"Replacing copper with aluminium" has a certain history in China, not to mention that in the 1950s and 1960s, Tianjin Aluminum-added Cable imported from USA Aluminum-added Cable was sold to China in 2007. For the first time, the formulation, technology and products of foreign mature Aluminum-added Cable were introduced. After eight years, the Chinese realized the great prospect of Aluminum-alloy Cable. Aluminum alloy cable projects have been launched one after another, and the domestic aluminum alloy cable market can be said to be in full swing.

On the one hand, the construction of aluminium alloy cable project is booming, and on the other hand, the criticism about aluminium alloy cable is endless. Among them, there are some people who care about the development of China's wire and cable industry, some experts who have engaged in cables for decades, and of course, some copper cable manufacturers worry that the development of aluminium alloy cable will be silkworm worm. The original market share of copper cable enterprises. Some post-perceived enterprises are also gradually awakening, especially in the past two years, copper cable enterprises are more and more aware of the crisis, and then have to voice, resist aluminum alloy cable.

So, is the technology of aluminium alloy cable mature? What is the production technology level of aluminium alloy cable in China? Why do people say that aluminium alloy cables abroad are widely used in the United States and Canada, but not in Europe? Will China's aluminium alloy cable really replace the copper cable market?

As a leading manufacturer of aluminium alloy cables in China, Baotai Industrial Development Co., Ltd. has studied and considered for many years.

I. The Development of Aluminum Alloy Cables is the General Trend

The state has made clear the strategy of saving copper by aluminium, and the future development prospects of aluminium alloy cables will certainly be good. There is no doubt that a new material and new technology will completely replace the old material and technology. The alternation between the old and the new, and the confrontation of different ideas will inevitably have a gradual process. Aluminum alloy cable originated from the United States. Aluminum alloy cable was developed in 1968. It has been used for nearly 50 years. The product occupies 80% of the market in North America. Practice has proved that the use of aluminium alloy cable for more than 50 years has not occurred any accident and is safe. Just as it was ridiculous that Qing officials objected to the construction of railways, nobody could stop the development trend of aluminum alloy cables, just as nobody could stop the historical trend of railway development.

Although there are many kinds of voices on the market, trying to stifle the development of aluminum alloy cable, but aluminum alloy cable has formed an irresistible trend.

With the vigorous advocacy of the Ministry of Industry and Information, the Ministry of Housing and Construction and the positive affirmation of the main users of electric power, such as the State Grid, industrial and mining enterprises, commercial real estate and residential real estate, it is a general trend for the aluminum alloy cable industry to keep pace with the copper cable industry. The national energy industry standard "rated voltage 0.6/1kV aluminium alloy conductor crosslinked polyethylene insulated cable" which will be implemented in September 2015 provides a strong standard basis for the smooth promotion and application of aluminium alloy cable. Regardless of market acceptance, policy orientation and standards, aluminium alloy cables have the same market position as copper cables and are members of the cable family.

Second, we should save copper by aluminium, not replace copper by aluminium, not simply replace the relationship.

We should not only see clearly the development trend of aluminium alloy cable, but also correctly look at the two sides of things. We should not vigorously blow aluminium alloy cable well, or even hold it up to the sky. Aluminum alloy cable has its inherent value and status, but it is not completely used to replace copper cable. Just like the emergence of television, it does not replace newspaper miscellaneous. Zhi, the emergence of the Internet has not replaced newspapers and magazines as well as television. Perhaps one day newspapers and magazines will die and quit the stage of history, which is also its historical mission, but in a certain historical period, it still has its own value.

Copper cable, aluminium cable and aluminium alloy cable have their own advantages in the wire and cable market. To some extent, aluminium alloy cable is an upgrade of aluminium cable. It is only because the first batch of manufacturers, marketers and public relations personnel who publicized the new thing of aluminium alloy cable should enter the cable market and let others know about this new product. The product has a concept, it will inevitably compare the copper cable with the aluminium alloy cable, resulting in an illusion that the aluminium alloy cable is to replace the copper cable. In fact, the aluminium alloy cable is mainly suitable for low-voltage civil construction. Some fire-resistant and high-risk areas are not suitable for the use of aluminium alloy cable, but for low-voltage civil construction. In the construction field, aluminium alloy cable has absolute advantages.

From the perspective of national policy, China has recently changed its basic national policy of replacing copper with aluminium instead of copper. This is a correct decision to objectively understand the cable market and a progress, which means that the national level has a clear orientation of the respective values of copper cable, aluminium cable and aluminium alloy cable.

3. Whether to use aluminium alloy cable or copper cable should be decided according to the actual situation.

After the end of World War II, in 1946, the United States formulated the technical policy of replacing copper with aluminium due to the shortage of copper resources. However, in the 1960s, the fire occurred frequently in the early installed aluminium-core electrical lines, which was mainly caused by connection failures. The performance defects of aluminium cables caused the hidden dangers of connection safety increasingly prominent. Outside, complaints from the power sector and residents continue.

Later, with the development of alloy smelting technology, a lot of research and development laboratories of some metallurgical companies did a lot of research, and finally developed electricity successfully.
