Solid copper busbar Surface Production process:

1. Raw material processing: High-purity copper rods from the continuous casting and rolling process are selected, and the oxidized layer is removed by straightening and pickling.

2. Molding processing: made into a flat cross section by drawing and calendering processes to ensure the dimensional accuracy (tolerance ±0.12mm).

3. Insulation processing:

• Extrusion/Coating: Polyimide film or glass fiber is extruded at high temperature or vacuum coated to cover the copper surface.
• Curing: Heat is applied to the insulating material to form a dense protective layer.

4. Quality testing: including conductor resistance test, insulation withstand voltage test (e.g., 20 20kV/mm), aging test.

5. Finished product packaging: moisture-proof and shock-proof packaging, part of the need for shielding treatment (such as tin-plated anti-oxidation).

Solid copper busbar Surface treatment process：

1. Plating technology:

• Tin/silver plating: Enhance corrosion resistance (tin plating thickness 10-20μm) and conductivity (silver plating to reduce contact resistance).
•  Nickel plating: enhances wear resistance and oxidation resistance, suitable for high-humidity environments.

2. Passivation treatment: chemical passivation to form an oxide film to prevent copper surface oxidation.

3. Mechanical treatment:

• Polishing/Brushing: Reduce surface roughness (Ra≤0.8μm), reduce current loss.
• Sandblasting: increases the friction coefficient, suitable for anti-slip demand scenarios.

Solid copper busbar Advantages：

1. High efficiency and energy saving:

• Compared with the cable to save copper 10-35%, power loss is reduced by more than 15%.
• Low skin effect (AC resistance / DC resistance coefficient ≤ 1.1) reduces heat.

2. High reliability:

• Insulation layer is chemical resistant (e.g. PTFE), life expectancy of over 30 years.
• Support ultrasonic welding, high connection strength, and no heat-affected zone.

3. Adaptable:

• Compact design saves space, customizable bending radius (≥10 times thickness).
• Suitable for high-temperature (110℃), high-humidity, and electromagnetic interference environments.

Solid copper busbar Application：

1. Power system: high voltage switchgear (40.5kV), substation busbar, smart grid transmission.
2. New energy:

• PV/wind power inverter, new energy vehicle battery pack connection.
• Charging pile high current transmission (support more than 5000A).

3. Industrial equipment: metallurgical furnace, chemical explosion-proof power distribution system.
4. High-end manufacturing:

• Data center server power supply (such as AI server cluster).
• Aerospace and rail transportation (lightweight, high reliability requirements).
