The applications of wires and cables are mainly divided into three categories
Power system used in wire and cable products mainly include overhead bare wires, bus (bus), power cable, power cable (plastic cable, the paper (basic) they were replaced by plastic power cables, rubber sets of cables, overhead insulated cables), branch cable to partly replace bus (), electromagnetic wire, and power equipment with electrical wire and cable equipment, etc.
2. Information transmission system
Wire and cable used in information transmission system mainly include local telephone cable, TV cable, electronic cable, radio frequency cable, optical fiber cable, data cable, electromagnetic cable, power communication or other composite cables.
3. Mechanical equipment, instrument and meter system
In addition to the bare overhead wires, this part of almost all other products are used, but mainly power cables, electromagnetic cables, data cables, instrument and meter cables, etc.
Wire and cable products are mainly divided into five categories
1.Bare wires and bare conductor products
The main characteristics of this product are: pure conductor metal, no insulation and sheath layer, such as steel core aluminum strand, copper aluminum busbar, electric locomotive line, etc.;Processing technology is mainly pressure processing, such as melting, calendering, drawing, stranding/tight stranding, etc.Products are mainly used in the suburbs, rural areas, user mainline, switchgear, etc.
2. Power cables
The main features of this product are: extruding (winding) the insulation layer outside the conductor, such as overhead insulated cable, or several core stranding (corresponding to the phase line, zero line and ground line of the power system), such as more than two core overhead insulated cable, or adding a sheath layer, such as plastic/rubber sheath wire and cable.The main technology includes drawing, stranding, insulation extrusion (wrapping), cable forming, armor, sheath extrusion, etc. There are certain differences in different process combinations of various products.
The products are mainly used in power transmission, distribution, transmission, transformation, power supply lines in the strong electric energy transmission, through the current (dozens of Amperes to thousands of Amperes), high voltage (220V to 500KV and above).
3. Wire and cable for electrical equipment
Such products, the main characteristics are: various specifications, application range, use voltage in 1 kv and below is more, to derive new products constantly, in the face of special occasions, such as fireproof cables, flame retardant cable, low smoke zero halogen/against termites, low smoke low halogen cable, mouse cable, oil/cold/heat resistance, abrasion resistance cable, medical/farm/mining cable, thin wire, etc.
4. Communication cables and optical fibers (brief introduction)
With the rapid development of communication industry in the past 20 years, products also have an amazing speed of development.From the simple telephone and telegraph cables in the past 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 precision is high.
5, electromagnetic wire (winding wire)(the company does not produce such products, so a brief introduction)
Mainly used in all kinds of motors, instruments and meters.
Derivation of wire and cable/new products
Derivative/new products of wire and cable are mainly produced by using new materials, special materials, changing product structure, or improving process requirements, or combining different varieties of products due to different application occasions, application requirements and convenience of equipment and reducing equipment costs.
Different materials such as flame retardant cable, low smoke and halogen free/low smoke and halogen cable, termite proof cable, mouse proof cable, oil resistant/cold resistant/temperature resistant cable, etc.
Change product structure such as: fire-resistant cable, etc.;
Improve process requirements such as: medical cable, etc.;
Combination products such as: OPGW, etc.
Easy to install and reduce equipment cost such as: prefabricated branch cable, etc
