Copper content in high-voltage busbars
ETP copper, known as C11000, is widely used for busbars due to its high conductivity and affordability. In this new edition the calculation of current-carrying capacity has been greatly simplified by the provision of exact formulae for some common busbar configurations and graphical methods for others. Other sections have been updated and modified to reflect current practice. Copper Development. For the lowest possible voltage drop, we use only highly conductive copper Cu-ETP & OF-Cu for your copper busbars. We look forward to hearing from you! Copper busbars are used, among other things, as electrical connection elements in high-current technology, high-voltage technology. If you want high-power PCBs, we can deliver thick-copper PCBs for the most demanding high-current and high-voltage applications. The red circles show data from 5 electric vehicle battery busbars. The current is an estimated continuous rating and plotted versus the cross-sectional area in mm 2. Whether you are designing EV battery packs, data center PDUs, renewable energy inverters, industrial switchboards, or rail traction systems, the way you design and manufacture the copper busbar will determine.
