The five major classifications of wires and cables, which five categories of wires and cables are di

Bare wire body products.

The main characteristics of this type of products are: pure conductor metal, no insulation and sheath layer, such as steel core aluminum stranded wire, copper-aluminum busbar, electric locomotive line, etc.; The processing technology is mainly pressure processing, such as smelting, calendering, drawing, stranding, pressing and stranding, etc.; The products are mainly used in suburbs, rural areas, user mainlines, switch cabinets, etc.

Power cables. The main characteristics of this type of product are: extruding (winding) the insulating layer outside the conductor, such as overhead insulated cables, or several cores stranded (corresponding to the phase wire, neutral wire and ground wire of the power system), such as overhead insulated cables with more than two cores, or adding a sheath layer, such as plastic rubber sheathed wires and cables.

The main process technologies are drawing, stranding, insulation extrusion (wrapping), cable formation, armor and sheath extrusion, etc., and the different process combinations of various products are different.

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 current (tens of amperes to thousands of amperes) and high voltage (220V to 35kV and above).

Wires and cables for electrical equipment.

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

Communication cables and optical fibers.

With the rapid development of the communication industry, it has developed from simple telegraph cables in the past to thousands of pairs of telephone cables, coaxial cables, optical cables, data cables, and even combined communication cables. The structural size of this type of product is usually small and uniform, and the manufacturing accuracy is high.

Winding wires. A winding wire is a conductive metal wire with an insulating layer that is used to wind the coils or windings of electrical products. When it acts, a magnetic field is generated by an electric current, or a magnetic field line is cut to generate an induced current, and the conversion of electrical energy and magnetic energy is realized, so it becomes a magnet wire.

The five major classifications of wires and cables, I'm sorry, I can't give you this question, I don't know much about this thing, you still ask the professional and technical personnel!

1. Bare wires. Bare wire refers to the electric hand wire without insulation, this kind of wire can be used as a conductive wire, can also be used as electrical appliances and other equipment components, etc., its conductivity, mechanical properties are superior, but because it has no insulation layer, it is easy to be corroded. Liquid closed.

2. Power cables. As the name suggests, power cable products are mainly used to transmit and distribute electric energy, and have the advantages of not occupying ground space, stable transmission of western energy, and large distributed capacitance. If it is divided according to the insulating material, it can range from oil-impregnated paper, plastic, and rubber insulated power cables; If it is divided according to voltage, it can be divided into low voltage, medium and low voltage, high voltage, ultra-high voltage, and ultra-high voltage cables.

3. Wires and cables for electrical equipment. The wire and cable used in electrical equipment is the most widely used, and the wire used in the power supply connected to the electrical equipment is this type, which has a wide variety, low rated voltage, and various functions of insulation materials, and different types of electrical equipment wires are different and universal, with strong professionalism.

4. Communication cables. Communication cable is a wire product used to transmit electrical signals such as ** and TV, usually with multiple conductors forming the cable core, and the outer layer is protected by a protective sleeve. This kind of wire has the advantages of good confidentiality, less external interference, large communication capacity, and difficult maintenance.

5. Magnet wire. Magnet wire is mainly used to make coils in motors, electrical appliances and other products, and its product performance should meet the requirements of electrical appliances and other uses and processes. Electromagnetic buried wire can be divided into various types such as enameled wire and wrapped wire.

According to the use, it can be divided into bare wires, insulated wires, heat-resistant wires, shielded wires, power cables, control cables, communication cables, radio frequency cables, etc.;

Common insulated wires are as follows: PVC insulated wires, PVC insulated wires, nitrile PVC mixture insulated wires, rubber insulated wires, agricultural underground directly buried aluminum core plastic insulated wires, rubber insulated cotton yarn textile wires, PVC insulated nylon sheathed wires, PVC insulated soft wires for electricity and lighting, etc.;

The cable tray is suitable for indoor and outdoor overhead laying of power cables and control cables in general industrial and mining enterprises, and can also be used for indoor and outdoor erection in telecommunications, radio and television departments;

Commonly used electrical accessories include cable terminal junction boxes, cable middle junction boxes, connecting pipes and terminals, steel plate wiring ducts, cable trays, etc.;

The device that connects the cable with the conductor, insulating shield and protective layer of the cable to connect the cable route is called the cable intermediate joint.
