Is the technology of aluminum alloy conductor mature? What is the production technology level of domestic aluminum alloy conductor? Why do some people say that foreign aluminum alloy conductors are widely used in the United States and Canada, but not in Europe? Will China's aluminum alloy conductor really replace the copper conductor Market?
 
Signi aluminum explained the technical advantages, market positioning and future development trend of China's aluminum alloy conductor as follows
 
1、 The development of aluminum alloy conductor is the general trend
 
The state has defined the strategy of "saving copper with aluminum", and the future development prospect of aluminum alloy conductor must be good. There is no doubt that a new material and new technology should completely replace the old materials and technologies. The old and new alternate, and the confrontation of different ideas will inevitably have a gradual process. Aluminum alloy wire comes from the United States. Aluminum alloy wire has been developed since 1968 and has been used for nearly 50 years. This product has been widely used, with a market share of 80% in North American countries. Practice has proved that aluminum alloy wire has been used for more than 50 years without any accidents and is safe. Blindly opposing it, rejecting it and rejecting it is just as ridiculous as the Qing officials opposed the construction of railway in those years. No one can stop the development trend of aluminum alloy conductor, just as no one can stop the historical trend of railway development.


 
Although there are still all kinds of bad voices in the market in an attempt to stifle the development of aluminum alloy wires, aluminum alloy wires have formed an irresistible trend.
 
With the vigorous promotion of major management departments such as the Ministry of industry and information technology and the Ministry of housing and urban rural development and the positive affirmation of major power users such as the State Grid, industrial and mining enterprises, commercial real estate and community real estate, it is a general trend for the aluminum alloy conductor industry to keep pace with the copper conductor industry. The national energy industry standard cross linked polyethylene insulated cable with rated voltage of 0.6/1kv aluminum alloy conductor, which will be officially implemented in September 2015, provides a strong standard basis for the smooth promotion and application of aluminum alloy conductor. In terms of market acceptance, policy orientation and standards, aluminum alloy conductor has the same market position as copper conductor and is one of the members of the cable family.
 
2、 It is "saving copper with aluminum", not "replacing copper with aluminum", which is not a simple substitution relationship
 
We should not only see the development trend of aluminum alloy wire, but also correctly view the two sides of things. We can't vigorously blow the aluminum alloy wire, or even hold it to the sky. Aluminum alloy wire has its inherent value and status, but it is not completely used to replace copper wire. Just like the emergence of television, it does not replace newspapers, magazines and the Internet, It has not replaced newspapers, magazines and television. Maybe one day newspapers and magazines die and withdraw from the historical stage, it has completed its own historical mission, but it still has its own value in a certain historical period.
 
Copper cable, aluminum cable and aluminum alloy conductor have their own advantages in the wire and cable market. To some extent, aluminum alloy conductor is the upgrading of aluminum cable. Only because the first batch of manufacturers, marketing personnel and public relations personnel who publicized the new thing of aluminum alloy conductor wanted to enter the cable market and let others have a concept of this new product, It is inevitable to compare copper conductor with aluminum alloy conductor, resulting in an illusion that aluminum alloy conductor is to replace copper conductor. In fact, aluminum alloy conductor is mainly suitable for low-voltage civil buildings, and aluminum alloy conductor is not suitable for some fire-resistant and high-risk areas. In the field of low-voltage civil buildings, aluminum alloy conductor has absolute advantages.
 
From the perspective of national policy, China has not mentioned the basic national policy of "replacing copper with aluminum" but "saving copper with aluminum" recently, which is a correct decision to objectively understand the cable market and a progress, which means that the national level has a clear positioning for the self value of copper conductor, aluminum cable and aluminum alloy conductor.
 
3、 Whether to use aluminum alloy conductor or copper conductor shall be determined according to the actual situation
 
In 1946 after the end of the Second World War, the United States formulated the technical policy of "replacing copper with aluminum" to deal with the shortage of copper resources. However, in the 1960s, frequent fires occurred in the early installed aluminum core electrical lines, which were basically caused by connection faults. The potential safety problems of connection caused by the performance defects of aluminum cables became increasingly prominent, and the power departments and residents complained constantly.
 
Later, with the development of alloy smelting technology, the R & D laboratories of some metallurgical companies did a lot of research, and finally developed aluminum alloy for electrical purposes. In the further research, it is found that aluminum alloy has very excellent characteristics, such as greater strength, higher ductility, better creep resistance and so on. Later, these aluminum alloy materials were listed in the 8000 Series aluminum alloy product catalog by the American Aluminum Association.
 
From the perspective of the scientific properties of metal materials, it is impossible to completely replace copper with aluminum. Copper cables and aluminum alloy wires have their own advantages and specialties. Aluminum alloy wires cannot be used for copper cables, but aluminum alloy wires can be used for aluminum alloy wires. It is completely feasible to maximize the use of aluminum alloy wires in terms of electrical performance, mechanical performance and economic performance, Save copper resources for the country and maintain the safety of strategic materials.
 
