Copper Foil Flexible Busbar For Medium Frequency Melting Furnace & High Power Welding Machine

The Technical Parameters For Copper Foil Flexible Busbar：

• Material: T2 High Purity Copper Foil (≥99.95%)
• Molding Process: Polymer Diffusion Welding, Integral Forming
• Surface Treatment: Bare Copper / Tin Plating / Nickel Plating
• Insulation Option: PVC Heat Shrink Tube / Silicone Rubber Sleeve
• Working Temperature: -40℃ ~ 180℃
• Feature: Low impedance, high current, vibration resistance, thermal compensation
• Custom Service: Size, shape, hole position, insulation all customizable

• Ultra-low Resistance & Stable High-current Output: Adopts 99.95% high-purity copper. Laminated flat structure provides larger heat dissipation area, lower temperature rise and less power loss.
• Vibration & Thermal Deformation Compensation: Flexible laminated structure absorbs mechanical vibration and thermal expansion/contraction. No terminal cracking or bolt loosening.
• Excellent Fatigue Resistance for Frequent On-off Working: Adapt to frequent arc striking/extinguishing and instantaneous impact current of welding equipment.
• Custom Size & Easy Installation: Customizable length, width, thickness, hole position and bending shape.
• Harsh Environment Resistance: Optional tin/nickel plating anti-oxidation treatment, flame-retardant silicone insulation or heat-shrink sleeve.

Application Scenarios

1. Medium Frequency Melting Furnace

Medium-frequency melting equipment generates high heat during long-term operation, accompanied by obvious thermal expansion and mechanical vibration. Rigid copper bars are easy to crack and loose. Zipeng flexible copper busbars are widely used for flexible connection between furnace transformer, inverter module and rectifier unit.

2. High Power Welding Machine

High-power welding machines produce thousands of amperes instantaneous surge current during arc striking and extinguishing, with frequent current fluctuation and temperature shock. Flexible copper busbars connect the low-voltage output of main transformer, rectifier bridge and output terminals.
