China's wire and cable industry is the country with the largest production volume in the world, but most of the surplus capacity is low-end products. The concentration of the manufacturing industry is often low, and the market has been in a state of melee. It is no exaggeration to say that we can review the situation. Congestion "cut throat" competition is everywhere, rather than a market share in which an enterprise can be regarded as a real mentor This is an indisputable reality in terms of amount, profit, brand influence and international competitiveness.
With the continuous and rapid growth of China's economy, it provides a huge market space for cable products. The strong temptation of the Chinese market makes the world focus on the Chinese market. In the short decades of reform and opening up, the huge production capacity of China's cable manufacturing industry has made the world look at it with new eyes. With the rapid development of China's wire and cable industry, the number of new enterprises is rising, the overall technical level of the industry has been greatly improved, and a large number of foreign capital has been attracted to China. The wire and cable industry has a wide range of products and applications, involving electric power, construction, communication, manufacturing and other industries, which are closely related to all sectors of the national economy. This article by cable recruitment network finishing release! Cable recruitment network focuses on the wire and cable industry recruitment website! Wire and cable is also known as the "artery" and "nerve" of the national economy. It is an indispensable basic equipment for the transmission of electric energy, the transmission of information, the manufacture of various motors, instruments and meters, and the realization of electromagnetic energy conversion. It is also a necessary basic product in the future electrification and information society. Especially in the fast developing countries like China, the huge demand for infrastructure and supporting facilities construction is self-evident.
As one of the key parts of infrastructure construction, wire and cable industry has a wide range of applications. Including power system: the wire and cable products used in power system mainly include overhead bare wire, bus bar (bus bar), power cable (plastic cable, oil paper power cable (basically replaced by plastic power cable), rubber sheathed cable, overhead insulated cable), branch cable (replacing part of bus bar), electromagnetic wire and electric equipment wire and cable for power equipment, etc; Information transmission system: wires and cables used for information transmission system mainly include local telephone cable, television cable, electronic cable, radio frequency cable, optical fiber cable, data cable, electromagnetic wire, power communication or other composite cables, etc; Mechanical equipment, instrumentation system: except for overhead bare wires, almost all other products have applications, but mainly power cables, electromagnetic wires, data cables, instrumentation cables, etc. Flame retardant wires and cables can be divided into general flame retardant wires and cables, low smoke and low halogen flame retardant wires and cables and low smoke and non halogen flame retardant wires and cables. At present, the main products of flame retardant wire and cable in our country are halogen-containing flame retardant. This kind of wire and cable releases a lot of smoke and corrosive halides when burning, causing casualties and corrosion of various equipment, which is the so-called "secondary disaster". In order to achieve the goal of low smoke, low toxicity and flame retardant, many manufacturers at home and abroad are committed to the development of low smoke, low halogen and low smoke halogen-free flame retardant materials. This kind of material produces less smoke and releases less toxic gas when burning, which reduces the harm to human body and equipment. The research on low smoke, low halogen and low smoke halogen-free flame retardant wire and cable materials in developed countries is relatively early, and the technology is relatively mature, and now it has entered the practical stage. The research and development of low smoke and low halogen, especially low smoke and halogen-free flame retardant wire and cable materials in China is relatively late. At present, the research of low smoke and halogen-free flame retardant wire and cable materials in China is still in the initial stage. Some manufacturers have produced low smoke and halogen-free flame retardant wire and cable materials, but most of them have poor mechanical properties and processing properties. At present, China's low smoke halogen-free flame retardant wire and cable materials mainly rely on imports, the price is expensive, and the application is limited. With the rapid development of China's economic construction and the improvement of safety performance requirements, the demand for low smoke and halogen-free flame retardant wire and cable is increasing. Many domestic manufacturers have increased efforts to develop low smoke and halogen-free flame retardant wire and cable materials. In 2002, the Ministry of Public Security issued the mandatory standard ga306-2001 "flame retardant and fire-resistant cables: classification and requirements for flame retardant and fire-resistant cables with plastic insulation", which classified the fire-resistant cables, specified the smoke emission and smoke toxicity of fire-resistant cables, and further improved the standard system of flame retardant and fire-resistant cables in China, It will promote the popularization and application of flame-retardant, high-efficiency and pollution-free flame-retardant and fire-resistant cables. Low smoke halogen-free flame retardant Shanghai wire and cable material is the key development direction of flame retardant wire and cable in the future. At present, the main products of flame retardant wire and cable in our country are halogen-containing flame retardant. This kind of wire and cable releases a lot of smoke and corrosive halides when burning, causing casualties and corrosion of various equipment, which is the so-called "secondary disaster". In order to achieve the goal of low smoke, low toxicity and flame retardant, many manufacturers at home and abroad are committed to the development of low smoke halogen-free, low smoke halogen-free flame retardant materials.

Focus on wires and cables for modern transportation
In order to cope with the economic crisis and expand domestic demand, the Chinese government has invested heavily in infrastructure construction. Among them, high-speed railway, urban rail transit, modern automobile, ship and large aircraft are the key development projects in China in the future. The manufacture of these modern means of transportation needs a lot of power, control, signal and instrument cables, such as lines for locomotives and rolling stock, signal shielded cables for locomotives and rolling stock, cables for computers and electrical instruments, DC power cables for urban rail transit, low-voltage wires for automobiles, halogen-free and low smoke flame retardant cables for aircraft and ships, etc.
