Aluminum cable will show a rapid growth trend
时间:2014-09-02   点击:(2745)

Copper is an important strategic materials, has also been an important raw material in the production of copper cable. Widespread use of copper cables, copper cables for over-reliance led by copper wire and cable industry to China accounted for more than 60% of copper content with. 
 
From a domestic R & D and smelting aluminum conductor business that, at present, China has proven copper resources have mostly been the depth of development, China's copper reserves of about 26 million tons, while China's actual use of about 5 million tons per year of copper, copper cable amount of about 70% of China's total copper consumption. 70% of copper concentrate per year rely on imports, if not dependent on imports, Chinese copper resources can use up to five years. 
 
It is reported that, in order to meet the rapid expansion of domestic demand, Chinese companies have invested in the development of overseas copper resources, and now the world's top ten of the world's mining giants control nearly 75% of mine production, highly resource monopoly. Since the pricing right to speak not in China, leading to a sharp rise in the cost of Chinese copper imports from abroad. In this regard, insiders told reporters: "smelting copper concentrate imported from abroad, the domestic refining smelting enterprises per one ton of copper on the loss of 1-2000 yuan." 
 
Excessive domestic demand caused by wire and cable products for the dwindling resources of copper, copper prices rose after another, so that the wire and cable industry felt unprecedented pressure. The next few years, smart grid, nuclear power, railways, airports, construction, household appliances and other industries to flourish, wire and cable products demand will grow rapidly, demand for wire and cable market is still huge room for growth. 
 
On the one hand is highly dependent on copper cables, market demand, on the one hand is a shortage of copper resources, soaring prices, a substantial increase in costs, and aluminum resources in China is a big country, very rich in reserves of about 2.7 billion tons. How limited copper resources, to meet the dramatic growth of the domestic market needs? Experts told reporters: R & D has a high-tech, high-performance aluminum cable products, aluminum instead of copper is the only way to break the bottleneck of. 
 
In recent years, our country in terms of aluminum instead of copper made ​​unremitting exploration. After years of scientific and technological enterprise successfully developed aluminum cable, both in electrical performance and mechanical properties, such as the full realization of aluminum instead of copper major technological breakthrough. 
 
Unlike traditional cable cable with aluminum production process and technology and the development of new high-tech aluminum conductor power cable, compared with copper cable ampacity their safety, conductivity and safety, conductor resistivity, especially sectional flow exactly the same and even better than traditional copper cables, made up hard aluminum cable conductor as many inadequacies, to solve the aluminum cable safety properties, electrical properties, mechanical properties in many major technical problems unresolved. 
 
The industry generally believes that compared with traditional copper cable, the cable under the conductive properties of the alloy and copper equivalent premise, lighter and more flexible, completely changed in the past aluminum cable poor mechanical strength, low resistance to fatigue and joint easy Disadvantages accidents, etc., to protect the continued stability of the cable in case of prolonged overload and overheating cable connections. In addition, make up the traditional copper cables with memory effect and high rebound performance and other defects, reduce the line loss. 
 
Insiders pointed out: in Europe and the United States, France, Canada and other developed countries, accounted for using the percentage of all aluminum conductor cables up to 90%. In China, aluminum cable though just started, but the rapid development in recent years have maintained a growth rate of 3-5 times a year. The next five years China's aluminum cable market will speed development, the formation of more than 200 billion yuan market scale, market demand outlook is very impressive.
