Grounding Method for Static Electricity Ball Grounding Wire
Grounding Wire Method: The grounding wire must not be connected to a high-voltage grounding wire. ① If there are grounding terminals such as grounding stakes, grounding flat irons, or grounding busbars on site, the grounding wire can be directly connected. ② If there are no grounding terminals on site, an static electricity rod or metal angle iron can be driven into the ground to a depth of about 1 meter, and then the grounding wire can be connected. (For example, use a 16mm thick steel bar, a 4*40mm flat iron, or a 4*4*40mm angle iron driven into the ground to a depth of more than 1 meter.) (Note: According to GB12158-2006 General Guidelines for Static Electricity Accident Prevention, the grounding resistance should not exceed 100Ω.) It can also be connected to the steel reinforcement of the building structure, metal doors and windows, or metal pipes.
Installation Method: 1. Use an impact drill to drill three 12mm diameter holes on the mounting surface (if the expansion bolts are M8, use an M12 impact drill bit). After drilling the holes, use expansion bolts to fix the base to the ground.
