First of all, the production process of rolling black copper rods by cold rolling mills is backward, and its black copper rods have high oxide content, low electrical conductivity, poor performance, low pull-to-weight ratio, and serious consumables, energy consumption and pollution. Eliminated. Second, actively promote the optimization of aluminum rare earth processing technology. The production of electrical aluminum rods by the continuous casting and rolling process has become quite popular in China, and the performance is also good. However, the equipment still remains at the level of development in the early 1970s, and there is not much innovation in technology. To actively promote China's unique aluminum rare earth optimization processing technology. The aluminum-zirconium alloy is added to some of the key special equipment and technologies introduced, and the aluminum-fired coal-fired furnace is transformed into a molten aluminum fuel or natural gas furnace. All the coal-fired fumes and fumes emitted from the coal-fired fusion furnace are eliminated, and the flue gas is set. The filter device purifies the flue gas, improves the discharge quality, increases the yield, and reduces the cost. At the same time, the working temperature of the wire is increased from 70° C. to 150° C., and the current-carrying capacity is increased by 1.6 times. Actively introduce technology, independent innovation and development of excellent performance of wire and cable equipment. At present, the key production equipment for wire and cable leading products is compared with foreign advanced equipment. The gap in technology level is still very large, mainly reflected in low productivity, low degree of automation, high energy consumption, poor reliability, and can not meet the development of the industry. Needs, digestion and absorption are seriously delayed. The technical level, performance and reliability of special equipment for wire and cable have incalculable benefits for improving wire and cable product quality, production efficiency and material utilization. To actively introduce technology, independent innovation and development of excellent performance, high-level special equipment for wire and cable, in order to create a circular economy services wire and cable industry. I. High-temperature superconducting technology With advantages such as relatively low price, large capacity, low loss, and no electromagnetic pollution, it is highly valued internationally. Many countries have increased the development of the superconducting industry to a strategic level. In addition, major projects of “high-temperature superconducting transmission†are also supported in relevant national plans. At present, China imports about 2 billion yuan of high-temperature cables from abroad for domestic construction. It is estimated that by 2020, the market for global superconducting applications will reach 244 billion U.S. dollars (approximately 1,489.6 billion yuan), and high-temperature superconducting cables will account for about 5% of the total. Share. Therefore, R&D and application of high-temperature superconducting technology will be an important technology in the future wire and cable industry. Carbon fiber cable In recent years, it has become famous. Carbon fiber cables are used as alternatives to traditional steel-cored aluminum stranded conductors (bare wires) and are mainly used in 110kv-220kv lines. Compared to conventional ACSR, ACCC has a 29% increase in aluminum cross-sectional area and a 20% lighter weight per unit length. Therefore, with a certain allowable sag, the use of ACCC can significantly increase the transmission capacity of the line and reduce it. loss. By replacing a large number of ordinary conductors with ACCC conductors, the power grid company can realize expansion of the power grid without adding new lines, significantly saving land, towers, and engineering costs, and complying with the policy direction of energy conservation and efficiency improvement. Carbon fiber composite wires will be a revolutionary alternative to existing wires, providing new development opportunities for companies that have a strong competitive advantage in the field of carbon fiber composite wires. Three. New environmental protection cable material In the production of wire and cable, since the raw material cost accounts for more than 80% of the production cost, materials such as copper, aluminum, steel core, rubber, plastics, and sheathing are the main raw material costs, which requires the wire and cable enterprises to Designing distinctive products, saving raw materials, and developing new environmentally-friendly materials, etc. Therefore, the following measures must be considered in the future to create a circular economy in the wire and cable industry: Four aluminum copper technology: The basic research project of key technologies and process optimization of aluminum alloy cables, through the fine-tuning of aluminum alloy cable components, the aluminum alloy cable production process research, development of a good conductivity, good mechanical properties of aluminum alloy cable, The copper-aluminum transition connectors and related fittings that meet the national testing standards have been developed. The project focuses on the key technologies for solving the aluminum alloy cable's electrical performance, mechanical properties, reducing the overall outside diameter, and copper-aluminum connections. V. Aluminum rare earth optimization processing technology will be greatly developed. The production of electrical aluminum rods using the continuous casting and rolling process has become quite popular in China and its performance is also good. However, the equipment still remained at the level of the early 1970s and there was not much technological innovation. It is necessary to actively promote China's unique aluminum rare earth optimization processing technology, and add aluminum-zirconium alloys using some key special equipment and technologies introduced to convert aluminum-melted coal-fired furnaces into molten aluminum fuel or natural gas furnaces, eliminating all aluminum-burning coal-fired furnaces. The emission of coal smoke and flue gas, and the provision of flue gas filtration devices to purify the flue gas, improve the quality of emissions, increase the yield, and reduce costs, while increasing the operating temperature of the wire from 70°C to 150°C, and increasing the ampacity by 1.6 times. 6. Cable "thin craft" From the perspective of the installation of wire and cable, it is also facing a new trend of development, that is, thin jacket, cross-section miniaturization. In view of the convenience of installation, use, and transportation, while reducing raw material costs as much as possible, wire and cable products have a growing tendency of development, that is, the cable is developed to have a thinner jacket, a smaller cross-section, and at the same time ensure the current-carrying capacity. Compared to the first few, this requires an integrated wire and cable industry technology.
