From the Eleventh Five-Year Plan, China's megacities began to use high-voltage, ultra-high-voltage cable lines deep into the city load center, the Twelfth Five-Year Plan period to 220 kV cross-linked cables as well as a small number of 500 kV cable lines will enter the city center, and the construction of large hydropower plants also need to use part of the 500 kV cable, but so far the domestic 500 kV cables and accessories are provided by foreign countries, although a large number of domestic tower production line (VCV), but still can not complete the manufacture of 500 kV cables and accessories
　　In the China Electrical Appliances Industry Association Wire and Cable Branch (hereinafter referred to as "Cable Branch") made by the "wire and cable industry, the 12th Five-Year Development Plan" (draft for comment), listed the goals of the 12th Five-Year Development of China's cable industry.

　　Three goals
　　First, the industry should maintain steady economic growth and improve the quality and efficiency of development. It is expected that during the 12th Five-Year Plan, the average annual growth of the industry sales scale of about 4% to 8%, by the end of the 12th Five-Year Plan, the forecast copper volume of about 5.5 million to 6.2 million tons, with aluminum volume of about 2.6 million to 3.2 million tons.
　　Secondly, we should strengthen and enlarge the enterprises and optimize the industrial organization structure. Through acquisitions, mergers, unions and other industrial restructuring activities, and strive to the end of the 12th Five-Year Plan in the industry to form 3 to 5 sales of tens of billions of yuan and has a certain international competitiveness of large enterprise groups, the formation of 6 to 12 sales of 10 billion yuan and in the field of professional products with strong international competitiveness of specialized enterprises, the formation of a number of products with their own characteristics, strong professional manufacturing capacity, supporting More complete, differentiated development of regional cable industry clusters, the formation of a number of professional production characteristics as well as regional competitive advantages of small and medium-sized enterprises.
　　Third, the industry should improve the level of technology, improve the proportion of R & D personnel and R & D investment ratio, strengthen the technological innovation capacity of enterprises; advocate the establishment of industrial strategic technology alliances to achieve joint research, and strive to achieve a number of high-end products during the 12th Five-Year Plan period, the industrialization of a number of industry technology bottlenecks and product bottlenecks.
　　Comparison of the eleventh five-year period of China's cable industry development, it can be found that this development plan for the twelfth five-year period of the cable industry sales value growth rate is estimated to be lower than the actual value of the eleventh five-year period. It is understood that the end of the fifteen years in 2005, China's cable industry sales value of 282.959 billion yuan, only in 2009 sales value of 731 billion yuan, 1/3 strong. After the next three years, China's annual sales value of the cable industry have achieved rapid growth, growth value of more than 130 billion yuan, ringgit growth of more than 20%, the growth in 2006 compared to 2005 was a record 47.75% of the amazing figures, and this high growth in the 12th Five-Year Plan period will slow down.
　　With the slowdown in growth, is the cable branch of the cable industry has been the lack of high-end products, low-end market melee, industry concentration is too low, a serious lack of high-quality personnel and other issues of concern, in order to guide the development of the industry, in the planning, it also pointed out some future research projects and new product development projects worthy of attention.

　　Research project proposals
　　In the planning, the cable branch listed a total of nine scientific research projects, including research on the basis of high-voltage cross-linked cable applications, marine engineering series of cables, fiber optic prefabricated rod products, superconducting cables and so on.
　　It is understood that China's high-voltage cross-linked cable insulation is generally thick, and because there is no applied basic research, currently unable to optimize the design parameters, the 12th Five-Year Plan period, the organization of relevant enterprises engaged in this type of cable related to basic research, long-term dynamic research, optimization of design parameters is necessary.
　　From the Eleventh Five-Year Plan, China's megacities began to use high-voltage, ultra-high-voltage cable lines deep into the city load center, the Twelfth Five-Year Plan period to 220 kV cross-linked cables as well as a small number of 500 kV cable lines will enter the city center, and the construction of large hydropower plants also need to use part of the 500 kV cable, but so far the domestic 500 kV cables and accessories are provided by foreign countries, although a large number of domestic vertical tower production line (VCV), but still can not complete the manufacture of 500 kV cables and accessories
　　And China's attention to the development of the sea, but also make the research of the marine engineering series of cables become a must. Offshore engineering cables cover the platform for oil and gas extraction with conventional operating cables, also including subsea oil and gas resources aluminum core exploration cables and other submarine wrecks, treasure hunting, geological and mineral exploration cables, such as oil platforms commonly used cables, including water use cables, submersible use cables, ribbon cables, armored cables, load-bearing cables, integrated fiber optic cables, monitoring cables, etc. It is reported that during the 12th Five-Year Plan period, China's offshore oil and gas development will produce 250 billion to 300 billion yuan of investment in offshore equipment, new, maintenance of offshore oil platforms will also require 7,000 to 10,000 kilometers of various types of cables. But the cable branch also reminded that the development of offshore engineering with a series of cables also have risks, the development of large-scale equipment, large investments, and face the risk of fierce competition with famous foreign manufacturers.
　　Cable Branch recommended the study of fiber optic prefabricated rod products and their manufacturing technology, but entirely due to the production of optical fiber products, including even SiC14, GeC14 and other raw materials is still a significant shortage in China, China's proportion of imports of prefabricated rod up to 80% or more. It is recommended that the state establish projects, focus on funding, focus on supporting 2 to 3 enterprises suitable for batch do conventional optical fiber preform, develop and promote the localization of equipment, especially the relevant supporting equipment research and development, the formation of optical fiber preform manufacturing equipment industry chain, and rapidly improve China's optical fiber preform production capacity. At the same time, it is recommended that the state increase the support of special optical fiber preform, encourage enterprises to target the international high-tech frontier, for special field needs to carry out applied basic research, key technologies and common technology research, to improve the ability of independent innovation.
　　For the United States, Japan and Europe are currently engaged in superconducting cable research, the cable branch recommended that during the 12th Five-Year Plan, China shall engage in low-temperature insulation and high-temperature superconducting cable technology research, to replace the traditional cable in the ultra-high voltage high-capacity transmission system to lay the technical foundation, and should be based on cable manufacturing technology, combined with other professional technology for scientific research and development work.
　　From the Eleventh Five-Year Plan, China's megacities began to use high-voltage, ultra-high-voltage cable lines deep into the city load center, the Twelfth Five-Year Plan period to 220 kV cross-linked cables as well as a small number of 500 kV cable lines will enter the city center, and the construction of large hydropower plants also need to use part of the 500 kV cable, but so far the domestic 500 kV cables and accessories are provided by foreign countries, although there are a large number of domestic vertical tower production line ( VCV), but still can not complete the manufacture of 500 kV cables and accessories, therefore, high-voltage, ultra-high-voltage cross-linked cables and accessories research is included in the scientific research project. Wire and cable branch recommended that the relevant basic theoretical research work should be engaged in the design parameters, elimination of thermal stress, process requirements, testing techniques, accessory design and prefabricated parts production process, as the focus of research trial production of 500 kV cross-linked cable, outdoor terminals and GIS terminal samples, to ensure product quality and stability, to ensure that the foundation of engineering applications.
　　In addition to the above projects, wire and cable material recycling technology research, high-voltage overhead transmission lines, domestic composite reinforced core material reliability and application research, high solids content paint and coating process research, cycle load capacity and real-time load capacity research is also included in the 12th Five-Year Plan research projects.

