摘要
综述了高速电气化铁路接触导线的研究进展及应用现状,指出Cu-Sn、Cu-Cr-Zr及Cu-Mg等合金因具有抗拉强度高、导电率高和耐磨等综合特性,是较理想的接触导线材料。
The research progress and application status of high-speed electric railway contact wire were reviewed.Some newly developed contact wires were introduced,such as Cu-Sn,Cu-Zr-Cr and Cu-Mg alloy wire.Copper alloy contact wire can be widely used in the future,due to its high-tension,high-conductivity and wear-resistance.
