The difference between cable and wire

In fact, there is no strict boundary between "wire" and "cable". Generally, products with a small number of cores, small product diameters, and simple structures are called wires, those without insulation are called bare wires, and the others are called cables; those with a larger conductor cross-sectional area (greater than 6 square millimeters) are called large wires. Small (less than or equal to 6 square millimeters) are called small wires, and insulated wires are also called cloth wires.
