Busbars
Reliable and Space-Efficient Power Distribution for High-Performance Systems
Engineered from multi-layered copper or aluminum foils, our flexible busbars provide the vibration-resistant, high-current expansion required for the most demanding EV battery packs and industrial switchgear.
The typical production flow for flexible busbars includes:
Copper or aluminum selected based on conductivity and weight requirements; Matching insulation for environmental and voltage needs
Conductive foils or braided strips cut to size via laser or CNC
Conductive and insulating layers are arranged in the specified configuration
Layers are bonded under heat and pressure for structural integrity
Ends are prepared with connectors or lugs to interface with other components
Full QA testing for electrical, thermal, and mechanical properties
Tailored shapes, hole patterns, and connectors for specific applications
Flexible busbars are engineered to deliver high-current performance in compact, dynamic systems. Constructed using stacked or braided layers of copper or aluminum with insulated layers in between, these busbars are ideal for applications requiring bending, vibration resistance, and precise fitment in tight enclosures.
