Electrical signals of wires and cables are still transmitting you and me all the time, transmitting information, transmitting in the corner of time, whether it is 3G or 4G, it is still inseparable from the signal transmission of wires and cables. The economy is still in the development of the period, I believe that human civilization will not only be limited in the first environment, society is still to develop, wire and cable will not be replaced, there will be what items to replace the power transmission and electrical signal transmission of wire and cable.

It is understood that aluminum alloy cables in foreign countries have more than 40 years of use history, the use of aluminum alloy cables in developed countries such as Europe and the United States accounts for more than 80% of power cables, under the premise of conductive properties and copper cable equivalent, aluminum alloy cables have many better performance than copper cable, such as low cost, low loss, light weight, corrosion resistance, fatigue resistance. At the same time, aluminum alloy cables are also in line with the new ideas of low-carbon environmental protection and the construction of an ecological society, and the development prospects are very considerable.

According to statistics, China's annual output value of wire and cable has exceeded trillion, becoming the world's first producer, of which 800 billion or so can be replaced by aluminum alloy cable power cable, the future market space of aluminum alloy cable can be imagined. Aluminum alloy cables are noisy hot, the development of aluminum alloy cables or become an effective way to solve the difficult development of China's cable industry, chaos, low prices and other problems.



Although aluminum alloy cable in China has just started, but in recent years have maintained 3-5 times the annual growth rate, which makes aluminum alloy conductor cable or will become the next investment boom, but for China's cable, aluminum alloy cable to successfully promote and quickly occupy the market is also a certain difficulty.

At present, the main problems are:

1, production enterprises are not divided into good and bad, there is equipment, technology, no equipment, no technology is also on the aluminum alloy cable project. Aluminum alloy cable is a new product with relatively high equipment and technical requirements, the key is the production of AA8000 aluminum alloy conductor, conductor production equipment and aluminum alloy composition formula are two major technical barriers, can not break through the two technical barriers, it is difficult to produce aluminum alloy conductor material with uniform alloy composition, good electrical conductivity and stable mechanical properties.

2, the user unit of aluminum alloy cable, do not know the choice of production enterprises, or blindly compared the price, which prompted a number of no equipment, no technology, no qualification of the enterprise to prevail! We recommend that users choose aluminum alloy cable production enterprises to adhere to "three looks" : a look at the equipment: mainly to see whether the production enterprise has aluminum alloy conductor production equipment and testing equipment; Second look at the test: conductor test report, compressive creep test report, transition terminal 1000 thermal cycle test report is three necessary reports, in addition to the type test report and flame retardant and fire resistance test report; Three look at the certification: See whether the production enterprise has passed the national authority certification.

3, the design specification and cable standards of the disconnect, the design department is designed according to the design specification, the cable enterprise is produced according to the national standard, because the current cable national standard is introduced in December 2008, and most of the design specifications are introduced before June 2008, which caused the disconnect data, although electrical designers know the advantages of aluminum alloy cable, However, due to the requirements of the specification, the aluminum alloy cable is not boldly used in the design.




4, the lag of the standard, although it has been clearly stipulated in GB/T12706-2008 that the conductor of the cable can be made of aluminum alloy material, but there are no detailed provisions for aluminum alloy conductors, such as alloy composition provisions, compressive creep detection provisions, 1000 thermal cycle detection provisions and so on. Therefore, the National Energy Administration has formulated the "Aluminum alloy cable industry Standard", which is mainly based on GB/T12706, plus many special requirements for aluminum alloy cables. It is hoped that this standard can play a positive role in the development of aluminum alloy cables in our country.

In short, aluminum alloy cable is a new product for the benefit of the country and the people, we must not let aluminum conductor cable become the next chaotic, overcapacity industry, we should be rational treatment, only users, enterprises and industry authorities three aspects of the efforts, in order to make aluminum alloy cable in our country to get orderly and rapid development, in order to bring new vitality to our cable industry!

Qingdao Tianxing Cable Co., Ltd. is a technology enterprise specializing in the production of wire and cable in Shandong Province, with more than 150 sets of domestic excellent cable production equipment and testing equipment, excellent production technology, modern testing equipment, to ensure stable product quality and timely supply.
