Copper Bus Bar -Extruded Rigid Busbar

Insulated busbars are extensively employed in electric automotive applications. Battery busbars feature PA12 insulation capable of withstanding 5000V AC voltage. These busbars can be manufactured up to 3 meters in length, allowing for continuous bending with high precision.

  • Material: 99.9% T2 Copper
  • Edge Type: Full round edge, round corner, square corner
  • Plating: Tin plating
  • Size: Customized

The extruded copper busbar is widely used in electric automotive now.
