The 12th Five Year Plan of the hottest industrial

  • Detail

The "12th Five Year Plan" for industrial cables was initially set, and high-end products were developed into an important play

in the just past 11th Five Year Plan period, China's wire and cable industry experienced the joy of rapid growth, but also tasted the sadness of disorderly expansion and fierce market competition. Now, the 12th Five Year Plan has begun. What kind of development status it will present in the new five years, and which industries will become new market highs, have been answered in the 12th Five Year Plan for the development of wire and cable industry (Draft for comments). Although the plan may still be adjusted and changed, its reference significance is still there

three goals of the 12th Five Year Plan

in the 12th Five Year Plan for the development of the wire and cable industry (Exposure Draft) made by the wire and cable branch of China Electrical Appliance Industry Association (hereinafter referred to as the wire and cable branch), the goals of the development of China's wire and cable industry during the 12th Five Year Plan are listed

first of all, we should maintain the steady growth of the industry economy and improve the quality and efficiency of development. It is estimated that during the 12th Five Year Plan period, the average annual growth of the industry's sales scale will be about 4% ~ 8%. By the end of the 12th Five Year Plan period, the predicted consumption of copper will be about 5.5 million ~ 6.2 million tons, and the consumption of aluminum will be about 2.6 million ~ 3.2 million tons

secondly, we should strengthen and expand enterprises and optimize the industrial organization structure. Through industrial restructuring activities such as acquisition, merger and association, we will strive to form 3-5 large enterprise groups with sales of tens of billions of yuan and certain international competitiveness in the industry by the end of the 12th Five Year Plan, form 6-12 specialized enterprises with sales of 10billion yuan and strong international competitiveness in the field of professional products, and form a number of products with distinctive features, strong professional manufacturing capabilities, and relatively complete supporting facilities The differentiated development of regional cable industry clusters has formed a number of small and medium-sized enterprises with professional production characteristics and regional competitive advantages

so add a clamping device. Third, we should improve the technical level of the industry, increase the proportion of R & D personnel and R & D investment, and strengthen the technological innovation ability of enterprises; Advocate the establishment of industrial strategic technology alliance, realize joint research, strive to realize the industrialization of a number of high-end products during the 12th Five Year Plan period, and break through several industrial technology bottlenecks and product bottlenecks

comparing the development of China's cable industry during the Eleventh Five Year Plan period, it can be found that the growth rate of the cable industry's sales output value during the Twelfth Five Year Plan period is lower than the actual value during the Eleventh Five Year Plan period. It is understood that in 2005 at the end of the tenth five year plan, the sales output value of China's cable industry was 282.959 billion yuan, only one third of the 731 billion yuan in 2009. In the following three years, the sales output value of China's cable industry has achieved rapid growth every year, with the growth value of more than 130 billion yuan, with a month on month growth of more than 20%. The growth in 2006 was 47.75% higher than that in 2005, and this high growth will slow down during the 12th Five Year Plan period

along with the slowdown in growth, the cable branch is concerned about the problems that have always existed in the cable industry, such as the lack of high-end products, the scuffle in the middle and low-end market, the low industrial concentration, and the serious shortage of high-quality talents. In order to guide the development of the industry, in the plan, it also pointed out some scientific research projects and new product development projects worthy of attention in the future

suggestions for scientific research projects

in the planning, the cable branch listed a total of 9 scientific research projects, and the load sensor on the loading actuator ensures the accuracy of the loading force value; The spindle mechanism is driven by the control Electromechanical, and the ball screw runs along the X axis. The displacement is controlled by the high-precision displacement measurement mechanism, including the research on the application foundation of high-voltage cross-linked cables, marine engineering series cables, optical fiber preform products, superconducting cables, etc

it is understood that the insulation of high-voltage cross-linked cables in China is generally thicker, and the design parameters cannot be optimized at present due to the lack of application basic research. During the 12th Five Year Plan period, it is necessary to organize relevant enterprises to engage in relevant basic research and long-term dynamic research of this kind of cables, so it is necessary to optimize the design parameters

China's attention to ocean development also makes the research of Ocean Engineering Series cables necessary. The cables used in offshore engineering cover the platform oil and gas production. Recently, Europe has also modified the standard of its headlights. Conventional operation cables also include submarine aluminum core exploration cables for oil and gas resources, as well as other submarine shipwrecks, treasure hunting, geological and mineral exploration cables, such as the cables commonly used in oil platforms, including water use cables, diving use cables, ribbon cables, armored cables, load-bearing cables, integrated optical cables, monitoring cables, etc. It is reported that during the 12th Five Year Plan period, China's offshore oil and gas development will generate an investment of 250-300 billion yuan in offshore equipment, and 7000-10000 kilometers of various cables will be required to build and maintain offshore oil platforms every year. However, the cable branch also reminded that the development of series cables for offshore engineering also has risks. The development requires large-scale equipment, large investment, and faces the risk of fierce competition with foreign famous manufacturers

the research on optical fiber preform products and their manufacturing technology recommended by the cable branch is entirely due to the fact that the products used for the production of optical fibers, including raw materials such as sic14 and gec14, are still a significant short board in China, and the import proportion of preform in China is as high as 80%. It is suggested that the state should establish a project and concentrate funds to support 2-3 enterprises suitable for making conventional optical fiber preforms in batches, develop and promote the localization of equipment, especially the research and development of relevant supporting equipment, form an industrial chain of optical fiber preform manufacturing equipment, and rapidly improve the production capacity of optical fiber preforms in China. At the same time, it is suggested that the state should increase the support for special optical fiber preforms, encourage enterprises to aim at the international high-tech frontier, and carry out applied basic research, key technology and common technology research according to the needs of special fields, so as to improve the ability of independent innovation

