Copper-coated steel flats offer advantages such as thick copper layer, low resistance, strong corrosion resistance, high strength, and good electrical connection properties. They are widely used in grounding systems for transmission and transformation lines, communication lines, power stations, buildings, and antennas. They can also be used in grounding systems for electronic devices like computers and can be combined with lightning rods (flying conductors, lightning rods) and down conductors to form lightning protection grounding systems.
Copper-clad steel flat steel features:
Manufacturing Features of Copper-Coated Steel Flat Bars
Tungsten steel flat bars with copper cladding are produced using electroplating technology, achieving a high degree of integration between copper and steel. The outer copper layer consists of 99.99% electrolytic copper, which not only overcomes the disadvantages of galvanic reactions in the tube-cladding process but also resolves issues such as insufficient copper purity and surface copper layer inconsistencies in the hot-dip continuous casting process.
2. Copper-coated steel flat steel has excellent corrosion resistance.
The material features a thicker copper layer, composed of 99.99% electrolytic copper molecules, with an average thickness exceeding 0.25mm. Consequently, it boasts excellent corrosion resistance and a lifespan of over 50 years.
3. Copper-coated steel flat steel offers superior conductivity.
Due to the surface copper layer being composed of 99.99% electrolytic copper molecules, it boasts excellent conductivity and has a significantly lower resistance compared to conventional materials.
4. Copper-coated steel flats have a wider range of applications.
This product is suitable for various soil conditions with different humidity, temperature, and pH levels.
5. Copper-coated steel flat bar installation is safe and quick
Accessories, connected with connecting pipes or using high-speed heat-melt adhesive, offer solid joints, easy installation, and significantly enhance construction efficiency.
6. Copper-coated steel flat bar construction cost reduction
Compared to traditionally using pure copper materials for grounding, costs are significantly reduced.
Main Technical Parameters of Copper Clad Steel Flat Bars:
1. Copper Layer Thickness ≥ 0.3mm
2. Tensile Strength ≥ 600 N/mm²
3. Flatness error ≤ 0.5mm/m
4. Copper Lamination Malleability: No cracking appears on the inner and outer edges of the bend at 30 degrees when the grounding rod and grounding round wire are bent.
Copper bonding: After the adhesion test, the copper layer peeled off only at the jaw of the vice, with the rest of the copper and steel bonding well without any signs of delamination.
