Graphite Ground Wire
Oxygen-free hot-dip (horizontal continuous casting process) manufacturing, copper metallurgical molecular bonding, surface hot-dip tin, no chemical corrosion and galvanic effect, does not affect cathodic protection.
1. Graphite Grounding Wire Main Performance Characteristics
The grounding body is cable-shaped and made of high-carbon graphite wire. The connecting end connected to the tower is made of stainless alloy. This product is a non-metallic conductor, which is resistant to corrosion, rust, stable grounding resistance, and high-current impact without counterattack. No damage, constant resistance, high and low temperature resistance, long service life of 30 years, maintenance-free, safe and reliable. It is free from environmental and climatic conditions, easy to install, no need for electric welding, saves labor and time, saves materials, funds, energy saving, environmental protection, anti-theft, especially suitable for acidic soil, alkaline soil, swamp, hot and humid zone and beach.

3. Graphite Grounding Wire Specifications
The cross-sectional area of the cable is 20×20mm, 16×16mm, 4×4mm, 5×5mm, and the length can be processed according to the user's design requirements.
4. Graphite Grounding Wire Amount Calculation:
The amount of this product is calculated according to the amount of galvanized steel with a diameter of 10mm.
5. Installation and construction requirements:
According to the design requirements of Party A's drawings during construction.
Installation and construction under the technical guidance of the factory.
This copperweld ground wire should be installed in the shape of a mouth, and the two joints should be closed.
The connection method is lap joint, and the conductive graphite wire is wound and fastened, and the length dimension of the tower connection is 10 times of the diameter of the grounding body.
The grounding body ditch should be flat, buried with fine wet soil, layered and compacted.
Prevent sharp objects from scratching the graphite cable body, protect the cable from conduction and the leakage layer from damage.
Use steel pipe to protect the roadbed.
When the product is used in a special section, the connecting body needs to be reinforced.
Copper Clad Steel Grounding Conductors Advantage:
1. copper clad rod has strong corrosion resistance and will not come off, warp or crack. The corrosion of the grounding body of the grounding grid is reduced, and the overall operation safety of the equipment is enhanced.
2. Copper coated grounding conductor material: the copper clad steel ground wire has a thick copper layer, good conductivity, and stable electrical performance; the copper-clad steel ground rod and copper-clad steel round copper layer can reach more than 0.5mm, and the conductivity of the copper-clad steel strand can reach more than 40%.
3. The copper layer and the steel are molecularly combined, and the grounding rod penetrates the soil without breaking.
