Bare Copper Wire for Electrical Purpose

Copper's excellent electrical and thermal conductivity provides the most essential, free-moving electrons which electrical wiring requires. Annealed copper cable must have low resistivity to electrical currents to ensure a power source can push current through. However, it's the combination of these following properties that make copper the industry standard choice.
