copper clad aluminum cable
Copper clad aluminum (CCA) cable represents a revolutionary advancement in electrical conductor technology, combining the superior conductivity of copper with the lightweight properties and cost-effectiveness of aluminum. This innovative cable consists of an aluminum core that is metallurgically bonded with a copper outer layer, creating a unified conductor that delivers optimal performance. The copper coating, typically comprising 10-15% of the conductor's cross-section, provides excellent electrical conductivity at the surface where high-frequency signals travel, while the aluminum core offers structural support and weight reduction. CCA cables are engineered to meet diverse industrial and commercial applications, particularly in telecommunications, power distribution, and electronic systems. Their unique construction allows for enhanced current carrying capacity compared to pure aluminum conductors, while maintaining a significantly lower weight profile than pure copper cables. The manufacturing process ensures a permanent molecular bond between the two metals, preventing separation and maintaining consistent electrical properties throughout the cable's lifespan. These cables are available in various sizes and configurations, making them suitable for both indoor and outdoor installations, and they comply with relevant international safety and performance standards.
