The conductors are the most commonly used source for overhead power lines, which should be protected from damage to retain a steady power source. The two most used metals for the conductors are aluminum and copper, with copper being the standard for electrical conductivity. A benefit of copper is that it is more conductive than aluminum, as aluminum is only about 61% as conductive as copper.