Throughout the long history of "saving copper with aluminum" in the world, according to the national conditions and the level of science and technology, countries are different, walking and stopping or even repeated, but the overall development is gradual. Therefore, the prospect of "saving copper with aluminum" is generally clear. However, whether to use copper or aluminum wires and cables should be determined by the design and users of the terminal according to the comprehensive technical and economic effect.
 
4、 The popularization and application of aluminum alloy conductor is in line with China's national conditions
 
There is no doubt that copper resources are important strategic materials of the country. As early as 1917, Li Dazhao pointed out in his article war and copper, "The relationship between copper and war is as important as this. Our government should make money when it is collected and destroyed, and save it for appropriate purposes. Be careful not to allow it to be continuously transported overseas. It is not only an important product in the financial sector, but also a sharp weapon in the battlefield in the future." he called on the government to reserve copper resources for emergencies.
 
Although China has defined "replacing copper with aluminum" as a national technical policy as early as 1957, the promotion and application of aluminum core and aluminum alloy core cables have been affected due to poor implementation and other reasons. As a new product, new material and new technology, users are bound to have a gradual acceptance process in the process of market promotion and application.
 
The meaning of conductor "saving copper with aluminum" means that the cable products using copper use copper. The products that can use copper or aluminum alloy as conductors can only be applied after scientific experiments and successful practical trials. Blind promotion is opposed.
 
The driving force of "saving copper with aluminum" in China's cable industry comes from the following aspects:
 
(1) The annual consumption of copper in the industry is very large. In 2011, the consumption of copper and aluminum in the industry reached 4.84 million tons (accounting for about 1 / 3 of the world's copper conductor output) and 2.2 million tons respectively, and the copper used for electrical engineering has always belonged to 99.95% and 99.99% of high-grade copper. However, China's copper reserves are lack, and there is not much waste copper recovered at present, so it depends on import;
 
(2) The soaring world copper price has seriously compressed the profit margin of cable products;
 
(3) It is proved by trial that aluminum alloy cable products have achieved good technical and economic results.
 
There is only one word difference between "replacing copper with aluminum" and "saving copper with aluminum", but the result is today's "dispute between copper and aluminum" , it's no hurry. Aluminum alloy wire is not to grab the rice bowl of copper wire, but to replace copper wire in different application ranges under the conditions in line with China's national conditions, so as to save the strategic resources of the state and society and meet the overall interests of the state, society and users.


 
5、 Military quality makes aluminum alloy wires go further
 
At present, the current situation of China's aluminum alloy conductor industry is a mixed market of a few foreign brands and domestic brands. In addition, there are relevant national standards and standards of the Ministry of energy on the implementation standards of aluminum alloy conductor. Although these standards are the same, there are different opinions on which standard is the main standard. How will China's aluminum alloy conductor industry get rid of this chaotic situation The fundamental way out is to require the industry to carry out product R & D and production towards China's highest quality standard - "military quality".
 
As we all know, the highest level of product quality is military quality. Military quality represents advanced product technology, exquisite workmanship, rigorous management, high standards and strict requirements. Its quality is unmatched by civil products, including foreign brands.
 
The recognition of military quality in people's mind is very high. According to the survey, more than 96% of people agree that military quality is synonymous with personality, strength, durability and excellent performance. Under the same use conditions, most people will choose to use military quality products instead of other commercial products. Use "military quality" Building the highest quality of China's aluminum alloy conductor is the best way for cable enterprises to enhance the competitiveness of Chinese brands. With the deepening of reform, the change of international security situation and the development trend of military enterprises, "military civilian integration, military civilian integration and military civilian integration" has become a common development model of military industry.
 
Signi aluminum, which leads the industry with product military quality, has a strong quality awareness and management heritage. It has high standards and strict requirements in quality management, adheres to the craftsman spirit of continuous innovation and accurate manufacturing, always requires product quality with military quality, reflects value with quality and creates value with quality.
 
In view of the development trend of the domestic aluminum alloy conductor market, signi aluminum took the lead in entering the domestic aluminum alloy conductor market with a new look of American technology and military quality. It is a farsighted and wise choice for enterprises with military product quality management requirements to carry forward the past and forge ahead into the future, and engage in continuous technological innovation and product production management of aluminum alloy conductors with higher standards and starting points.
 
Aluminum alloy conductor manufacturers develop products according to the requirements of "military quality", which has far-reaching impact and significance on the development of civil products industry, the transformation of military products to civilian products, the integration of military products into civilian products, the vigorous improvement of independent innovation ability, the acceleration of industrial structure upgrading, the realization of new breakthroughs in adjustment and reform, as well as the promotion of new technologies and new products, the extension of industrial chain and the future development of enterprises.
