The invention discloses a copper-silver alloy stranded wire for a railway. The copper-silver alloy stranded wire meets the requirements of train acceleration, long-distance climbing and train power supply under special working conditions of mountainous road sections. The cable comprises a central unit which is composed of a single copper-silver alloy filament or a copper-silver alloy stranded unit; the peripheral stranded layer comprises at least one stranded layer, and each unit in the adhesive layer is a single copper-silver alloy monofilament or a copper-silver alloy stranded unit; when the central unit is a single copper-silver alloy monofilament, each unit of the peripheral twisted layer is an equal-diameter copper-silver alloy monofilament; when the center is the copper-silver alloy stranded unit, each unit of the peripheral adhesive layer is the same copper-silver alloy stranded unit, and each group of copper-silver alloy stranded unit is formed by stranding a center copper-silver alloy single wire and a layer of peripheral copper-silver alloy single wire stranded units; and when the central unit is a central stranded unit formed by stranding a plurality of groups of copper-silver alloy stranded units, each unit of the peripheral stranded layer is the same copper-silver alloy stranded unit.

    本发明公开了一种铁路用铜银合金绞线,其满足列车提速、长距离爬坡及山区路段特殊工况下为列车供电的需求。其包括:中心单元,其由单根铜银合金单丝或铜银合金绞合单元构成;外围绞层,其包括至少一层绞层,所述胶层内的每个单元为单根铜银合金单丝或铜银合金绞合单元;当中心单元为单根铜银合金单丝时,所述外围绞层的每个单元均为等径的铜银合金单丝;当中心为铜银合金绞合单元时,所述外围胶层的每个单元均为相同的铜银合金绞合单元,每组铜银合金绞合单元由中心铜银合金单丝和外周的一层若干根铜银合金单丝绞合单元绞合形成;当中心单元为若干组铜银合金绞合单元绞合形成中心绞合单元时,所述外围绞层的每个单元均为相同的铜银合金绞合单元。
