What is the cable wire device?
  Wire and cable equipment for transmitting electrical (magnetic) energy, information and achieve electromagnetic energy conversion wire products. Generalized wire and cable also referred to as cable. Cable narrowly refers insulated cables. It can be defined as: assembly consists of the following components: one or more insulated core and cladding layers may have their respective total protection layer and the outer sheath. There is also no additional cables insulated conductors.
  For transmitting electric (magnetic) energy, information and achieve electromagnetic energy conversion wire products. Generalized wire and cable also referred to as cable. Cable narrowly refers insulated cables. It can be defined as: assembly consists of the following components: one or more insulated core and cladding layers may have their respective total protection layer and the outer sheath. There is also no additional cables insulated conductors.
Classification
  1, bare wires and bare conductor products main features of the products are: pure conductive metal, without insulation and sheathing layer, such as ACSR, copper and aluminum busbars, electric locomotive line wire and cable; processing main pressure processing, such as smelting, rolling, drawing, stranding / pressed stranded; products are mainly used in suburban, rural, user mainline, switch cabinets.
  2, the main feature of the power cable products are: conductor outside crowded (around) package insulating layer, such as overhead insulated cables, or a few stranded (corresponding to the power system phase line, neutral and ground), such as two-core above overhead insulated cables, or additional coating layer, such as plastic / rubber wire and cable. The main technology has drawn, stranded, insulated extrusion (wrapped), a cable, armored, protective layer extrusion, a combination of different processes of various products have some differences. Products are mainly used in the hair and distribution, transmission, transformation, supply lines strong electric power transmission, the current through the large (tens of thousands of security to security), high voltage (220V to 35kV and above).
  3, electrical wire and cable equipment such products main features are: many varieties and specifications, wide range of applications, the use of voltage 1kV and below in more face special occasions continue to rise to new products, such as fire-resistant cables, fire-retardant cable LSZH / LSF cable, termite, anti-mouse cable, oil / cold / temperature / wear cable, medical / agricultural / mining cables, wires and other thin-walled.
  4, communication cables and fiber optic wire and cable with the rapid development of the communications industry, from the past simple phone development to thousands of telegraph cables, then cable, coaxial cable, fiber optic cable, data cable, or even a combination of cable and other communications. Such products are usually small and uniform structure size, high precision manufacturing.
  5, magnet wire (winding wire) is mainly used for a variety of electrical, instrumentation and so on.
  6. Wire and Cable derivative / New Products Wire and Cable derivative / new product is mainly due to the requirements of convenience and lower equipment costs and other applications, different applications and equipment, and the use of new materials, special materials, or changes in product mix or improve process requirements, or a combination of different varieties of products and production. Using different materials such as flame-retardant cable, halogen / LSF cable, termite, anti-mouse cable, oil / cold / temperature cables, etc.; changes in product mix, such as: fire-resistant cables; improve the process Requirements such as: medical cables and the like; combinations of products such as: OPGW, etc; easy installation and reduce equipment costs such as: prefabricated branch cables.
Industry
    Wire and cable equipment industry has only a supporting industry, but occupy a quarter of the output value of China electrical equipment industry. It is many types of products, wide range of applications, involving electricity, construction, communications, manufacturing and other industries, are closely related to each sector of the national economy. Wire and cable is also known as an economic "arteries" and "nervous", is supplying electric power, transmission of information and manufacturing all kinds of motors, instruments, meters, electromagnetic energy conversion to achieve indispensable basic equipment is the future electrification, information Society in the necessary basic products. China wire and cable industry is second only to the automotive industry the second largest industry, product variety to meet the rate and the domestic market share of more than 90%. Worldwide, total output value of China's wire and cable has surpassed the United States as the world's largest wire and cable producer. Along with the rapid development of China's wire and cable industry, the rising number of new enterprises, the industry overall technical level has been greatly improved. 2007 January to November, China's wire and cable manufacturing industry realized a total industrial output value of 476,742,526 yuan, an increase of 34.64% over the previous year; to achieve total sales revenue 457,503,436 yuan, an increase of 33.70% over the previous year; to achieve total total profit of 18,808,301 thousand dollars, over the previous year an increase of 32.31%.
  2008 January to May, China's wire and cable manufacturing industry realized a total industrial output value of 241,435,450,000 yuan, an increase of 26.47% over the previous year; to achieve total sales revenue 227,131,384,000 yuan, an increase of 26.26% over the previous year; to achieve total profit 8,519,637,000 yuan, an increase of 26.55 percent over the same period last year. China's sustained and rapid economic growth, the cable products provide a huge market space, the strong Chinese market allure, make the world all eyes are focused on the Chinese market, in just a few decades of reform and opening up, Chinese cable manufacturing It formed a huge production capacity to make the world sit up. With the continuous expansion of China's power industry, data communication industry, urban rail transportation, automotive industry and shipbuilding industries of scale, the demand for wire and cable also will grow rapidly in the future there is huge potential for development of wire and cable industry.
