When copper conductor is used, what may other lightning protection components be?

When using copper conductors in a lightning protection system, it is common practice for other components of the system, such as grounding electrodes, bonding strips, and down conductors, to also be made of copper. This is primarily due to the electrical conductivity and corrosion resistance properties of copper, which are crucial for the effective functioning of the system.

Using copper for all components helps maintain a consistent electrical potential throughout the system and minimizes the risk of galvanic corrosion that can occur when dissimilar metals, such as steel or aluminum, are used together with copper. Furthermore, having all components made from the same material simplifies installation and maintenance, as the properties remain uniform.

The electrical performance, longevity, and reliability of the lightning protection system greatly benefit from this choice, as copper is known for its excellent conductive capabilities and durability under various environmental conditions.
