What Is Single Core Cable?

The answer to that question lies in the question itself. The term “single core” is used to describe cables with a single conductor. These are distinct from other types of cables, which are constructed as multicore cable types. The conductors in a single core cable may be manufactured with either copper or aluminum insulation.

Contrary to what some might think, a single core cable isn’t necessarily more or less flexible, or thicker or thinner than a multiple core cable. Those characteristics (thickness, thinness, flexibility or rigidity) typically depend on the single core cable size used for a particular application. The gauge and thickness depend on the gage of the cable. Large diameter cables are less flexible than smaller diameter ones.
