What is the use of aluminum alloy cables with only three percent copper rate

In 2014, China's aluminum alloy cable market was worth nearly 13 million yuan, but the aluminum alloy copper replacement rate was far lower than the world level
.
So far, the copper replacement rate of aluminum alloy and aluminum-magnesium-silicon alloy in the United States has reached 70%~75%, the copper substitute rate of aluminum alloy in Japan has reached 55%, and the copper substitute rate of aluminum alloy in China is only 3%~5%.

A few days ago, ResearchandMarkets, a well-known foreign market research company, released the "2015~2020 China Aluminum Alloy Cable Market Analysis Report"
.

The price of copper directly determines the production cost
of cables.
As we all know, the amount of copper used in copper cables is very large, and most of the production costs must be found from raw materials
.
The cost of aluminum is relatively low, and it is an ideal material
to replace copper.
In the case of the same section and length, the conductivity of aluminum alloy is 61.
8% of copper, the current carrying capacity is about 78% of copper, the specific gravity of copper is 8.
9 g/cm³, the specific gravity of aluminum is 2.
7g/cm³, and the same cross-sectional area of the cable, the weight of the aluminum alloy cable is only more than
half of the copper core cable.
Due to the light weight of aluminum alloy cable, it is especially suitable for large-span buildings, such as stadiums, convention and exhibition centers and other buildings of cable laying, the use of aluminum alloy cable can reduce the load on the building steel structure, save the cost
of steel structure.
In addition, the use of aluminum alloy cables for high-rise buildings can reduce the difficulty and workload of vertical cable laying, save labor costs, and also reduce the risk of
body damage due to cable construction.
Since the melting point of aluminum is 660 °C, most of the fire lines that require continuous power supply in the event of a fire will use aluminum alloy cables
.

Aluminum alloy cable from the United States, since 1968 developed aluminum alloy cable, used for nearly 50 years, the product has been used quite commonly, in North American countries market occupancy rate of 80%.

15~20 years ago, aluminum alloy cables were widely used in developed countries such as Europe, America and Japan, and became the main products
of cables used in power transmission and distribution systems in many developed countries.

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
.
Although aluminum alloy cables started late, it is the general trend
to go hand in hand with copper cables.
Some predicted analysts said that in the next ten years, China's new energy market will usher in rapid development, which undoubtedly provides huge development opportunities
for aluminum alloy cables.

The driving force of China's cable industry "with aluminum and copper" comes from the following three aspects
.
(1) The annual copper consumption of the industry is very large, in 2011, the industry's copper and aluminum consumption has reached 4.
84 million tons (about 1/3 of the world's copper conductor production) and 2.
2 million tons, and the electrical copper has always been high-grade 99.
95% and 99.
99% copper
.
However, China's copper deposits are lacking, and there are not many scrap copper recovered, relying on imports; (2) The soaring copper price in the world has seriously compressed the profit margin of cable products; (3) After trial proof, there are aluminum alloy cable products
that have achieved good technical and economic effects.
In August last year, the State Grid Corporation of China included aluminum alloy cables in the new technology promotion catalog
.
The national energy industry standard "rated voltage 0.
6/1 kV aluminum alloy conductor cross-linked polyethylene insulated cable" will be officially implemented on September 1, 2015, which has brought a perfect end to the "battle of the right name" 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.

Jiang Huajun, general manager of Far East Smart Energy Co.
, Ltd.
, said in an interview with reporters, "Any new technology, new technology, new things in the initial stage, will face a large number of denial and criticism, but with the continuous pace of history, old concepts will inevitably be eliminated, new things will gradually be recognized and accepted, and then widely appear in every corner of social life, aluminum alloy cable is a good example
.
" "Although there are still a variety of singing voices on the market in an endless attempt to stifle the development of aluminum alloy cables, aluminum alloy cables have formed an unstoppable trend
.

From the perspective of industry development and market trends, in the aluminum alloy cable industry, the future direction of technological progress, production structure adjustment, and product supporting requirements of enterprises are already clear
.
The product brand level, user group composition, demand distribution, and mainstream forces leading the market in the market have been basically clear
.
Some experts believe that the probability of China's aluminum copper replacement is still in a very backward stage at this stage, and it will take about 10 years to replace aluminum copper in the short term, but with the development of China's renewable resources industry and the vigorous opening of the market government, it is believed that the probability of China's aluminum copper replacement in the near future will be greatly improved
.
By then, China's aluminum alloy industry market will exceed 300 billion yuan
.

Jiang Huajun said in an interview with reporters, "It is unrealistic for aluminum alloy cables to completely replace copper cables, copper and aluminum are excellent conductors, and aluminum can be used where aluminum can be replaced, but copper must be used where copper is needed
.
" "In the case where copper can also be used, it is necessary to go through scientific demonstration and practical application before deciding whether aluminum can be used instead
.
" Replacing copper with aluminum "requires incremental development
.

The promotion and application of aluminum alloy conductor cable series products can not only save copper resources for China, but also resolve excess electrolytic aluminum production capacity, which is of great benefit to China's construction of
a conservation-oriented society.
Far East Cable has been actively advocating green cable products to serve customers and the whole society
.
This development concept has promoted the maturity and development of aluminum alloy conductor cable series products, conformed to the trend of industry development, and met the continuous development of customer market demand
.
This also coincides
with the concept of "building a conservation-oriented society and developing a circular economy" proposed by the state.
It is foreseeable that the application of aluminum alloy cable products in China will continue to rise, and the aluminum alloy conductor cable series products of Far East Cable will also open a new cable era
