-- What we usually call a 'cable' has more than one conductor in it. At least

two or three, and sometimes hundreds.

-- Each and every conductor is covered by its own plastic or rubber 'jacket',

to prevent its touching any of the others.

-- Any conductor in the cable that's expected to carry appreciable current must be

extra thick, in order to keep its resistance low and avoid heating.
