OC-ETP® Copper busbar in electrical applications requires several key electrical and mechanical properties which include high electrical conductivity, good strength, good formability and surface flatness. These key features rely greatly upon the quality of raw material and consistency of production process. Through a state-of-the-art production process specifically designed for copper busbar production, OC-ETP® is cast from the highest purity copper cathode available from mines and smelters (grade “A” LME registered brand). The purity of the raw material and the high quality production process make OC-ETP® an excellent choice for all technical and economical solutions relating to electrical applications requiring copper busbar and busduct. In addition, OC-ETP® also offers excellent thermal conductivity, perfect for heat exchange applications, and ideal where limited space is important for e.g. CPU-heatsinks.
Electrical conductivity of any electrical conductor is dependent upon the purity of conductor. OC-ETP® is cast from pure copper cathodes with a purity of 99.99 %. This high purity of raw material enables OC-ETP® to achieve an electrical conductivity 101% IACS (International Annealed Copper Standard).
Cu-ETP is used for most conductors and fabricated electrical components.
