Busbars for High-Voltage Applications

Cross sections up to 300 mm2 with expertise in complex bending geometries

Our aluminum and copper busbars provide comprehensive solutions for demanding high-voltage applications. The flat rectangular profile delivers superior heat dissipation and higher current capacity while fitting into tight installation spaces. Manufactured with sustainable low-carbon aluminum and PA 11 insulation material, our busbars achieve significant weight reduction with the lowest possible emissions – advancing both performance and environmental responsibility.
