| Copperweld: Composite Conductor (CCC) |
|
| Copperweld® 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) Copperweld wire, these characteristics can be achieved. |

Features:
Strength
The steel component of the CCC provides a higher tensile strength. Additionally, it is a lighter weight product compared to solid copper. Combining these factors, it has minimum sag over maximum span lengths. A high and well-defined modulus of elasticity accommodates recurring seasonal temperature changes and stresses without permanent stretch.
Ampacity
CCC conductor offers higher ampacity for the same wire size as standard Copperweld strand.
Fatigue Resistance
The steel cores within the strands of Copperweld allow the composite conductors to perform better than solid copper under stress. It is less susceptible to fracture from repeated flexing and mechanical vibration
Corrosion Resistance
The EHS Copperweld wire component has the equivalent rust resisting life of an all-copper wire of equal size. CCC conductor is ideally suited for corrosive environments along seaboards, in moist foggy regions, and in industrial and metropolitan areas.
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.
Applications:
• Neutral messenger for aerial cable
• Catenary messenger
• Grounding and power conductor for electrified railroads
• Electrical conductor for utilities
