Product Description:
A grounding module is a grounding electrode primarily composed of conductive non-metallic conductor materials. It consists of non-metallic materials with good conductivity and chemical stability, a metallic grounding electrode, an electrolyte, and a hygroscopic agent. Depending on the manufacturing process, there are two main types: ordinary pressing and firing. Compared to the former, the latter has many unique functions such as good compressibility, resilience, low stress, high relaxation rate, excellent water absorption and moisture retention, oil absorption, corrosion resistance, and high anisotropy of thermal and electrical conductivity. Its excellent stability allows its grounding resistance value to remain unchanged for a considerable period of time, which is unmatched by traditional grounding materials. The raw material for this product is graphite, which does not pollute the environment and is an environmentally friendly product. Performance Characteristics:
1. Uses chemically stable non-metallic conductor materials as the conductive medium of the module, ensuring its conductivity is unaffected by seasons.
2. Moisture-absorbing and moisture-retaining, maintains effective contact with the soil, and has low grounding resistance.
3. Effectively reduces the grounding resistance of the grounding grid in areas with high soil resistivity.
4. Resistant to high power frequency and impulse current surges, with stable resistance.
5. Corrosion-resistant, non-toxic, long service life, and easy to install.
6. Can withstand temperatures as low as -40℃, making it suitable for cold northern regions.
Construction Method:
1. The YBD-02m grounding module is horizontally buried, with a burial depth generally between 0.8m and 2.5m.
2. The module spacing should be no less than 3m (depending on GB50057-2010 lightning protection specifications or site conditions; using a resistance-reducing agent will yield better results). 3. When the module cores are connected in parallel or to the ground wire, welding is mandatory. The weld length of the grounding device should be twice the width of the flat steel and six times the diameter of the round steel.
4. Remove weld slag from the welded joints and apply anti-corrosion conductive paint or wrap with YBD anti-corrosion long-lasting grounding resistance reducing agent.
5. When backfilling, sprinkle water appropriately, compact in layers, and measure the grounding resistance value after the module has fully absorbed moisture (24 hours).
Precautions:
1. Store the modules in a certain humidity level, avoiding high temperature, dryness, and direct sunlight.
2. Handle with care during transportation and installation, and avoid mechanical damage to the modules.
3. In cold regions, the modules should be buried 0.8-1.2m below the frost line.
4. Our company can process grounding modules of various shapes (flat, cylindrical, plum blossom, trapezoidal, ring, etc.) and sizes according to customer requirements. Applications:
1. Working grounding, safety grounding, and lightning protection grounding for power plants, substations, coal mines, switching stations, high-voltage transmission lines, electrified railways, military units, telecommunications and mobile communication base stations, microwave relay stations, ground satellite receiving stations, radar stations, etc.
2. Working grounding and protective grounding for valuable precision instruments, computer room equipment, postal and telecommunications program-controlled equipment, broadcasting and television equipment, electronic medical equipment, etc.
3. Lightning protection grounding for various high-rise buildings and tall structures, scenic spots and ancient buildings, tall memorial towers, etc.
4. Lightning protection grounding for special equipment such as oil pipelines and oil and gas tanks, and warehouses for flammable and explosive materials.
