Wire and cable products are mainly divided into five categories: bare wires and bare conductors, power cables, wires and cables for electrical equipment, communication cables and optical fibers, and electromagnetic wires (winding wires)
 
1. Bare wires and bare conductor products
The main features of this category of products are: Pure conductive metal, without insulation and sheath, such as steel core aluminum stranded wire, copper-aluminum bus bar, electric locomotive wire, etc.; The processing technology is mainly pressure processing, such as smelting, calendering, drawing, stranding / compaction stranding, etc.; The products are mainly used in suburbs, rural areas, user main lines, switch cabinets, etc.

2. Power cable
The main features of this category of products are:
Extrude (wind) the insulation layer outside the conductor, such as: overhead insulated cable, or stranded several cores (corresponding to the phase wire, neutral wire and ground wire of the power system). For example, overhead insulated cables with more than two cores, or additional sheathing. For example, plastic/rubber sheathed wire and cable. The main process technologies include drawing, stranding, insulation extrusion (wrapping), cabling, armoring, and sheath extrusion. There are certain differences in the combination of different processing procedures for various products.


3. Wires and cables for electrical equipment
The main features of this type of product are: There are many varieties and specifications and a wide range of applications. The operating voltage is mostly 1kV and below, and new products are constantly being introduced in the face of special occasions. Such as fire-resistant cables and flame-retardant cables. Low-smoke and halogen-free, low-smoke and low-halogen cables. Anti-termite, anti-mouse cable, Oil-resistant, cold-resistant, temperature-resistant, abrasion-resistant cables, Medical, agricultural, mining cables, Thin-walled wires, etc.

4. Communication cables and optical fibers (a brief introduction)
With the rapid development of the communications industry in the past two decades, products have also developed at an astonishing speed. From the simple telephone and telegraph cables in the past, it has developed to thousands of pairs of voice cables, coaxial cables, optical cables, data cables, and even combined communication cables.
The structure size of this kind of products is usually small and uniform, and the manufacturing precision is high.

5. Magnet wire (winding wire)
Mainly used in various motors, instruments, etc.


Derivatives/new products of wires and cables are mainly due to different application occasions, different application requirements, convenience of equipment, and requirements for reducing equipment costs. However, it is produced by using new materials, special materials, or changing product structure, or improving process requirements, or combining products of different varieties.
Use different materials such as flame-retardant cables,
Low-smoke and halogen-free/low-smoke and low-halogen cables,
Anti-termite, anti-mouse cable,
Oil/cold-resistant, temperature-resistant cables, etc.;
Change the product structure such as: fire-resistant cable, etc.;
Improve process requirements such as: medical cables, etc.;
Combination products such as OPGW, etc.;
It is convenient to install and reduce equipment costs, such as prefabricated branch cables.

The model composition and sequence of the cable are as follows:
