Stranded copper

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.

A stranded copper 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.
