Copper wire inside wind turbine blades

Bare copper wire is used for internal electrical connections, including the generator windings and power distribution systems within the turbine. The metal plays a central role in the inner workings of the generator, grounds the towers from lightning strikes, and carries the electrical current where it needs to go. Copper provides the conductivity, corrosion resistance, strength and flexibility. . Copper is a vital metal in making wind power possible. . copper in the 1. onshore wind energy program has grown 30% and switchgear and connector lugs. [pdf]
