Controversial aluminum alloy cable

Aluminum alloy cable "aluminum instead of copper", the industry has been arguing
.
Especially in the past two years, copper cable companies have become more and more crisis, and then have risen up to speak out and boycott aluminum alloy cables
.
Is the technology of aluminum alloy cable mature? What is the production process level of domestic aluminum alloy cable? Why do some people say that foreign aluminum alloy cables are widely used in the United States and Canada, but not in Europe? Will China's aluminum alloy cable really replace the copper cable market? Here's a transcript of interviews with industry professionals:

First, the development of aluminum alloy cable is the general trend

There is no doubt that the country has made clear the strategy of "aluminum and copper", and the future development prospects of aluminum alloy cables must be good
.
A new material and new technology should completely replace the old materials and technology, and the alternation of the old and the new, the confrontation of different ideas and concepts, there will inevitably be a gradual process
.
Aluminum alloy cable from the United States, since 1968 developed aluminum alloy cable, the use of nearly 50 years, the use of the product has been quite common, in North American countries market occupancy rate of 80%, practice has proved that aluminum alloy cable used for more than 50 years without any accidents, is safe
.
Blindly opposing it, rejecting it, rejecting it, just as it is ridiculous that Qing Dynasty officials opposed the construction of railways, and no one can stop the development trend of aluminum alloy cables, just as no one can stop the historical trend of railway development
.

Although there are still various objections on the market, in a vain attempt to stifle the development of aluminum alloy cables, aluminum alloy cables have formed an unstoppable trend
.
With the vigorous promotion of the Ministry of Industry and Information Technology, the Ministry of Housing and Urban-Rural Development and other major management departments and the positive affirmation of the State Grid, industrial and mining enterprises, commercial real estate, residential real estate, etc.
, the aluminum alloy cable industry and the copper cable industry go hand in hand
.
The national energy industry standard "rated voltage 0.
6/1kV aluminum alloy conductor XLPE insulated cable" that will be officially implemented in September 2015 provides a strong standard basis
for the smooth promotion and application of aluminum alloy cable.
No matter from the perspective of market acceptance, policy orientation, and standard specifications, aluminum alloy cable has the same market position as copper cable and is a member of the
cable family.

Second, it is "aluminum section copper", not "aluminum instead of copper", not a simple replacement relationship

Aluminum alloy cable has its inherent value and status, but not completely used to replace copper cable, just as the emergence of television, did not replace newspapers and magazines, the emergence of the Internet, did not replace newspapers and magazines and TV, maybe one day newspapers and magazines end their lives, out of the historical stage, that is also it completed its own historical mission, but in a certain historical period, it still has its own value
.

Copper cable, aluminum cable, aluminum alloy cable in the wire and cable market has their own strengths
.
In fact, aluminum alloy cable is mainly suitable for low-voltage civil construction fields, some fire-resistant, high-risk areas are not suitable for the use of aluminum alloy cables, and in the low-voltage civil construction field, aluminum alloy cables have absolute advantages
.
From the perspective of national policies, China has recently not mentioned "aluminum instead of copper", but changed to the basic national policy of "aluminum section copper", which is the correct decision to objectively understand the cable market and is a kind of progress, which means that the national level has a clear positioning
for the respective values of copper cables, aluminum cables and aluminum alloy cables.

Third, the use of aluminum alloy cable or copper cable should be decided according to the specific actual situation

Whether to use aluminum alloy cable or copper cable should be decided
according to the specific actual situation.
From the scientific performance of metal materials, it is impossible to completely replace copper with aluminum, copper cable and aluminum alloy cable have their own advantages and characteristics, the use of copper cable can not use aluminum alloy cable, but can use aluminum alloy cable, on the maximum use of aluminum alloy cable, whether from electrical properties, mechanical properties, economic performance are completely feasible, for the country to save copper resources, maintain the safety of
strategic materials 。 Throughout the history of the world's
"aluminum section copper", according to the national conditions and the level of science and technology, countries are different, stop-and-go and even repeated, but the overall development is gradual, so the prospect of "aluminum section copper" is generally clear.
However, whether to use copper or aluminum wire and cable, should be determined by the design of the end use and the user according to the comprehensive technical and economic effects
.

Fourth, the promotion and application of aluminum alloy cables is in line with China's national conditions

As early as 1917, Li Dazhao pointed out in his article "War and Copper", "The relationship between copper and war, as it is hereby urgent, our government should collect the money and store it for appropriate purposes, and be careful not to let it be continuously transported overseas, which is not only a heavy product in the financial world, but also a weapon on the battlefield in the future
.
" "Call on the government to stock up on copper resources in case of emergency
.
Although China has identified "aluminum instead of copper" as a national technical policy as early as 1957, due to poor implementation and other reasons, it has affected the promotion and application
of aluminum core and aluminum alloy core cable.
As a new product, new material, new technology, in the process of market promotion and application, users will inevitably have a gradual acceptance process
.

The meaning of conductor "aluminum section copper" refers to the use of copper cable products on copper, for products that can use copper or aluminum alloy as conductors, it is necessary to undergo scientific experiments, with the actual trial of successful products, in order to apply, oppose blind promotion
.
"Aluminum instead of copper" and "aluminum section copper", only one word difference, but the result is today's "copper and aluminum dispute", why fry, aluminum alloy cable is not to grab the rice bowl of copper cable, but in different application range, in line with China's national conditions to use the condition, the replacement of copper cable, in order to save the strategic resources of the country and society, in line with the overall interests
of the country, society and users.
