- Product Description
-
Aluminum-clad steel-core aluminum stranded wire is an overhead conductor composed of aluminum-clad steel wires serving as the reinforcing core, combined with hard aluminum strands. Compared to conventional steel-core aluminum stranded wire, this type is 5% lighter in weight, offers a 2–3% increase in current-carrying capacity, reduces sag by 1–2%, and lowers power losses by 4–6%. Additionally, it boasts excellent corrosion resistance, long service life, a simple structure, and ease of installation and maintenance—making it ideal for transmission lines across various voltage levels, especially those requiring a higher aluminum-to-steel cross-sectional ratio. It’s also well-suited for use in coastal areas, saline-alkali regions, and industrial zones classified as Class III or IV, where pollution levels are elevated.
