防腐钢包铜钢轨引接线的结构设计和工艺控制

Structure Design and Process Control of Anticorrosion Steel-Clad-Copper Rail Contact Wire

高铁用防腐钢包铜钢轨引接线由引接线和接线端子组成。防腐钢包铜钢轨引接线(不含接线端子部分)主要由钢包铜绞合导体、防腐油脂、耐高温绝缘、耐低温耐油护套组成。通过对防腐钢包铜钢轨引接线结构及性能分析,提出了相关防腐结构设计及生产工艺控制要点,最终满足了其对防腐的较高要求。

For anticorrosion steel-clad-copper rail contact wire of high-speed railway,it is composed of contact wire and connect terminals.Generally,the cable is formed by steel-clad-copper strand conductor,anticorrosive grease filling,high temperature resistant insulation,low temperature and oil resistant jacket.Based on the analysis of the structure and performance of the anticorrosion rail contact wire,some special requirements for the anticorrosion structure design and process control points are proposed,and finally the higher anticorrosion requirements are met.
