Grounding clamp (grounding) or lightning protection, also known as "bar nut," this type of clamp is used to secure electrical conductors to grounding poles or grounding points, ensuring a strong and safe connection for effective electrical grounding and safety. Grounding clamps are a main component in lightning protection systems, providing a low-resistance path for lightning energy to safely dissipate into the ground, protecting buildings and infrastructure from electrical damage. These clamps are usually made of materials such as copper or brass, depending on the application.
