伸、地铁一号线上海南站改建工程、上海地铁四号线、上海地铁一号线北延伸、三号线北延伸工程等隧道内接触网均采用了弹性支座简单悬挂形式。由于弹性支座具有对净空要求小及改善简单悬挂触网弹性的特点,在未来的城市轨道交通及电气化铁路中必将有更加广阔的应
Since the introduction of German flexible base technology and its successful operation, the simple suspended catenary system with elastic bearings as its supporting structure has been widely used in Shanghai Subway since Shanghai Metro Line 1 Catenary System. With the localization of flexible bearings, Shanghai Metro Line 2 and its extension of the West, Shanghai South Railway Station Line 1 reconstruction project, Shanghai Metro Line 4, Shanghai Metro Line North Extension, Line 3 North Extension Project Such as the tunnel contact network are used in the simple form of suspension suspension. Due to the requirement of clearance for the elastic bearings and the improvement of the elasticity of the simple suspension cables, the elastic bearings will have a much broader application in the future urban rail transit and electrified railways
