Copper Bus Bar with PA12 Extrusion for EV Battery Applications

Manufactured from T2Y2 hard copper with at least 98 percent IACS conductivity, the copper busbar offers high mechanical stability and reliable performance under vibration and thermal cycling. Chamfered edges reduce electric field concentration and creepage risks. PA12 insulation provides strong dielectric protection and stable performance at 105 to 125 degrees Celsius, making it suitable for EV battery packs and energy storage systems.

  • Edge Type: Full round edge, round corner, square corner
  • Plating: Tin plating, nickel plating
  • MOQ: 100 (Negotiable)
  • Size: Customized
  • Conductor Material: T2Y2 copper
  • Insulation: PA12 Extruded Layer

Rigid copper busbar provides uniform, void-free insulation with excellent temperature, oil, and vibration resistance. Its thin, halogen-free PA12 extruded layer delivers high dielectric strength and UL94 V-0 flame resistance while supporting efficient heat dissipation. With robust mechanical strength and reliable insulation performance, the insulated busbar is well suited for high-voltage connections in EV battery packs and energy storage systems.