　　New product development proposals
　　In the planning, the cable branch also recommended some new product development direction for the enterprises, including 220 kV high-voltage cable sets of accessories research and development, nuclear power plants with 1E class K1 cable localization, aerospace cable development and perfection.
　　It is understood that one of the reasons hindering the application of China's domestic high-voltage, ultra-high-voltage cross-linked cable is not matching accessories, can not be supplied in sets, so the recommended development of new products, cable branch again 220 kV high-voltage cable sets of accessories included in the research and development; China's nuclear power plants have entered the accelerated development phase, and currently only one enterprise in China can produce 1E class K1 cable, production capacity to be strengthened; China's development of large aircraft industry, the need for irradiated cross-linked ethylene - tetrafluoroethylene copolymer and TFE / PI / PTFE film-wrapped sintered wire, there are still material localization and process stability issues need to be resolved; a variety of photoelectric composite cable development in the 12th Five-Year Plan period should also be strengthened, the country has begun to have applications in power cables, wire and cable for electrical equipment has not been carried out, the enterprises Should be based on the development of various industries during the 12th Five-Year Plan requirements for fiber-optic composite elevator cable, fiber-optic composite coal mine cable, fiber-optic composite marine cable, fiber-optic composite oil platform cable to be developed; motors, transformers, electronic components coils in the winding, embedding, shaping process, the general use of high-speed automated operation, the requirements of the enameled wire has excellent heat-resistant processing performance, in order to minimize the manufacturing process Damage, therefore, the need to strengthen the development of tough enameled wire.
　　In addition, high-speed rail transit cable development, emerging fiber optic development, increased capacity heat-resistant aluminum alloy development, high-voltage plastic insulated DC cable development, snow and ice resistant wire, since the damping wire, low corona wire, corrosion-resistant wire and other new wire series development is also recommended by the cable branch of new product development direction.
　　And a closer look is not difficult to find, the reason why the cable branch to choose these projects or products as the development focus of the 12th Five-Year Plan period, either for the healthy development of industry considerations, or in order to meet market demand. Such as rail transit cable, it is reported that during the 12th Five-Year Plan, China's railroad construction speed will bring huge demand for locomotive cables, communications and signal cables, the average annual demand is expected to reach 160,000 to 200,000 kilometers and 70,000 to 100,000 kilometers, respectively, urban rail transit will generate annual demand for vehicles with cables 25,000 to 30,000 kilometers, traffic with signal cables annual demand of 15,000 to 20,000 kilometers; and then Aerospace cables, due to the large aircraft manufacturing program will drive the tetrafluoroethylene copolymer insulated cables and polyimide - PTFE composite insulated cables as a representative of the high-performance light cable demand, the average annual demand is expected to reach 12,000 to 15,000 km in the future, the airport construction growth rate so that the airport power cables for power distribution, airport runway lighting cables, etc. There is a large market space, fire-resistant, fire-resistant, silicone cables, the Halogen-free low-smoke cable and other special cable demand will grow exponentially; and the motor and transformer industry demand for winding wire at an average annual rate of 1.5% to 2% in growth, it is expected that by the end of the 12th Five-Year Plan, its need for corona-resistant and special performance winding wire will have a breakthrough development, which also becomes the tough enameled wire included in the development direction of the reason.
