Wire and cable products are mainly classified

Wire and cable products are mainly divided into five categories:

1, bare wire and bare conductor products

The main features of this product are: pure conductor metal, no insulation and jacket layer, such as steel core aluminum stranded wire, copper and aluminum bus, electric locomotive line; The processing technology is mainly pressure processing, such as melting, calendering, drawing, stranding/compression stranding, etc.; Products are mainly used in the suburbs, rural areas, user main line, switchgear and so on.

2. Power cable

The main features of this product are: extruded (wound) insulation layer outside the conductor, such as overhead insulated cable, or a few cores stranded (corresponding to the phase line, neutral line and ground line of the power system), such as more than two core overhead insulated cable, or add a sheath layer, such as plastic/rubber sheath wire and cable. The main process technologies are drawing, stranding, insulation extrusion (wrapping), cable forming, armor, sheath extrusion, etc. There are certain differences in different process combinations of various products.

Products are mainly used in power transmission, distribution, transmission, transformer, power supply lines in the strong electric energy transmission, through the current (tens of amps to thousands of amps), high voltage (220V to 500kV and above).

3, electrical equipment with wire and cable

The main characteristics of this kind 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 constantly derived new products, such as refractory cables, flame retardant cables, low smoke halogen free/low smoke halogen cables, termite-proof, anti-mouse cables, oil/cold/temperature/wear resistant cables, medical/agricultural/mining cables, thin wall wires.

4, communication cable and optical fiber (the company does not produce such products at present, pretend to be a brief introduction)

With the rapid development of the communication industry in the past 20 years, products have also developed at an amazing speed. From the past simple telephone and telegraph cables have developed to thousands of pairs of cable, coaxial cable, optical cable, data cable, and even combined communication cables.

The structure size of this kind of product is usually small and uniform, and the manufacturing accuracy is high.

5, electromagnetic wire (winding wire)(the company does not currently produce such products, pretend to be a brief introduction)

Mainly used for all kinds of motors, instruments and meters.

Derivative/new products of wire and cable:

The derivative/new products of wire and cable are mainly due to the requirements of different application occasions, different application requirements and the convenience of equipment and reducing the cost of equipment, etc., and the use of new materials, special materials, or change the product structure ⒒蛱 goulacひ

Different materials are used, such as flame retardant cables, low smoke halogen free/low smoke and low halogen cables, termite-proof, rat-proof cables, oil/cold/temperature resistant cables, etc.

Change the product structure such as: fire-resistant cable;

Improve process requirements such as: medical cables;

Combined products such as: OPGW, etc.;

Easy to install and reduce equipment costs, such as: prefabricated branch cables