Growing demand for submarine cables
With the increasing tension of global oil and natural gas energy, large-scale offshore oil and natural gas engineering projects have begun to shift from land exploitation to offshore field. The scale of offshore oil and natural gas engineering projects is constantly expanding. It is necessary to transfer power and communication from land to offshore oil platform, and feedback and control of technical data between platforms, so that the demand for integrated submarine cables is growing. According to China's oil development plan, China's offshore oil development will usher in a period of rapid development, and 120 billion yuan will be invested in offshore oil development in the next five years. It is estimated that the growth rate of oil platforms will remain at 8% ~ 10% from 2010 to 2020. The number of oil platforms in China was about 250 in 2008, and each existing oil platform needs about 10km submarine integrated cable for maintenance every year. Each new oil platform needs about 40 km of submarine integrated cables. In addition to the large number of submarine integrated cables used for oil platforms, the demand for submarine integrated cables for the development and utilization of islands in China is also increasing. Combined with the demand for submarine integrated cables for wind power projects in Shanghai, it is estimated that the annual demand for submarine integrated cables for island development and offshore wind power generation is about 300 km.
Special wires in short supply
Special conductor procurement has the characteristics of large single order and tight delivery time. The procurement volume of a large project can reach tens of thousands of tons. At present, the production capacity of domestic special wire manufacturers is relatively small. Taking aluminum alloy wire as an example, the main production enterprises are Qingdao Hanxian, Shanghai Zhongtian aluminum wire, Wuhan cable Co., Ltd. and Hangzhou Zhongce cable. The annual production capacity of each enterprise is only about 5000-10000 tons. The supply period can not meet the engineering requirements, so many projects have to switch to ordinary wires or imported wires .
There is a big gap between supply and demand of cables on oil platforms
The demand quantity of cables for oil platforms is directly related to the construction quantity of oil platforms. The cable consumption for each offshore oil platform is 150km for jack up platform, 180km for semi submersible platform, 200km for oil production platform, 200km for production platform and 100km for living platform. In 2008, China will need 10000 km of cables for new construction and maintenance of offshore oil platforms, and in 2009, it will reach nearly 16000 km. It is expected to exceed 25000 km by 2020.
The application of environmental protection cable has become an international trend
Beijing, Shanghai and other key cities in China have clearly stipulated that PVC wires and cables are prohibited in important buildings, so as to avoid a large amount of smoke and chlorine gas in case of fire, causing more casualties. The use of halogen-free low smoke cross-linked polyolefin insulated wires and cables has become the local regulations in these areas. With the increase of environmental awareness, the application of such wires will gradually expand. With the RoHS directive issued by the European Union, the research and development and large-scale adoption of eco-friendly wires and cables have become an international trend. At present, the application of flame retardant and fireproof cables at home and abroad has been expanded to many fields, such as mining, general rubber sheathed cables, elevator cables and cables for household appliances.
What is the future development trend of wire and cable industry
Wire and cable industry is an important supporting industry for China's economic construction, which is widely used in various fields of the national economy. Wire and cable are indispensable basic equipment for the transmission of electric energy, transmission of information and manufacturing of various motors, electrical appliances, instruments, automobiles, machine tools and other equipment. Wire and cable provide infrastructure for the power industry and communication industry, accounting for a quarter of China's electrical industry The output value of machinery industry is the second largest industry after the automobile industry, which occupies an important position in the national economy. In recent years, China's sustained and rapid economic development, the advancement of urbanization, the construction of large power stations, West to East power transmission, power grid transformation and other major projects all indicate that the wire and cable industry has a long business cycle, so the wire and cable industry will also maintain a high growth rate. China's cable market demand will continue to grow. First, with the rapid development of new energy industry, wind power, nuclear power and other clean energy usher in an unprecedented construction cycle. The market scale of special cables in China is 40-50 billion yuan per year, accounting for 20% - 30% of the total scale of domestic cable market. At present, almost all the high-grade cables needed by China depend on imports; The second is that the copper core twisted pair cable used in communication will still be the leading role of broadband subscriber line in the next 10 years. It is expected that the sales of telephone cable will be for the second time in a few years. The annual sales volume is likely to return to 70-80 million km, showing a steady upward trend; Third, although the domestic market of electronic wire is oversupplied macroscopically, it can not meet the needs of the color TV industry in terms of varieties, specifications and special properties; fourth, 25% of the total output value of power cables, with an annual output value of nearly 40 billion yuan, is a large market, and the market capacity of power cables is still growing at an annual growth rate of 8% - 9%. With the rapid development of China's economy, the demand for special wires and cables with unique performance and special structure for various special places is increasing day by day. Compared with ordinary wires and cables, they have the characteristics of high technology content, strict application conditions, small batch size and high added value. The technical requirements are: flame retardant, halogen-free, no toxic and corrosive gas, no corrosion Heavy metals such as lead, easy to recycle, etc., are widely used in new energy power generation, electrified railway and urban rail transit, ship and offshore oil exploitation, mineral development, high-rise buildings, important military facilities, etc. at present, more than 80% of the domestic cables need to be imported, and the production technology level of our country is low, especially some high-end special cables, the domestic production capacity is low In recent years, the import growth rate of China's special cables is more than 20%. With the continuous improvement of China's special cable manufacturing capacity, there is a trend of import substitution. The application of special cable industry is very extensive, especially with the development of new technology, there will be a wide range of application fields, so the special cable industry has a broad prospect.
