摘要
对Π型刚性接触网和钢铝复合轨两种不同类型的牵引网进行了技术参数的比较。结合广州地铁4号线的线路特点,并从机械耐磨性能和使用寿命比较,从土建投资、供电安全性、对城市影响等方面分析,认为广州地铁4号线采用钢铝复合接触轨具有比较明显优势。
By introducing two main types of electric traction contact system: the overhead catenary system and the third-rail system, along with the different parameters and characteristics this paper makes an analysis of the economic and technical factors of Guangzhou Metro Line 4, and argues that the DC 1500V Steel - aluminum Conduct Rail System is still a better choice.
