Stranded copper clad aluminum

The inner conductor is the heart of the cable and defines the flexibility and conductivity of a cable.  Several different materials and alloys are used to create these conductors, each with their specific applications and advantages.

Copper clad Aluminum allows cables to utilize all of the benefits that copper has to offer, while maintaining a much more affordable price tag. CCA is made by bonding a layer of pure copper onto an aluminum core. A CCA core cable obviously contains less copper than a pure copper cable, but it delivers virtually the same conductivity with only slightly higher resistance.

A stranded wire is more flexible and easier to install than a solid wire with the same cross section. Stranding improves wire life in applications where flexibility is needed. A particular cross-section of a stranded conductor gives it essentially the same resistance characteristics as a single-strand conductor, but with added flexibility.
