本文在结合我们所作的阶段性试验结果和收集到的大量国内外试验研究以及使用情况方面的文献资料基础上,指出惯用材料存在的问题,从理论和实践上分析了铝合金整体接触线的优越性和可行性,详细讨论了合金化方案及各种主要性能的设计和施工,论述了选用铝合金接触线具有巨大的潜在经济效益,必将逐步取代铜接触线.
Based on the literature and data collected from a large number of domestic and foreign experimental research and use cases, this article points out the problems existing in conventional materials, and analyzes the superiority of the overall contact line of aluminum alloy theoretically and practically The feasibility and feasibility of this alloy are discussed in detail. The design and construction of alloying schemes and various main properties are discussed in detail. It is discussed that the selection of aluminum alloy contact wires has huge potential economic benefits and the copper contact lines will be gradually replaced.
