Stranded Hard Drawn Copper Conductors for Overhead Lines

Our stranded hard drawn copper conductors are specially designed for overhead power transmission and distribution lines. Manufactured from high-quality, hard drawn copper wire, these conductors feature excellent electrical conductivity, durability, and mechanical strength. The stranded construction provides increased flexibility and ease of installation, making them suitable for long spans and complex routing. Ideal for use in overhead line systems, these conductors are corrosion-resistant and capable of withstanding environmental stresses, ensuring reliable performance and long service life in various climatic conditions.
