MATERIAL DEFINITION
Electrolytic copper busbars are the most critical components of industrial electrical panel manufacturing and high-voltage power distribution facilities. Offering 99.90% purity, Cu-ETP copper busbars in Point Metal A.S. stocks deliver maximum safety with 101% IACS electrical conductivity and radiused corners to prevent overheating and arc discharges.
Copper busbars possess high current carrying capacities depending on their cross-sections (such as 20x3 mm, 30x5 mm, 40x10 mm, 50x10 mm, 100x10 mm). Tinned copper busbar options are also widely preferred in transformer connections and switchgear facilities to minimize contact resistance loss.
