Galvanized iron wire is extensively used to support electrical lines, both overhead and underground. In overhead installations, the wire is employed to create sturdy support structures, such as utility poles and transmission towers, which hold power lines aloft. The wire's high tensile strength ensures that it can withstand the weight of heavy cables and withstands the forces exerted by wind, ice, and other environmental factors. Additionally, the corrosion-resistant zinc coating protects the wire from degradation, ensuring long-term reliability and safety for electrical distribution networks.
