Wires and electrical cables are essential building materials for house decoration. In modern homes, wires and cables are the most common current conductors in the family. Many people are confused about the difference between wires and cables. Both are composed of wires, but their structures are different.
The first difference between wires and electrical cables
The first difference between wires and electrical cables is that wires can be used to transmit electrical energy. They can also be used as components and connecting wires for the manufacture of motors and electrical appliances. They are generally made of copper, aluminum, etc.; while electrical cables are mainly used for communication and electricity, so cables are also divided into communication cables, power cables, control cables, etc. Cables are generally not used for the manufacture of motors, but for large-span overhead lines.
The second difference between wires and electrical cables
The wire is a conductive metal wire used to carry current. It has a variety of forms such as solid, stranded, and foil. The size of the wire is small and the structure is simple; while the cable is composed of one or more mutually insulated conductive cores, which formed in the hermetic sheath. The size of the cable is larger and the structure is more complicated.
Apart from the differences, let’s take a look at the standards of wires and electrical cables. The production of wires and cables needs to meet national standards, otherwise, there will be safety hazards. The production standard of the wire is that it must reach the specified load voltage to ensure safety. In addition, the wire should also have good electrical conductivity, mechanical properties, and thermal properties. The material of the wire must also have corrosion resistance and weather resistance, so as to ensure the service life of the wire; the standards of cables and wires are similar, the main emphasis is on safety issues, which are related to the use of raw materials and the continuity of production standard. Besides, wires and cables have relevant standards for the use of raw materials and the continuity of production.
