This earth rod is used for the power networks earth system. The copper coating made by electrolytic process gives a resistance to corrosion as well as a good conductivity. The reference standards are EN 50 164-2 and EN 62 561-2. The brass clamp with stainless steel bolts is designed to establish a connection between the earth rod and the conductor. The cable can be fixed radially or axially through the "U" bolt clamp. The round connection clamp can be in bronze. These brass driving spikes and heads are designed to protect the earth rod during the installation. They enable to preserve the copper coating and its technical features. The taper coupling is made of brass. It allows the junction between two unthreaded earth rods with nominal diameter 16mm.
