在列车运行速度超过160km／h的情况下,保证高质量的集电变得特别迫切的。此外,对接触导线从一个悬挂高度过度到另一个高度时平直度和倾斜度的误差要求更严了。1998年底,在圣彼得堡——莫斯科铁路干线上(里亚波沃——柳班区段的第二和第四工区)进行KC-200型接触网建设的第一阶段,电气化和供电部门的专家首先碰到了要保证接触导线平直度的问题。在这一阶段,横截面 In the case of trains operating at speeds exceeding 160 km / h, it is particularly urgent to ensure high-quality current collection. In addition, the contact wire from one suspension to another over the height of the straightness and tilt error of the more stringent requirements. At the end of 1998, during the first phase of the construction of the KC-200 CET on the St. Petersburg-Moscow Railway (sections II and IV of the Riobov-Libyan section), experts from the electrification and supply sectors first Encountered to ensure contact with the straightness of the wire problem. At this stage, the cross section