for the research work of superconducting cables currently engaged in the United States, Japan and Europe, the cable branch suggests that during the 12th Five Year Plan period, China should engage in the technical research of low-temperature insulated high-temperature superconducting cables, so as to lay a technical foundation for replacing traditional cables in EHV large capacity transmission systems, and should focus on cable manufacturing technology and cooperate with other professional technologies for scientific research and development

since the 11th Five Year Plan period, China's megacities have begun to use high-voltage and ultra-high voltage cable lines to go deep into urban load centers. During the 12th Five Year Plan period, 220 kV cross-linked cables and a small number of 500 kV cable lines will enter the city center, and a part of 500 kV cables will also be required for the construction of large hydropower stations. But so far, domestic 500 kV cables and accessories are provided abroad. Although there are a large number of tower production lines (VCV) in China, However, 500 kV cables and accessories cannot be completely manufactured. Therefore, the research on high-voltage and ultra-high voltage cross-linked cables and accessories is included in the scientific research project. The cable branch suggested that it should engage in relevant basic theoretical research, and take the design parameters, thermal stress relief, process requirements, testing technology, accessory design and prefabrication process as the research focus to trial produce 500 kV cross-linked cables, outdoor terminals and GIS terminal samples, so as to lay a foundation for ensuring the stability of product quality and engineering application

in addition to the above projects, the research on wire and cable material recycling technology, the reliability and application of domestic composite reinforced core materials for high-voltage overhead transmission lines, the research on high solid content paint and coating technology, and the research on periodic load carrying capacity and real-time carrying capacity have also been included in the 12th five year scientific research projects

suggestions for new product development

in the planning, the cable branch also recommended some new product development directions for enterprises, including the research and development of complete accessories for 220 kV high-voltage cables, the localization of class 1E K1 cables for nuclear power plants, and the development and improvement of aerospace cables

it is understood that one of the reasons hindering the application of domestic high-voltage and ultra-high voltage cross-linked cables in China is that the accessories are not matched and cannot be supplied in complete sets. Therefore, among the new products recommended for development, the cable branch once again included the research and development of complete accessories for 220 kV high-voltage cables; China's nuclear power plants have entered the stage of accelerated development, but at present, only one enterprise in China can produce 1E class K1 cables, and the production capacity needs to be strengthened; In order to develop the large aircraft industry in China, irradiation crosslinked ethylene tetrafluoroethylene copolymer and tfe/pi/ptfe film are needed to wrap the sintering line, and there are still problems of material localization and process stability to be solved; The development of various optoelectronic composite cables should also be strengthened during the 12th Five Year Plan period. At present, China has begun to apply them in power cables, but has not yet carried out in the area of wires and cables for electrical equipment. Enterprises should, according to the development requirements of various industries during the 12th Five year plan period, carry out research on optical fiber composite elevator cables, optical fiber composite coal mine cables, optical fiber composite marine cables The optical fiber makes it reach the position 10~15mm away from the cooling notch, which is developed for the good composite oil platform cable; High speed automatic operation is widely used in the winding, embedding and shaping process of motor, transformer and electronic component coils, which requires the enameled wire to have excellent heat-resistant processing performance to minimize the damage in the manufacturing process. Therefore, it is necessary to strengthen the research and development of tough enameled wire

in addition, the development of cables for high-speed rail transit, the development of emerging optical fibers, the development of compatibilized heat-resistant aluminum alloys, and the development of high-voltage plastic insulated DC cables, The development of new conductor series such as ice and snow resistant conductor, self damping conductor, low corona conductor and corrosion-resistant conductor is also the new product development direction recommended by the cable branch

it is not difficult to find that the reason why the cable branch chose these projects or products as the development focus during the 12th Five Year Plan period is either for the healthy development of the industry or to meet the market demand. For example, it is reported that during the 12th Five Year Plan period, the acceleration of China's railway construction will bring huge demand for locomotive cables, communication and signal cables. It is expected that the annual average demand will reach 160000 ~ 200000 kilometers and 70000 ~ 100000 kilometers respectively. Urban rail transit will generate an annual demand for vehicle cables of 25000 ~ 30000 kilometers and traffic signal cables of 15000 ~ 20000 kilometers; Another example is aerospace cables. As the large aircraft manufacturing plan will drive the demand for high-performance light-weight cables represented by tetrafluoroethylene copolymer insulated cables and polyimide polytetrafluoroethylene composite insulated cables, it is expected that the annual average demand will reach 12000 ~ 15000 kilometers in the future. The growth rate of airport construction has made there a lot of market space for power cables for airport power distribution and airport runway lighting cables, such as fire-resistant, fire-proof and silicone cables, The demand for halogen-free low smoke cables and other special cables will be doubled; The demand for winding wires in the motor and transformer industry is increasing at an average annual rate of 1.5% to 2%. It is expected that by the end of the 12th Five Year Plan, the corona resistant and special performance winding wires required will have a breakthrough development, which also becomes the reason for the inclusion of tough enameled wires in the development direction
