Are cables and wires made of the same material? Many friends may be confused, but in fact, there are differences between cables and wires in terms of size, structure, purpose, and so on. So what are the differences between cables and wires? Let  Fismian Group take you to learn about relevant knowledge!

1、 Cable Definition

A cable is made of several wires or groups of wires that are insulated from each other and twisted around a central wire, with a high insulation layer covering the outside. The processing of cable products starts from conductors, with insulation, shielding, cabling, and protective layers added to the periphery. The more complex the product structure, the more layers it has.

2、 Definition of wires

Electric wires are made of conductive metal wires that carry current. There are several forms of wires, including twisted or foil woven, and so on. According to the insulation condition, there are two types of wires: bare wires and insulated wires. Flexible cylindrical conductors with insulation are longer than their cross-sectional dimensions.

3、 The difference between cables and wires

1. Cables and wires are mainly composed of three parts, namely core wire, insulation sheath, and protective sheath. Electric wires are made by wrapping the outer layer of the wire with a light and soft protective layer; And cables are covered with metal or rubber outside the wires, mainly used for transmitting electrical signals.

2. Electric wires, as conductive wires that carry current, can be divided into twisted, solid, foil woven, etc. according to their form. Divide bare electricity and insulated electricity according to insulation conditions. The cable is composed of insulated conductors placed in a sheath. The surface is covered with a protective layer, mainly used for transmitting, distributing, or transmitting electrical signals. The biggest difference in appearance is that the cable size is larger and the structure is more complex, while the wire size is smaller and the structure is simpler.

3. The biggest advantage of cables is that they occupy less space and the insulation distance between lines is not significantly different. If laid underground, they will not occupy space above the ground and are not affected by environmental pollution. Power transmission is very reliable and safe, and will not cause interference to people and the surrounding environment. Therefore, cables are often used in densely populated and congested areas, playing a very important role in modernization construction.
