The role of ground rod in lightning protection system

The ground rod plays a vital role in all lightning protection stages. The actual structure is as follows:
Main rod: The ground rod is made of high-quality cold-drawn steel, and copper is cast outside with professional equipment (thickness is 0.3~0.5MM, copper content is 99.9%) to ensure good electrical conductivity and impact toughness. Has good corrosion resistance properties.
Connecting pipe: The middle of the rod and the rod can be connected by a copper connecting pipe, which has a very good practical effect of rust prevention. The rod is in close contact with the rod, and when the ground rod is driven into the ground or the push drill is used to drill into the ground, the driving force immediately acts on the ground rod. Divided into flange connection and non-threaded connection.
Pusher head: Made of high-toughness carbon steel, it can ensure that the push force is successfully penetrated into the ground.
Aluminum alloy tip: ensure that it can be driven into the ground under the premise of complex engineering geology.
The copper-clad steel grounding rod often plays a role in the lightning protection system. The copper-clad steel grounding rod is used for the vertical grounding body in the grounding grid. The grounding device has a vital function in all lightning protection systems. It directly affects all lightning protection systems. The actual effect of direct lightning protection of the lightning system is based on lightning protection grounding/lightning conductors and other lightning-induced equipment, and then leaks into the ground according to the grounding grid. In overseas countries, copper-plated ground rods (copper-clad steel ground rods) have long been used to replace galvanized round steel, precisely because the actual effect of copper-plated ground rods is many times higher than that of galvanized round steel. The ground rod is made of 99.99% electrolytic nickel electroplating process to the surface of the stainless steel plate, the degree of fusion is improved, there is no gap, and all bending is not easy to cause the copper layer to be detached, and because the surface of the round steel is high-purity electrolytic method red copper, so copper plating is grounded. The conductivity of the rod is comparable to that of pure copper, and it is the preferred raw material for grounding devices in power installation projects, petrochemical engineering projects, and communication majors.
FLUXWELD exothermic welding is used for the connection between copper-clad steel ground rods and wire connectors. The actual effect is better, so that the grounding system is completely under the protection of copper, and it can truly become a maintenance-free grounding protection device, which greatly improves the service life of its service items. .
