What is the key benefit of using exothermic bonding in lightning protection?

The key benefit of using exothermic bonding in lightning protection is that it creates a permanent bond with low resistance. This method utilizes a chemical reaction to generate high temperatures, which allows for the fusing of metals, typically between copper and other conductive materials. The resulting bond is highly conductive and has very low resistance, making it extremely effective for lightning protection systems.

This low-resistance bond is crucial in lightning protection, as it ensures that the electrical energy from a lightning strike can be efficiently conducted away from structures, minimizing the risk of damage. A permanent bond also means that the integrity of the electrical connection is maintained over time without the risk of loosening or corrosion that can occur with other bonding methods.

While aspects such as cost, installation speed, and ease of removal can be considerations in choosing bonding methods, the primary advantage lies in the strength and conductivity of the bond created through exothermic bonding, which is vital for the efficacy of lightning protection systems.
