Our busbars are made from oxygen-free copper (Cu-OF), which is immune to hydrogen embrittlement and ensures excellent welding properties. Typical busbar applications include switchgear, panel boards. 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. Choose Luvata for reliable, high-performance bus bar systems for copper or zinc refineries. One of the signature products developed by Intercable Automotive Solutions are our custom made high-voltage busbars manufactured to client specifications.
Specifications must be strictly followed in the installation process: the height deviation of the support points in the horizontal section is ≤3mm, and the deflection of the vertical section is ≤2mm/m; the connecting bolts are made of grade 8. 8 galvanized parts, and the M10. The most common type of copper used. With a minimum copper content of 99. 90%, and an electrical conductivity of 101% IACS, it is used in such diverse applications as electrical conductors, roofing and flashing, heat exchanger fins and tanks. The IEC 61439. According to the different material states, copper busbars are divided into hard copper busbars (TMY) and soft copper busbars (TMR).
