Cable is used to transmit electrical (magnetic) energy, information and electrical (magnetic) energy conversion of wire products, it is a wide variety, according to the use of division, there are bare copper wire, power cables, control cables, overhead cables, communication cables, special cables and so on. Different cables are suitable for different industries and working conditions, but looking at these various categories, may everyone be cross-eyed, do not know what they should use? The following article will give you a detailed introduction to different cable applicable industry fields and working conditions.

First, bare copper wire. Bare copper wire, that is, conductive wire without insulation layer and sheath, is mainly used as semi-products of various wire and cable, and a small amount is used for the manufacture of communication wire and motor appliances.

Second, power cable. It is mainly used for the transmission and distribution of electric power cables, often used in urban underground power grids, power station leading lines, industrial and mining enterprises internal power supply and underwater power lines across the river and sea, is a commonly used class of products in industrial procurement.

Three, aerial cable. There are two categories of overhead cable, one is bare wire, no insulation layer, only conductor structure; One is the overhead insulated cable, that is, the overhead wire equipped with an insulating layer and a protective sheath. This kind of cable is basically a line that transmits electrical energy by the conductor set up at a certain height by the pole and tower, which is mainly suitable for the construction of the power grid, and the performance of insulation, corrosion resistance, and external damage is very good.

Four, control cable. This kind of cable structure and power cable is similar, is characterized by only copper core, no aluminum core cable, conductor cross-section is small, the number of cores is more. Suitable for AC rated voltage 450/750V and below, power stations, substations, mines, petrochemical enterprises and other stand-alone control or unit equipment control.

5. Special cables. Special cables are cables with special functions, such as flame retardant, low smoke halogen free, fire resistant, water resistant, anti-corrosion, explosion-proof, rat-proof and termite-proof, etc., which can work normally in harsh environments such as salt and alkali humidity, sun and rain, and high temperature.

For example, flame-retardant cables can prevent the spread of flame, make the cable less likely to burn in the event of an electrical fire, reduce the spread of the flame in the case of continuous burning, and extinguish it naturally after leaving the fire source. When the low-smoke halogen-free cable is burned, the smoke amount is small, and the harmful gas (halogen) in the smoke is also small. These two cables are suitable for important power and control systems, and are widely used in petrochemical, electric power, metallurgy, high-rise buildings and densely populated places.

There is also a fire-resistant cable, in the case of flame burning can maintain a certain time of safe operation, to maintain the integrity of the line, more used in high-rise buildings, underground railways, underground streets, large power stations and important industrial and mining enterprises and other related fields of fire safety and fire rescue.

6. Communication cables. Communication cable is the transmission of telephone, telegraph, fax documents, TV and radio programs, data and other electrical signals of the cable, according to the application, long-distance cable, city cable, office cable, overhead, direct buried, pipeline, underwater and other working environment can be used.

The above are the characteristics and performance of different cables and their applicable industry fields and conditions. Of course, cable products are far more than these listed, with the increasing complexity of demand and use of the environment, cable is also constantly derived from different products to meet different needs, to cope with different environments. We should also combine different needs and situations when choosing, and should not make hasty decisions.
