electrified railway
1.The DWY telecontrol systems for electrified railway have been widely used along many electrified railway lines.
2.Harbin-Dalian Electrified Railway The 946.5-kilometer Harbin-Dalian Electrified Railway transcends any other of the kind in China in terms of total investment and technological input.
3.CALCULATION OF LONGITUDINAL VOLTAGE PRODUCED IN TELECOMMUNICATION CABLE CORES BY INDUCTION FROM ELECTRIFIED RAILWAY
5.It is shown that an electrified railway tunnel is an effective channel for transmission of language and slow digital signals.
6.Taking the foundation underpinning construction of GuangShen high speed electrified railway bridge for example, this paper introduces the foundation underpinning construction technology.
7.Taking a practical electrified railway tunnel as an example, impedances calculated from different formulas are compared and the relative errors of Carson’s formulas are presented.
8.For the fast- development of electrified railway, based on the experience of the Electric Management Information System (EMIS) of railway traction power supply developed and applied by Zhengzhou railway bureau, the article put forawrd feasible proposals about the design aim, principle , the sub - system and its function, the database design, code design, network structure, equipment, system software and development tools.
9.In this paper the domestic electricity quality indexes and foreign electricity quality indexes are analyzed and compared, and the indexes, which adapt for the electrified railway, are put forward.
10.It is advised to develop domestic copper alloy contact wire as soon as possible to accelerate the localization processs of contact wire used in the high-speed electrified railway on the base of analysing the domestic and overseas research and product of contact wires.
