Wire and cable product classification
Date: 2022.08.26 Viewed:

The application of wire and cable is mainly divided into three categories:

1. The wire and cable products used in the power system mainly include overhead bare wires, bus bars (bus bars), power cables (plastic cables, oil-paper power cables (basically replaced by plastic power cables), rubber sheathed cables, overhead insulated cables ), branch cables (replacing part of the busbars), electromagnetic wires and electrical equipment wires and cables for power equipment, etc.

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 This part is used for almost all other products except overhead bare wires, but mainly power cables, electromagnetic wires, data cables, instrumentation cables, etc.

Wire and cable products are mainly divided into five categories:

1. Bare wire and bare conductor products The main features of this type of product are: pure conductor metal, no insulation and sheath layer, such as steel-cored aluminum stranded wire, copper-aluminum busbar, electric locomotive wire, etc.; the processing technology is mainly pressure Processing, such as smelting, calendering, drawing, stranding/compression stranding, etc.; the products are mainly used in suburban, rural areas, user main lines, switch cabinets, etc.

2. The main features of this type of power cable are: extruding (winding) an insulating layer outside the conductor, such as an overhead insulated cable, or twisting several cores (corresponding to the phase wire, neutral wire and ground wire of the power system), such as two cores Above overhead insulated cables, or add a jacket layer, such as 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 power generation, distribution, transmission, transformation and power supply lines, with large currents (tens of amps to thousands of amps) and high voltages (220V to 500kV and above).

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

4. Communication cables and optical fibers (the company does not produce such products at present, so I will make a brief introduction) With the rapid development of the communication industry in the past two decades, the products also have an amazing development 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.

5. Electromagnetic wire (winding wire) (the company does not produce such products at present, so it is briefly introduced) It is mainly used in various motors, instruments and meters. Derivatives/new products of wires and cables: Derivatives/new products of wires and cables are mainly due to the requirements of application occasions, application requirements, convenience of equipment and reduction of equipment costs, etc., and adopt new materials, special materials, or change product structure. Different materials such as flame-retardant cables, low-smoke halogen-free/low-smoke and low-halogen cables, termite-proof, mouse-proof cables, oil-resistant/cold-resistant/temperature-resistant cables, etc.; change product structure, such as fire-resistant cables, etc.; improve process requirements Such as: medical cables, etc.; combination products such as: OPGW, etc.; easy to install and reduce equipment costs, such as prefabricated branch cables, etc.
