Products Description
Definition of copper-clad steel flat steel: It has the advantages of thick copper layer, low resistance, strong resistance, convenience, and good electrical connection performance. It is widely used in grounding devices of power transmission and transformation and communication lines, power stations, buildings and antennas. It is also It can be used in the grounding system of electronic equipment such as computers, and can be combined with air terminals (lightning rods, lightning protection wires) and down conductors to form a lightning protection grounding device.
Copper-clad steel grounding conductors are produced using a cold-rolled and hot-drawn process, which overcomes the shortcomings of the electroplating method and the casing coating method such as poor bonding force. Copper-clad steel composite materials have good electrical conductivity and high mechanical strength, especially the outer copper layer has good properties, so they have been widely used in grounding devices. Current relevant standards stipulate that grounding conductors can be made of copper-clad steel composite materials.
Features and advantages:
1. Manufacturing process: The cold rolling and hot drawing production process is used to achieve metallurgical welding between copper and steel. It can be pulled out like a single metal without any detachment, peeling or cracking.
2. Safety: The composite interface adopts high-temperature welding, and there will be no corrosion on the joint surface; the surface copper layer is thick (average thickness is greater than 0.3mm), has strong resistance, and has a long service life (more than 30 years), reducing the labor intensity of maintenance.
3. Good electrical performance: The excellent electrical conductivity of the surface copper material makes its resistance value much lower than that of conventional materials.
4. Wide range: This product is suitable for grounding construction under different soil moisture, temperature, PH value and resistivity changes.
5. Connection: Use connecting pipes or hot-melt welding to ensure strong joints and good stability.
6. Easy installation: Accessories and easy installation can greatly improve the construction speed.
7. Improve grounding: The connection transmission method can go deep into the ground 35 meters to meet the low resistance requirements of the occasion.
8. Low construction cost: Compared with the traditional construction method of using pure copper grounding rods and grounding strips, the cost has dropped significantly.
Technical Parameters:
1. Copper layer thickness ≥0.3mm
2. Tensile strength ≥600N/mm
3. Straightness error ≤0.5mm/m
4. Plasticity of the copper layer: When the grounding rod and grounding round wire are bent at 30 degrees, there will be no cracks on the inner and outer edges of the corners.
Copper layer bonding: After adhesion testing, except for the copper layer peeling off in the jaws of the vise, the remaining copper and steel are well bonded, indicating peeling.
Main technical parameters:
1. Thickness of copper layer≥0.3mm
2. Tensile strength≥600N/mm2
3. Straightness error≤0.5mm/m
4. The plasticity of the copper layer: when the ground rod and the ground round wire are bent 30 degrees, there will be no cracks on the inner and outer edges of the corner.
Bonding degree of the copper layer: After the adhesion test, except for the peeling copper layer at the jaws of the vise, the other parts of the copper and steel are well bonded, which is the phenomenon of peeling.
