When manufacturing CCA BUSBAR, there are several key aspects to focus on to ensure product quality and production efficiency:
- Raw material selection
Aluminum core wire: Aluminum core must have good electrical conductivity and toughness, usually high purity aluminum or aluminum alloy is chosen as the base material.
Copper strip quality: The copper layer needs to be made of high purity copper material (e.g. oxygen-free copper) to ensure excellent electrical conductivity and corrosion resistance.
- Technology
Cladding and welding technology:
Ensure that the copper strip and aluminum core are firmly fused through metallurgical bonding to avoid delamination or cracks.
High precision equipment is used to ensure uniform thickness of the copper layer during the cladding process.
Drawing and annealing:
Keep the ratio of copper to aluminum constant during the drawing process to avoid breakage of the copper layer.
The annealing process requires temperature control to prevent the material from becoming brittle or degrading in properties.
- Dimension and tolerance control
Strictly control the outer diameter and copper layer thickness of CCA BUSBAR according to the standard requirements.
Use high precision measuring equipment to ensure that the wire diameter error is within ±0.003mm or 1%.
- Surface quality
Ensure the surface is smooth and clean without dents, cracks or exposed aluminum.
For finer wires, use a magnifying glass (no more than 10 times) for inspection.
- Electrical Performance Test
Test electrical conductivity to ensure compliance with design requirements.
Confirm the performance of high frequency signal transmission and verify whether the skin effect meets the application scenario.
- Environmental control
Anti-oxidation measures:
Avoid oxidation of the aluminum core and copper layer during the production process, and operate under a protective atmosphere (e.g. nitrogen) if necessary.
Clean production environment:
Avoid contamination of material surface by impurities.
- Product Inspection
Conduct product quality inspection according to national or industry standards (e.g. ISO 9001), including:
Appearance inspection.
Dimensional measurement.
Copper layer thickness check.
Electrical property test (conductivity, tensile strength, ductility, etc.).
- Equipment Maintenance
Maintain the cleanliness and accuracy of the cladding welding equipment and drawing machine.
Regularly check the performance of the equipment to prevent product defects due to equipment problems.
- Production efficiency and cost control
Optimize the process flow to improve production speed.
Reasonable use of raw materials, reduce waste, reduce production costs.
- Safety and environmental protection
Ensure the operation safety of workers and provide necessary protective measures.
Comply with environmental protection regulations and deal with waste and emissions in the production process.
By taking the above precautions, we can improve the production efficiency and product quality of CCA BUSBAR, and at the same time meet the needs of customers and the industry.
