Anyang lightning protection company-how to do lightning protection grounding for distribution lines?

In fact, there are strict requirements and standard designs for lightning protection and grounding in the distribution room. I can only say here, for reference only, not as a basis for construction.

Generally, before the civil construction of the distribution room, the grounding grid should be buried. First, the grounding piles are driven every 5 meters (galvanized steel pipes with a diameter of 10 cm or more, and driven vertically into the ground more than 2.5 meters), and then the grounding piles are welded into a grid structure with 5 cm galvanized flat steel, and a circle is arranged along the periphery of the distribution room. Welding should be lap welding, not butt welding. The grounding grid is located 50 cm below the ground. Code for installation of building reinforcement and welding of grounding grid. The grounding wire of the equipment in the distribution room is also welded firmly with the grounding grid. The grounding resistance of the grounding grid should be less than the specified value (it seems to be 2 ohms). That's about it.
