Where are the wires and cables used?

The application of wire and cable can be seen everywhere in our lives, so where will it be applied? What are its main properties and uses?

1. Power system

The wire and cable products used in the power system mainly include overhead bare wires, power cables, oil-paper power cables, rubber sheathed cables, overhead insulated cables, branch cables, magnet wires, and electrical equipment wires and cables for power equipment.

2. Information transmission system

The wires and cables used in the information transmission system mainly include local telephone cables, TV cables, electronic cables, radio frequency cables, optical fiber cables, data cables, electromagnetic wires, power communication or other composite cables.

3. Mechanical equipment, instrumentation system

Except for overhead bare wires, almost all other products are used in this part, but mainly power cables, magnet wires, data cables, instrumentation cables, etc.

Wire and cable products are mainly divided into several categories

1. Bare wires and bare conductor products

The main features of this type of products are: pure conductor metal, without insulation and sheath layers, such as steel-cored aluminum stranded wires, copper-aluminum busbars, electric locomotive wires, etc.; the processing technology is mainly pressure processing, such as smelting, calendering, drawing The products are mainly used in suburban, rural areas, user main lines, switch cabinets, etc.

2. Power cable

The main features of this type of product are: the conductor is covered with an insulating layer, such as an overhead insulated cable, or several cores are twisted, such as an overhead insulated cable with more than two cores, or a sheath layer is added, such as a plastic/rubber sheathed wire and cable. The main process technologies are drawing, stranding, insulation extrusion (wrapping), cabling, armoring, sheath extrusion, etc. There are certain differences in the combination of different processes of various products.
The products are mainly used in the transmission of strong electric energy in the generation, distribution, transmission, transformation and power supply lines, and the current and voltage are large.

3. Wire and cable for electrical equipment

The main features of this type of products are: a wide variety of specifications, a wide range of applications, the use of voltages of 1kV and below, and new products are constantly derived in the face of special occasions, such as fire-resistant cables, flame-retardant cables, low-smoke and low-halogen cables , Anti-termite, anti-rat cables, oil-resistant, cold-resistant, temperature-resistant, wear-resistant cables, medical, agricultural, mining cables, thin-walled wires, etc.

4. Communication cables and optical fibers

With the rapid development of the communication industry in the past two decades, products have also developed at an astonishing speed. From the simple telephone and telegraph cables in the past to thousands of pairs of voice cables, coaxial cables, optical cables, data cables, and even combined communication cables.
The structure size of such products is usually small and uniform, and the manufacturing precision is high.
