Bus bar

RPK Group manufactures rigid copper bus bars, rigid aluminum bus bars, flexible laminated copper bus bars, insulated bus bars, and overmolded bus bar assemblies with plastic housings. We also produce bus bar connectors for EV battery modules, wire forms for alternators, and multi-axis bent profiles for high-density power distribution systems.

Rigid bus bars are machined or stamped from solid copper or aluminum bar stock and provide high current capacity in fixed geometries. Flexible laminated bus bars use multiple thin copper foil layers to allow movement, absorb vibration, and compensate for misalignment. They are standard in EV battery packs, inverters, and charging infrastructure, where thermal expansion or mechanical vibration must be accommodated.

Electrical bus bars are produced in electrolytic tough pitch (ETP) copper, oxygen-free copper (OFC), and aluminum alloys (typically 1100 or 6101 series). Surface finishes include tin, silver, and nickel plating to control contact resistance, corrosion resistance, and solderability.

RPK Group manufactures bus bars in facilities certified to IATF 16949. Contact our engineering team to discuss compliance requirements for specific standards such as LV214, USCAR, or IPC for your application.

RPK Group designs and manufactures bus bars for high-voltage EV applications, including 400V and 800V battery architectures. Material selection, plating, insulation, and clearance distances are engineered to the voltage and current requirements of each specific application.

Yes. RPK Group supplies bus bars for switchgear, electrical panels, UPS systems, motor drives, and renewable energy equipment. Industrial bus bars require different current ratings, plating standards, and form factors than automotive bus bars; our engineering team designs each solution to the application.
