Rare high-speed rail aluminum to replace copper cable into an inevitable trend

Chinese Academy of Engineering, Qing-Quan Lei predict future cable market , the application of rare earth aluminum cable high-speed rail will become increasingly widespread , replacing copper cable will become an inevitable trend. Currently, high-speed rail aluminum rods rare national standards have been issued , rare earth aluminum cable high-speed rail plan has issued national standards .

RE advent of high-speed rail aluminum one , they alerted the world .

State Department counselor , president of the China Nonferrous Metals Industry Association , said Chen full training , this is a non-ferrous material revolution.

Chinese Academy of Engineering, Qing-Quan Lei predict future cable market , the application of rare earth aluminum cable high-speed rail will become increasingly widespread , replacing copper cable will become an inevitable trend.

Experts point out that the rare earth aluminum cable only to achieve high-speed rail Chinese people " to aluminum and copper ," Dream and Revolution as the source material will be extended to the industrial revolution, driven by the industry , the optimization and upgrading of industrial structure , to achieve national strategic resources, energy alternatives .

What exactly is the rare earth aluminum high-speed rail ? It is really so magical?

The first is the tensile strength of the contest. 3 length , diameter monofilament same aluminum , copper and rare earth monofilament monofilament aluminum high-speed rail , competing against.

Tensile testing machine has just started, aluminum wire cut off , just over 10 seconds , copper is also one of two parts, Flanagan aluminum monofilament last laugh , pulled off the time required for significantly longer than the first two . Reporters picked up the broken three monofilament, monofilament only abnormal soft aluminum , can be wrapped around the fingers bent, there was not just "tough guy "-like performance.

In the fatigue test, the test flame temperature , aluminum monofilament also shows superior performance. RE outer protective cover fitted high-speed rail aluminum power cables , nearly a thousand degrees in the flames of the burner flame , cable -free retardant and dripping , only a small amount of carbide produced , and less smoke odor , the conductor is not damaged.

"This is its most popular products, completely independent research and development , the national patent . " Hebei Xin Yi , deputy general manager Wang Mans cleft proud to introduce this monofilament elongation aluminum , copper filaments than 25% higher , reaching 32 percent , " Although the gap is small, it means huge market . "

This cable as Transformers , convenient construction , waterproof , fire performance, can also work well in a variety of extreme weather conditions.

" Young Dragons " , is the most moving. Rare high-speed rail aluminum cable with independent intellectual property rights to show strong market competitiveness. " We generally do not take small orders . " Qie macro Mans said that as of October , Hebei Xin Yi only on the company's sales over a hundred million . Up to now, Xin Yi Group's sales of the product has reached 1.3 billion yuan .

Nothing , there is a new high school students , high rare earth iron aluminum turned out

Cables are nerves and blood vessels of modern society.

Copper cable manufacturing needs , currently 97% of the domestic cable is a copper cable . Our country is poor copper country , half of the copper used in the manufacture cables. On the one hand is a nation-building requires a lot of copper , on the other hand , Western countries have achieved with aluminum cable instead of copper cables more than 40 years , the penetration rate reached 80 %.

Reality is cruel, technical barriers, R & D capabilities , knowledge of new things and other reasons , the delay in making this advanced technology in the country.

Relatively abundant domestic bauxite , rare earth resources, relatively low international prices of aluminum , how to make ?

Inventions always meet people's needs appear .

In 1993, the founder of the Xin Yi Lin Zemin Cable Co., Ltd. . Innate love pondering , unyielding him, in order to improve the competitiveness of their products , vitality, determined to take a walk is not willing that others do not go the way , he began studying with aluminum and copper , aluminum manufacturing method of study power cable .

"No, do not mean we can not do it. People landed on the moon , we can . " Lin Zemin hold the breath .

At that time , Canada, the United States and France 3 aluminum cable giant, long-term monopoly on international markets and technology , domestic much information in this regard , no one is optimistic Lin Zemin .

Lin Zemin determine their own "frustrating ."

Process of the invention is hard and grueling . 2003 10 years later,林泽民in the digestion and absorption of advanced manufacturing technology home and abroad on the basis of the cable , and finally successfully developed with independent intellectual property rights of high-speed rail welcomed the Italian brand of rare earth aluminum power cables, comprehensive technical performance has reached international advanced level , breaking the Western technology monopoly.

RE aluminum cable a high-speed rail will be born in their prime .

Thus, Lin Zemin had such a " counter-attack " : Shahui aluminum cable birthplace - products exported to the U.S. for eight consecutive years , is widely used in the country to achieve 23 states, none of the quality accident.

In China, Xin Yi cable is thousands of successful projects favored , widely used in electrical , automotive, transportation , mining , shipbuilding , chemical, military and other fields .

Aluminum and copper to break the monopoly of the dominant national standards compiled

The price of copper is about 50,000 yuan / ton , while the price of aluminum is about 15,000 yuan / ton. In the case of the flow to achieve the same set , the weight of the aluminum cable is only half the copper , copper bending radius smaller than doubled and rebound performance 40% smaller than copper . Lin Zemin calculations: " In this case, simple construction worker , security increased, compared with the traditional copper cables , overall costs can be reduced by 40 % -50 %. "

The current global wire and cable market size has more than 100 billion euros . The output value of China's wire and cable business early in 2011 will be more than the United States, ranking first in the world . But compared to Europe, but also in the big but not strong situation.

Rare high- strength aluminum rail power cables appear to break this pattern. Product has 80 patents, flexible copper cables higher than 30% elongation increased by 50 % compared to copper cables , creep resistance and 40% smaller than the copper cables , respectively, through the United States, Canada , Australia and other countries certification authority.

"The Americans come here every month for some random product testing . If there is a failure is detected , immediately cancel the entry qualifications. " Qie macro Mans introduced, according to data released by the American Society of material life of rare earth high-speed rail aluminum cable copper higher than 10 years .

Currently, the group led by the Xin Yi compiled rare high-speed rail aluminum rods national standards have been issued , rare earth aluminum cable high-speed rail plan has also been issued to national standards . After Xin Yi Group's state-level enterprise technology research and development center to declare success , we can assume a national research projects .

The next few years , after completion of the project will not only form a production capacity of 10 billion yuan annual output value , and R & D center to be built cable , academician expert workstation and related ancillary facilities. Second, after the completion of all three projects , the annual output can reach 100 billion yuan .
