What is the conducting cable material used in a lightning protection system?

Copper
Aluminum
Steel
Brass

The correct answer is: Copper

Copper is the preferred conducting cable material used in a lightning protection system due to its exceptional electrical conductivity, which allows it to efficiently carry large bursts of electrical energy from a lightning strike safely to the ground. Copper is also highly resistant to corrosion, ensuring that the protection system remains effective over time. Its malleability makes it easy to work with during installation, allowing for secure connections and routing along structures. While other materials like aluminum and steel may be used in some applications, they do not offer the same level of conductivity and corrosion resistance as copper. Brass typically contains copper but is less effective as a conductor and is not commonly used in lightning protection systems. Thus, copper remains the standard choice for ensuring safety and efficacy in lightning protection systems.
