The low-resistance grounding module is a non-metallic material-based grounding body composed of non-metallic minerals with good conductivity and chemical stability, metal ground rods, electrolytes and humectants.

round performance and characteristics

2. Working grounding and protective grounding for valuable precision instruments, computer room equipment, postal and telecommunications program control equipment, radio and television equipment, and electronic medical equipment;

2. When several modules are embedded in parallel, the module spacing should not be less than 4.0 meters. If the conditions are not allowed, it can be appropriately reduced. At the same time, the value of the module utilization coefficient should be reduced when the amount of module is calculated.

5. During backfilling, it should be sprinkled with water in an appropriate amount, tamped in layers and watered again after backfilling. Meanwhile, the grounding resistance should be measured after the module is fully hygroscopically absorbed (72

2. External force should be avoided to damage modules during transportation and installation;
