Modern automobiles are equipped with multiple electrical components, all requiring a stable and efficient power supply. Busbars play a vital role, connecting the battery to these various components and ensuring a smooth transmission of electricity.
For busbars to perform their function safely over the entire service life of the vehicle, high-quality insulation is essential.
In July 2011, years before the global rise of e-mobility, we commissioned the first Rosendahl busbar insulation line. Since then, these high-performance “flat cables” have gained significant importance. They have become an integral part of e-vehicles, facilitating the conduction and distribution of power within electrical systems.
Their main advantage lies in their ability to handle higher currents than traditional cables, resulting in a substantial reduction of power losses. Their distinctive flat shape is optimized for efficient use of the space available within a vehicle’s electrical construction.
Processing busbars is more challenging compared to traditional cables with round cross-sections.
Even minor deviations can noticeably impact wall thickness distribution. Therefore, precise control from pay-off to take-up is crucial for maintaining quality. Every line components must be precisely calibrated to achieve seamless production with high-quality output.
With our busbar insulation solution, we pay special attention to the conductor cleaning process before extrusion, and proper cooling afterward. That way, we ensure a high level of adhesion between the aluminum conductor and the insulation layer, which, alongside uniform wall thickness, is a primary quality criterion for the final product.
