What is the difference between wire and cable?

In fact, there is no strict boundary between "wire" and "cable". Generally, products with small number of cores, small diameter and simple structure are called wires, those without insulation are called bare wires, and others are called cables; Larger conductor cross-section (more than 6 mm2) is called large wire, smaller conductor cross-section (less than or equal to 6 mm2) is called small wire, and insulated wire is also called cloth wire. However, with the expansion of the scope of use, many varieties of "cable in cable" and "cable in cable". So there is no need to strictly distinguish. In daily habits, people call household cloth wires as wires and power cables as cables.
The wire is composed of one or several flexible wires, wrapped with a light and soft protective layer; The cable is composed of one or several insulated wrapped wires, which are then wrapped with a tough outer layer made of metal or rubber. Cables and wires are generally composed of core wire, insulating sheath and protective sheath.
