Technical Field

Copper alloys are the most widely used material for high speed railway contact wires. However, there has long been a contradiction between high strength and high conductivity in the study and preparation of copper alloy contact wires.

If a contact line with the section of 120mm 2 is adopted, the paving length of electrolytic copper per ton can reach 125% of the original paving length, but the problems of high strength and conductivity of the contact line are required to be solved.
The embodiment of the invention provides a fiber reinforced copper-based composite contact wire, and the specific structure of the contact wire is shown in figure 1.
