Stranded tinned 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.

Tin is a useful plating for copper because it not only helps to boost copper’s properties, it also helps the wire to last much longer and counter acts against oxidation. Tin also helps to strengthen the copper wire, making it more resilient to breakage or lost connections, at the same time boosting the coppers conductivity.

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.
