Product description
Graphene grounding wire Graphite grounding wire is cable-shaped, made of high-carbon graphite wire, and the connection end connected to the tower is made of stainless alloy. This product is a non-metallic conductor, corrosion-resistant, rust-free, and stable grounding resistance. , High current impact, no counterattack, no damage, constant resistance, high and low temperature resistance, long service life of 30 years, maintenance-free and reliable. The use is not controlled by the environment and climatic conditions, easy to install, no electric welding, labor and time saving, material saving, cost saving, energy saving, environmental protection, anti-theft, especially suitable for acidic soil, alkaline soil, swamp, hot and humid zone and beach use.
Main technical indicators of graphite grounding wire
1, solid resistivity: 0.06Ω.m
2, impulse current tolerance: (200KA) ΔR≤0
3. Power frequency current tolerance: ΔR≤0
4, high temperature performance: 300℃
5, low temperature performance:- 60℃
6, Compressive strength: ≥1200Mpa
7, Tensile strength: ≥1200Mpa
8, Graphite grounding wire is woven, which is different from metal materials, which will cause creep during seasonal dry cracking of the soil, sedimentation of melting water, freezing, and melting of frozen soil
Under the circumstances, the contact resistance between the flexible graphite grounding wire and the soil is always kept at a stable low value.
Good dynamic and thermal stability under high current impact, and low temperature rise to avoid soil sintering. The flexible graphite grounding wire is conductive and non-magnetic, and its dispersion length is much longer than the steel-type grounding body under the impact of power frequency and lightning high frequency, which can double the power frequency grounding resistance of the earth network. This is the reason why graphite grounding wires are used as ground grids for large projects such as large power plants and substations. Graphite grounding wire installation and construction requirements: strictly follow the drawings, and there is no drawing to communicate with the ordering unit.
2. The grounding wire should be installed in a mouth shape with two joints closed.
3. When the tower is connected, the length scale is 10 times the diameter of the grounding body.
4. The grounding body trench should be flat, buried with fine wet soil, and compacted in layers.
5. Prevent sharp objects from scratching the graphite cable body, and protect the cable body's conduction and leakage layer from damage.
