Under normal circumstances, we will be unified wire and cable called wire and cable. "Wire and cable" means materials used for power, electrical and related transmission purposes.

There is no strict boundary and precise and fixed conceptual distinction between "wire" and "cable", which is generally only distinguished by daily experience. Generally, the products with a small number of cores, small product diameter and simple structure are called wires, those without insulation are called bare wires, and others are called cables. The cross-sectional area of the conductor is greater than 6 square millimeters, which is called a large cable, and the cross-sectional area of the conductor is less than or equal to 6 square millimeters, which is called a small wire, also known as a cloth wire.

Wires are generally used to carry current conducting metal wires, solid, stranded or foil braided in various forms. According to the insulation condition is divided into bare wire and insulated wire two categories.

A cable is an insulated wire consisting of one or more mutually insulated conductive wire cores placed in a sealed sheath. It can be covered with a protective layer for the transmission, distribution of electrical energy or transmission of electrical signals. The difference between it and ordinary wires is mainly that the cable size is larger and the structure is more complex.

The difference between wire and cable

The difference between wire and cable is that the size of the wire is generally small and the structure is relatively simple, but sometimes the cable is classified as a generalized wire. In a narrow sense, it is divided into wires and cables, and in a broad sense, it is generally referred to as cable. So what's the difference between wire and cable?

The broad sense of wire and cable is also referred to as the cable, the narrow sense of cable refers to the insulated cable, it can be defined as: composed of the following parts of the aggregate; One or more insulated wire cores, and the cladding, total protective layer and outer protective layer they may each have, and the cable may have additional uninsulated conductors. Wire products used to transmit electrical (magnetic) energy, information and achieve electromagnetic energy conversion. Simply put, the wire is composed of one or several soft wires with a light and soft protective layer. A cable consists of one or more insulated conductors wrapped in a tough outer layer of metal or rubber.

Cables and wires are generally composed of three components: core wire, insulating sheath and protective sheath. Each conductor of a cable counts as a strand of wire. This is a straightforward difference between wire and cable.

1, the difference of materials

A conductive metal wire used to carry current. Available in various forms, such as solid, twisted or foil woven. According to the insulation condition is divided into bare wire and insulated wire two categories. A cable is an insulated wire consisting of one or more electrically conductive wires with mutually insulated cores placed in a sealed sheath. The difference between the wire and the cable is that the size of the wire is generally small and the structure is relatively simple, but sometimes the cable is classified as a generalized wire.

2. Difference in structure

The difference between power cables and ordinary wires is mainly that the cable size is larger and the structure is more complex.

The cable mainly consists of the following four parts.

Conductive core: made of high conductivity material.

Insulation layer: The insulating material used for cables should have high insulation resistance and high breakdown electric field strength. Cables are often classified as insulating materials.

3, the difference in use

Bare wire A wire not covered with any insulation or protective coating. In addition to the transmission of electrical energy and information wire, can also be used to manufacture motor, electrical components and connections. Generally used copper, aluminum, copper alloy, aluminum alloy.

In addition, there are a variety of insulated wires suitable for special requirements, such as low-voltage wires for automobiles, high-voltage ignition wires for automobiles, motor electrical wiring, aviation wires, compensation wires, etc.

Cables are used to transmit, distribute, or transmit electrical signals.

Cables can be divided into power cables, communication cables and control cables according to their use.

In addition to the above differences, cables also have obvious advantages. Compared with the overhead line, the advantages of the cable are that the insulation distance between the lines is small, the floor space is small, the underground laying does not occupy the space above the ground, is not affected by the surrounding environmental pollution, the power transmission reliability is high, and the interference to personal safety and the surrounding environment is small.

Therefore, the cable is mainly used in densely populated and grid dense areas and traffic congestion. It plays an important role in modernization.

Qingdao Tianxing Cable Co., Ltd. focuses on the production of customized wire and cable manufacturers, main: fire wire and cable, power cable, control cable and other products, exported to more than 40 countries and regions around the world, the annual production capacity of 1 billion yuan. 6000 square meters of storage, standing hundreds of millions of inventory, order demand for rapid distribution and delivery, large prices more favorable.
