CopperClad Composite Conductors (CCC)



  • Strength – The steel component of the CCC provides a higher tensile strength. Additionally, it is a lighter weight product compared to solid copper.
  • Ampacity – CCC conductor offers higher ampacity for the same wire size as standard CopperClad strand.
  • Fatigue resistance – The steel cores within the strands of CopperClad allow the composite conductors to perform better than solid copper under stress.
  • Corrosion resistance – The EHS CopperClad wire component has the equivalent rust-resisting life of an all-copper wire of equal size.
  • Theft resistant – With a steel core permanently bonded to a thick copper exterior, the composite conductors offer less scrap value, discouraging theft and leaving the electrical system intact.


  • Neutral messenger for aerial cable
  • Catenary messenger
  • Grounding and power conductor for electrified railroads
  • Electrical conductor for utilities

CopperClad Copper Composite (CCC) conductor provides the designer flexibility of strength and conductivity. By manufacturing the conductor with varying proportions of
hard drawn copper wire and 30% conductivity Extra High Strength (EHS) CopperClad wire, these characteristics can be achieved.
