城市轨道牵引供电电缆选型分析

Analysis on the lectotype of power cables for urban mass transit traction

结合国内城市轨道供电系统的特点,从绝缘、外护套、防护层、阻燃性能等方面分析了 城市轨道直流电力电缆的结构性能要求,得出了适合我国城市轨道的直流电力电缆的基本类型。

With the specific characteristics of the urban mass transit supply system taken into account, the paper analyses the requirement on the structural performances of the DC power cables for the urban mass transit tractions, such as the insulation, outer sheath protection layer and fire resistance. Basic types of the DC power cables suitable for the operations in China are suggested.
