Pre-twisted Wire Corrosion Resistance Enters A New Stage: Exploration And Practice Of Material Innovation

In recent years, more and more engineering and research institutions have paid attention to the durability of armour rod in complex environments. To address the corrosion issues of armour rod in transmission line under humid, chloride-containing, or marine atmospheric conditions, the industry has gradually introduced a variety of new materials and protective technologies to enhance the overall corrosion resistance of armor rods conductor.

Some manufacturers have begun using galvanizing or epoxy coating processes. These coatings provide a protective layer for the steel wire, isolating it from corrosive media such as air, moisture, and chloride ions.

Meanwhile, stainless steel stranded wire has also entered practical applications. Due to its high corrosion resistance imparted by its alloy composition, stainless steel is used in harsh environments such as marine and chemical industries.
