Our flat insulated solid copper busbar is an electrically conductive material designed for high current transmission. The core is made of high-purity copper (e.g. T1/T2 oxygen-free copper) covered with an insulating layer (e.g. PTFE, polyimide film or fiberglass composite), which provides a compact structure, high current-carrying capacity, and excellent heat dissipation performance. Its design reduces skin effect and eddy current loss, and is suitable for complex electromagnetic environments and high-temperature scenarios.

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).
