According to the copper-silver alloy contact wire, the tensile strength of the copper-silver alloy contact wire is improved from common 380 MPa to 440 MPa or above, the electric conductivity can still be kept at 90-98% IACS, the current-carrying capacity is not obviously reduced, and the requirements for train speed increasing and special environments are met. The copper-silver alloy wire is a single copper-silver alloy wire with the cross section area larger than or equal to 120 mm < 2 > and comprises, by weight, 0.06%-5.0% of silver, less than or equal to 0.1% of mixed components and the balance copper and inevitable impurities, the mixed components are composed of 0.02%-0.06% of Ga, 0.01%-0.04% of La and 0.01%-0.02% of Ti, and the total mass of the inevitable impurities is not larger than 0.02%.

    本发明公开了一种铜银合金接触线,其将铜银合金接触线抗拉强度从普通的380MPa提升到440Mpa以上,而导电率仍能保持在90~98%IACS,载流量无明显降低,满足列车提速及特殊环境需求。其为横截面积大于或等于120mm2的单根铜银合金线,其按照百分比的成分含量为,0.06%~5.0%的银、≤0.1%含量的混合成分、其余为铜和不可避免的杂质,其中混合成分由0.02%~0.06%的Ga、0.01%~0.04%La、0.01~0.02%Ti三者组成,不可避免的杂质总质量不大于0.02%。
