代替铜导线的钢铝接触导线是我国电气化铁路接触网的主要部件。导线用钢目前大量使用的是10Cu 钢,由于10Cu 钢耐大气腐蚀性能较差,致使磨损量大,导线使用寿命降低。在调整了10PCuRe 钢成份的基础上,研制出低锰含量的耐大气腐蚀钢10PCuRe(D)。在新沪钢铁厂、上海电缆厂、铁道部机车车辆研究所、西安铁路局参加下,用该钢种制成的钢铝导线,
Steel and aluminum instead of the copper wire contact wire is the main component of China’s electrified railway catenary. Wire steel currently used in large quantities is 10Cu steel, 10Cu steel due to poor resistance to atmospheric corrosion, resulting in a large amount of wear and tear, wire life reduced. On the basis of adjusting the composition of 10PCuRe steel, 10PCuRe (D) is developed for atmospheric corrosion resistant steel with low manganese content. In the new Shanghai Iron and Steel Factory, Shanghai Cable Factory, Ministry of Railways Locomotive Research Institute, Xi’an Railway Bureau to participate, with the steel made of aluminum wire,
