Can main size aluminum conductor be used in tree lightning protection?

In the context of lightning protection systems, using aluminum conductors for tree protection typically is not considered safe or effective. While aluminum is a common conductor material, it has higher resistance compared to copper and can be more prone to corrosion, especially in outdoor settings with varying environmental conditions. This can lead to a diminished ability to effectively carry the lightning current, which is critical for safely diverting it into the ground.

For properly designed tree lightning protection systems, copper conductors are often preferred due to their lower resistance and better conductivity, which ensures a more reliable pathway for lightning currents. Therefore, it is important to adhere to industry standards and guidelines that highlight the limitations of using aluminum in such applications. This reasoning underscores why the assertion that main size aluminum conductor can be used in tree lightning protection would not be correct.
