Abrégé

The present invention concerns a hanger wire (drop wire) for contact wires of railway electrical lines, which comprises first wires made from copper or an alloy thereof combined with second wires consisting of a steel core coupled with a layer made from copper or an alloy thereof. Such a hanger wire is particularly suitable for high speed railway lines, since it has high mechanical performance, in particular in terms of tensile and compressive strength and fatigue strength, and at the same time it has high electrical conductivity, without increasing the weight.
