In the present work, a method for continuously coating copper on steel wire is heing developed. The pre-treated steels have made to run horizontally through various cells containing cleaning solution, pickling solution, strike bath and plating hath. After a thin coat of nickel, the steel wil-e was plated using an acid copper bath. A single strand horizontal wire plating unit was fabricated for the purpose. Hull Cell was used to optimise the operating conditions of the selected bath. The current efliciency of the process and the electrical resistivity of the coated wires were also measured. The copper coated steel wires may substitute copper cables in tele-communication and other applications.
