Home Products Copper Profiles & Specialities PA12 Insulated Copper Busbars PA12 Insulated Copper Busbars Boosting efficiency in electric vehicles and beyond. Contact Us Contact Luvata has succeeded in developing a high-adhesion PA12 insulated copper busbar, that is specifically designed for the growing EV market and found to be very effective in other applications as well, such as data center cooling. Our polyamide PA12 insulated busbars are made from oxygen-free copper (Cu-OF), which offers superior conductivity, bendability, and cold formability, reducing the risk of edge cracks. The absence of oxygen allows more current to pass through the same conductor size, making it ideal for EV applications. Applications Battery modules Onboard charging Power inverters DC-to-DC converters Auxiliary connectors Data centers High-power connections Perfect Solution for the E-mobility Industry & Beyond PA12 Insulated Copper Busbars Large EV battery packs need materials that can handle higher voltages, ensure thermal conductivity, and fit in confined spaces while being safe, cost-efficient, and reliable. Luvata’s PA12 insulated copper busbars meet these needs, offering better thermal and electrical performance and increased reliability compared to rigid stamped busbars. Luvata also provides busbars as cables and precision-bending products to suit customer requirements. The design of busbars and interconnect systems is vital for EV battery performance. Luvata’s high-adhesion PA12 insulated copper busbars withstand nearly 30kV and serve commonly in battery connections. PA12 Insulated Copper Busbars Key Benefits improved flexibility, reduced space requirements, enhanced thermal performance, and increased reliability over ridged stamped busbars high-temperature resistance ensures safe and reliable operation during charging and under high-voltage loads reduces the forces on bolted and welded connections by designing them with unique bends that allow thermal expansion in directions opposite to the connection points more flexible than other stamped busbars, allowing for greater misalignment between connection points can withstand voltages above 1000V Manufacturing Locations Europe Pori, Finland PA12 Insulation Material PA12 is ideal for busbars due to its excellent insulating properties and adhesion with oxygen-free copper. It offers durability, bendability, wear resistance, low water absorbency, dimensional stability, and chemical resistance. These qualities make PA12 suitable for harsh environments, ensuring reliable performance in the presence of oil and fuels. In EV power systems, PA12 insulated busbars provide flexibility, reduced space requirements, and the ability to handle misalignment, reducing stress on connections. Designing & Implementing PA12 Insulated Copper Busbars Design Flexibility Busbars in EVs are typically made from thick, flat, rigid copper wire, bent and twisted as needed. PA12 insulated copper busbars, available in a soft temper, allow easy forming and bending into sharp shapes while maintaining insulation adhesion. They can be joined using various welding and brazing methods, making them ideal for manufacturing processes requiring extreme deformability. Using pre-bent components lowers system costs by eliminating a processing step. Precision & Quality PA12 insulated copper busbars offer superior flexibility, reducing rework after assembly, especially with misaligned components. Proper design ensures effective current carrying without exceeding safe temperatures. Precision in implementation and uniformity in quality and size are crucial, aligning with Luvata’s commitment to its customers. Document Library Why Luvata?
