Everything in the world has its own attributes and levels, cable products are wide variety, widely used. Even if you're in the industry, you don't know everything. Today, this article organized by wire and cable professional manufacturers classifieds wire and cable products, which can help you better understand the meaning of specifications and models.

One, bare copper wire. Bare wire and bare conductor products refer to conductors without insulation and sheath, including bare single wire, bare stranded wire and profiles. Copper single wire includes soft copper single wire, hard copper single wire, soft aluminum single wire and hard aluminum single wire, mainly used as a variety of wire and cable semi-finished products, a small amount of used in the manufacture of communication wires and electrical appliances. Bare wire includes hard copper stranded wire, hard aluminum stranded wire, aluminum alloy stranded wire, steel core aluminum stranded wire, mainly used for the connection of electrical equipment and electronic appliances or components. The specifications of the above twisted cables range from 1.0 to 300mm2.

2. Power cables. Power cable is a professional manufacturer of wire and cable for the transmission and distribution of high power cable products, including 1 ~ 330KV and above all kinds of insulation, all kinds of voltage levels of power cable. The cores are 1, 2, 3, 4, 5, 3+1, 3+2, and the cross sections are 1.5, 2.5, 4, 6, 10, 16, 25, 35, 50, 70, 95, 120, 150, 185, 240, 300, 400, 500, 630, 800mm2. Power cables can be divided into low-voltage cables, medium-voltage cables and high-voltage cables according to voltage levels, and plastic insulated cables, rubber insulated cables and mineral insulated cables according to insulation conditions.

Three, overhead insulated cable. Overhead cables are also common and are characterized by their lack of sheathing. Many people have three misunderstandings about this kind of cable: 1. Its conductor is not only aluminum, but also copper conductor and aluminum alloy. Now there are steel core aluminum gallows air cables. 2, not only a single core, the common is usually a single core, but it can also be several wires twisted into a bundle. 3. The voltage level of the overhead cable is 35KV and below, not 1KV and 10KV.

Four, control cable. The structure of this cable is similar to that of power cable, characterized by only copper core without aluminum core cable, conductor section is smaller, the number of cores is more, suitable for power stations, substations, mines, petrochemical enterprises and other stand-alone control or unit equipment control. Rated AC voltage is 450/750V and below, wire and cable professional manufacturers in order to improve the ability to control signal cables to prevent internal and external interference, mainly use shielding layer.

V. Special cables. Special cables are cables with special functions, including flame-retardant cables, wdz cables, fire-resistant cables, explosion-proof cables, rat-proof cables, termite-proof cables and waterproof cables. Flame-retardant cables, low-smoke halogen-free cables are mainly suitable for important power and control systems. This kind of cable is widely used in petrochemical, electric power, metallurgy, high-rise buildings and densely populated places by professional manufacturers of wire and cable.
