Electrical Copper Bus Bar For EV Batteries Connection

Battery bus bars are widely used in electric automotive applications, with PA12 insulation rated for 5000V AC. Custom busbar can be produced up to 3 meters in length and offer precise continuous bending.

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

Product Description:

Insulated copper bus bars, also known as solid insulated systems (SIS), enhance grounding for switchboards, and busway installations. These bus bars are made from solid copper or aluminum conductors with insulation between each phase conductor and ground. They are increasingly used in electric automotive applications.


1. Mechanical production with high productivity.

2. Continuous bending with high accuracy.

3. Insulation PA12 with smooth surface, high corrosion resistance, high temperature resistance and fire resistance.

4. Long busbar can be produced. The battery busbar length can be made to 3 meters.

Bus Bar Performance:

Voltage Withstand: 5000V AC;

Tension strength: ≥500N;
