Wire and cable knowledge sharing: the classification of wire and cable

Wire and cable are terms often used in the field of electrical and communications.

A wire is measured by its diameter. Depending on the diameter of the wire, a gauge number is used to measure it. The smaller the gauge number, the thicker the wire. The perfect gauges used in residential applications are 10 and 20. However, keep in mind that larger wires carry more current and can damage household appliances by blowing fuses.

The cable contains a hot wire to carry the current, a neutral wire to complete the loop, and a ground wire. Cables are classified by the total number of wires they consist of and their specifications.

The classification of wire and cable

Wire and cable products are divided into five main categories.

1. Bare wire and bare conductor products

The main characteristics of this category are: pure conductor metal, no insulation and sheath layer, such as steel stranded aluminum strand, copper and aluminum busbar, electric locomotive lines, etc.; processing technology to pressure processing, such as melting, calendering, wire drawing, stranding/compression stranding, etc.; products are mainly used in suburban areas, rural areas, user trunk lines, switchgear, etc.

2. Power cord

The main characteristics of this type of product are: insulation layer extrusion (winding) outside the conductor, such as overhead insulated cables, or multi-core stranding (corresponding to the phase, neutral, ground of the power system), such as more than two cores or additional sheath layer of overhead insulated cables, such as plastic/rubber wire and cable. The leading process technologies are wire drawing, stranding, insulation extrusion (package), cable formation, armoring, sheath extrusion, etc. There are specific differences in different process combinations for various products.

Products are mainly used in power generation, distribution, transmission, substation, and power supply lines in the transmission of electricity, through the current (tens of a to thousands of a), high voltage (220V to 500kV and above).

3. Electrical equipment with wire and cable

The main characteristics of this category are many specifications and a wide range of applications, primarily using 1kV and the following voltage. In the face of special occasions, the continuous derivation of new products, such as fire-resistant cables, flame retardant cables, low-smoke halogen-free / low-smoke low-halogen cables, termite resistant, rodent-proof cables, oil/cold/temperature / wear-resistant cables, medical/agricultural/mining cables, thin-walled wires, etc.

4. Communication cables and optical fiber

In the past 20 years, with the rapid development of the communications industry, the product also has had a fantastic rate of development, from the past simple telephone and telegraph cables to thousands of pairs of voice cables, coaxial cables, optical cables, data cables, and even combined communication cables.

These products are usually smaller and uniform in structure size and manufacturing precision.

5. Electromagnetic wire (winding wire)

They are mainly used in various motors, instruments, and meters.

Wire and cable derivatives/new products.

Wire and cable derivatives/new products are mainly due to different applications, application requirements, equipment convenience, reduced requirements, the use of new materials, unique materials, changes in the product structure, improved process requirements, or a combination of different varieties of products. Equipment cost.

We are adopting different materials for wires and cables, such as flame retardant cables, low-smoke halogen-free/low-smoke halogen-free cables, termite resistant cables, rodent resistant cables, oil/cold/temperature resistant cables, etc.

Change the product structure of wire and cable, such as fire-resistant cables, etc.

We are improving the process requirements of wire and cable, such as medical cables, etc.

With the development of technology and the improvement of people's living standards, whether in the field of industrial technology or daily life, office, people's functional and quality requirements for wire and cable are increasingly high, so wire and cable have been developing in the direction of diversity, to meet the production needs of a variety of different types of wire and cable, wire and cable production equipment is also making continuous progress.
