Bare Copper Wire 8mm Stranded is a high-conductivity electrical conductor made of multiple uninsulated strands of pure copper twisted together. With a nominal diameter of 8mm (roughly corresponding to 2 AWG or a cross-sectional area of approximately 50 mm), this heavy-duty wire provides excellent electrical and thermal conductivity combined with the flexibility required for demanding grounding, bonding, and power distribution applications.
Key Specifications & Features
Material: 99.9% pure electrolytic tough pitch (ETP) or oxygen-free copper, left bare without any tinning, insulation, or jacket.
Stranded Construction: Composed of multiple smaller-gauge copper wires twisted in a concentric layout. This design offers superior flexibility, easier routing, and greater resistance to mechanical fatigue and vibration compared to a single solid conductor of the same thickness.
High Conductivity: Delivers maximum current-carrying capacity with minimal electrical resistance and voltage drop.
Corrosion Resistance: Features high natural resistance to atmospheric corrosion, making it highly durable for long-term outdoor exposure or burial.
Primary Applications
Grounding and Bonding: Extensively used as a main grounding electrode conductor (GEC) for residential, commercial, and industrial electrical systems, connecting the main service panel to grounding rods.
Lightning Protection: Serves as a reliable, heavy-gauge path to safely direct high-current lightning strikes down to the earth, protecting structures and equipment.
Substations and Power Grids: Utilized in overhead electrical transmission lines, grounding grids, and heavy-duty machinery grounding.
Cathodic Protection: Employed in specialized systems to prevent the corrosion of buried pipelines, tanks, and structural steelworks.
