OC-ETP

CU-ETP®

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

Overview

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.

The main difference is the chemical composition, and the electrical performance is higher. Also, depending on the grade:

 

  • Grain Size – OC-ETP ® has a smaller grain size.
  • Hardness – OC-ETP ® is a harder
  • Tensile Strength – OC-ETP ® is tougher

 

One possible negative effect of the above three items could be ‘Orange Peel’, a minor cracking in the copper surface during the bending that could affect the current flow/power flow.

OC-ETP® vs. Cu-OF, we use a Spectrometer to determine the difference of copper purity in materials. OC-ETP® has a slightly higher Oxygen content than Cu-OF.

 

Cu-OF does not have Oxygen in the copper, should basically have higher purity and therefore, its conductivity should be higher than OC-ETP®.

 

However, due to the proper production process for OC-ETP®, it achieves equivalent conductivity to Cu-OF, but with superior mechanical properties.

 

Cu-OF is suitable as straight Bar or can only be bended through annealing process which will alter the original mechanical properties resulting in the less strength of the Bus Bar.

 

OC-ETP® vs. Cu-Other – The less purity 0.02% of Cu-Other reduces conductivity due to a critical the impurity elements in the copper. The cost saving of purchase is only 1 % while the resulting watt loss is as high as 12 % which impacts on the whole service life of the Bus Bars.

No, the brightness and shininess are the result of the reduction of material after cold drawing.

ICT & Data Center

Progression of the internet of things (IoT), growing AI capabilities and the rollout of 5G networks are among the main technology-related drivers that are leading to near-exponential growth in the amount of data to be processed. Accordingly, data centers, where data is stored and processed, are now critical infrastructures in the field.

Marine

Most of all consumer goods have spent some part of their journey on a ship, making the marine industry one of the primary drivers of globalization and trade. Vessels move cargo around the world in far greater volumes more efficiently, safely, and with a lower environmental impact than any other mode of transportation.

Healthcare

The health care industry, or medical industry, is a sector that provides goods and services to treat patients with curative, preventive, rehabilitative, or palliative care. The healthcare industry is composed of establishments devoted to the prevention, diagnosis, treatment, and rehabilitation of medical conditions.

Electronics

The electronics industry is one of the largest global industries because of enormous array of electronic devices produced by the industry. Products are primarily assembled from metal-oxide-semiconductor (MOS) transistors and integrated circuits, and printed circuit boards (PCB). The electronics industry consists of various sub-sectors. The major driving force of the entire electronics industry is the semiconductor sector. The output products are electronic equipment’s, communication equipment, medical monitoring devices, navigational equipment, and computers.

Mining and base metal refinery

There is a continual projected growth in base metal mining and refineries because more metal demand use in global manufacturing. The increasing use of more elements drives the uneven distribution of mineral deposits and metal extraction facilities across the globe. However, material criticality has become an issue of concern for governments, manufacturers, and other stakeholders because of uneasiness surrounding supply risks and environmental impacts. Thus, the supply is dependent on both regulatory and economic factors.

Renewable Energy

"Renewable Energy: A Sustainable Driver of the Copper Industry" The world economy is on the track for a low-carbon and sustainability-focused growth mode, an increasing number of nations around the world are adopting clean energy as a priority for their energy strategies.
