70 Sq.Mm Bare Copper Conductor for Overhead Power Lines - 10.65mm Diameter with 0.2646 Ω/km Resistance
70 sq.mm bare copper conductor designed for overhead power transmission and distribution lines. Available in both solid and stranded configurations to meet various electrical construction requirements.
Solid and stranded bare copper conductors are engineered for overhead transmission and distribution applications. Stranded conductors with enhanced flexibility are ideal for uninsulated hook-up connections, jumpers, and grounding systems in electrical construction projects.
Bare stranded soft-drawn copper conductor features concentric-lay-stranded construction using hard-drawn copper wires, available in both single-layer and multi-layer configurations for optimal performance.
