Laminated copper bus bar Production Process:

Les barres omnibus en cuivre laminé peuvent être classées en fonction de divers facteurs tels que la taille, la forme et la configuration. Certaines classifications courantes incluent :

1. Material Preparation: Copper foil/copper plate cut to required size, insulation material (e.g. epoxy resin film) cut.
2. Lamination molding: Alternate stacking of copper and insulating layers, through the hot press high temperature (such as 200 ℃ ~ 300 ℃) and high pressure (such as 20MPa) curing.
3. Welding and connection: Use molecular diffusion welding or pressure welding process to fix the contact surface.
4. Traitement de surface : Passivation treatment (anti-oxidation), tin/silver plating (enhance conductivity), epoxy coating (anti-corrosion).
5. Bending and Testing: Specialized bending machine molding, and through the load capacity, voltage resistance, temperature rise and other tests.

Avantages des barres omnibus en cuivre laminé :

• High performance:  Skin effect optimization, 53% increase in current-carrying capacity compared with solid copper rows, 10% to 20% reduction in loss.
• Light weight and environmental protection: Copper consumption is reduced by 30%~50%, in line with low-carbon requirements.
• Excellent heat dissipation: The multi-layer structure accelerates heat diffusion, and the temperature rise is 20% lower than that of traditional busbar.
• Compact structure: Compact size: 50% less space than cable, suitable for small environments (e.g. data centers).High reliability:
• High reliability: vibration-resistant, short-circuit-resistant (63kA/4s), with a life span of more than 20 years.

Laminated copper bus bar application:

• Power system: Substation main busbar, distribution cabinet busbar.
• New energy: PV/wind farm power transmission, electric vehicle battery pack connection.
• Industrial equipment: High-current equipment such as frequency converters, welding machines, machine tools, etc.
• Transport ferroviaire : High-speed rail/subway power system, signaling system power supply.
• Data Center: Efficient power distribution for server clusters.

FAQ sur les jeux de barres en cuivre laminé

Q1: What is the difference between laminated copper busbar and traditional copper busbar?
A1: Laminated structure reduces the skin effect through thin copper plate stacking, higher current carrying capacity, lower loss, and lighter weight.

Q2：What are the advantages of flexible laminated busbar?
A2: It can be bent and installed to adapt to the complex space, and can compensate for equipment installation errors, suitable for electric vehicle charging pile and other scenarios.

Q3：How to choose the insulation material of laminated busbar?
A3: Choose according to the temperature demand, such as PTFE (high temperature resistant), epoxy resin (high mechanical strength) or silicone rubber (flexible).

Q4: Key points for quality control in production?
A4：Copper purity (≥99.95%), lamination uniformity, welding strength and insulation layer dielectric properties need to be tested.

Q5: Is laminated busbar suitable for outdoor environment?
A5: Yes. With IP67 protection design and UV-resistant coating, it can adapt to humid, dusty and other harsh conditions.
