[CuAc13] The future of electrical conductors

Advanced electrical conductors can revolutionize our lives, enabling billions of dollars in energy savings and facilitating a transition to an electric society. Nanocarbons present a unique opportunity for developing advanced conductors for electrical power, communications, electronics, and electric machines. In this webinar, the major research progress in this field will be presented. The presenter will also elucidate the competitiveness and implications of advanced conductors with respect to conventional ones and describe their materials science, properties, and characterization. Finally, he will propose several areas of future research for advanced electrical conductors.

Advanced Electrical Conductors: An Overview and Prospects of Metal Nanocomposite and Nanocarbon Based Conductors

Questions received during the webinar dd April 21, 2021

  1. Have you heard of composite conductors combined aluminium with carbon nanotubes or graphene?
  2. Can you provide some information about the ampacity of the hybrid conductor made of copper and nanofiber?
  3. When will these alternatives be ready and economically viable?
  4. Today is it possible realize a stator or rotor winding with CNT-copper or graphene-copper for having a greater conductivity?
  5. Can we have information about the producers of these conductors?
  6. I have a question about the mechanical properties of advanced electrical conductors. Since these conductors are often fabricated in small size, what is the best mechanical experiment for obtaining their mechanical properties such as strength?
  7. Have you compare superconductors with Graphene/CNT-copper? Or is there any comparison for that?
  8. As a fire safety engineer what research has been conducted on these new combinational materials for the building environment?
  9. When do you estimate enhanced, and commercially viable, Cu/CNT conductors will be available for use in electrical machines such as motors and transformers?
  10. In order to use these conductors to build electric motors, what are the magnetic characteristics?
  11. I'm in the land High voltage industry. We produce conductors with Copper. Is there today already existing copper Alloy grade with Nanocarbon tube which can already be used ? is there already Conductor maunfactured with theses grades and if yes what are the results?
  12. What do you know about what is happening in China? Any performance numbers there?
  13. What is the max length/ diameter of a CNT copper wire and what is the production method today? All conventional production method are not capable to be applied. How to apply to mass production?
