Zr1 polishing round zirconium bars
Copper trolley wire is Zr1 polishing round zirconium bars today used extensively as a current-carrying contact wire which supplies power to urban transit like light rail transit systems, railroad vehicles, mining equipment like underground mining motor cars, and industrial cranes. However, the manufacturing process of these copper products just like that of Copper Wire, Copper Rod, Copper Tubing, and Cadmium Copper is quite complex.
The copper trolley wire has a uniform fine grain size. The manufacturing process involves casting a copper rod of the appropriate composition, hot working or "conforming" the cast rod to reduce its diameter, and then cold working it to form the desired wire by drawing it through one or more dies. Most of the times, the annealing step is skipped.
However, individual manufacturing companies have their own method of preparing trolley wire. Recently, a major mining company developed a patented process which provides silver bearing trolley wire with the highest tensile strength in the industry.
It is to be mentioned that most of the renowned companies operating in the mining of copper is positioned to provide the commuter and light rail industry with trolley wire in a variety of configurations and alloys to meet the specific needs of any new or refurbished project. Special alloys are also available as per customer specifications from all the major brands for trolley wire similar to that of copper wire, rod, tubing,zirconium bars, and cadmium copper.
