The National Electrical Manufacturers Association (NEMA) published ANSI/NEMA WC 67-2012, “Standard for Uninsulated Conductors Used in Electrical and Electronic Applications.” The standard covers the following uninsulated conductors:

  • Single-end (solid) and stranded
  • Coated and uncoated copper
  • Coated copper alloy
  • Coated copper-clad steel
  • Aluminum conductors
  • Thermocouple extension conductors

These conductors are used primarily in insulated wires for aerospace, electrical, electronic, and other high performance applications.

“WC 67-2012 provides the requirements for high-reliability conductors used in aerospace, electrical, and electronic equipment,” said Kevin Coderre, technical director, RSCC Aerospace and Defense, and NEMA 7HW aerospace technical committee chairman. “The 2012 revision will be referenced by a battery of high performance wire and cable standards. Specifically, the revision adds silver-coated copper and silver-coated copper alloy requirements to bring the document in line with the current state of practice of the industry.”
