What is a cable? Fix it if you know it.

It is usually a rope-like cable twisted by several or several groups of steel wires [at least two in each group]. Each set of wires is insulated from each other and usually twisted around a center. All wires and cables coated with high insulation coating refer to materials used for power, communication and related transmission purposes. There is no strict cable between "wire" and "cable"

Boundaries. Usually, products with few cores, small product diameter and simple structure are called wires, those without insulation are called bare wires, and others are called cables; A conductor with a larger cross-sectional area (greater than 6 square millimeters) is called a large conductor, a conductor with a smaller cross-sectional area (less than or equal to 6 square millimeters) is called a small conductor, and an insulated wire is also called a distribution wire.
