Wire and cable electrical signal or all the time in the transmission of you and me, transmission of information, transmission in the corner of time, whether it is 3G or 4G or can not be separated from the wire and cable signal transmission.
Wire and cable electrical signal or all the time in the transmission of you and me, transmission of information, transmission in the corner of time, whether it is 3G or 4G or can not be separated from the wire and cable signal transmission. Economic development is still not part of the development, I believe that human civilization will not only be limited in the first environment, society or to develop, wire and cable will not be replaced, there will be anything to replace the power transmission of wire and cable and electricity signal transmission.
It is understood that in foreign aluminum alloy cable has more than 40 years of use history, Europe and the United States and other developed countries aluminum alloy cable use accounted for more than 80% of the power cable, in the conductivity and copper core cable equivalent premise, aluminum alloy cable has a lot of better performance than copper core cable, such as low cost, low loss, light weight, corrosion resistance, fatigue resistance and so on. At the same time, aluminum alloy cable is also in line with low-carbon environmental protection, the construction of ecological society of new ideas, the development prospects are very considerable.
According to statistics, China’s annual output value of wire and cable has exceeded trillion, become a veritable world’s largest producer, of which about 800 billion can be replaced by aluminum alloy cable power cable, the future aluminum alloy cable market space can be imagined. Aluminum alloy cable is noisy hot, the development of aluminum alloy cable or become China’s cable industry to crack the development of difficult, chaotic, low-cost competition and other difficult problems an effective method.
Although aluminum alloy cable in China has just started, but in recent years have maintained an annual growth rate of 3-5 times, which makes aluminum alloy conductor cable or will become the next investment boom, but for China’s cable, aluminum alloy cable to smoothly promote and quickly occupy the market is also difficult.
1、Production enterprises regardless of good and bad, there are equipment, technology, no equipment, no technology is also on the aluminum alloy cable project. Aluminum alloy cable is a kind of equipment, technical requirements are relatively high new products, the key is AA8000 aluminum alloy conductor production, conductor production equipment and aluminum alloy composition formula is two technical barriers, can not break through these two technical barriers, it is difficult to produce alloy composition uniform, good conductivity, mechanical stability of aluminum alloy conductor material.
2、User units on the aluminum alloy cable know nothing, do not understand the choice of production enterprises, or in the single-minded price, which prompted a number of no equipment, no technology, no qualifications of enterprises! We recommend that users choose aluminum alloy cable production enterprises to adhere to the “three look”: a look at the equipment: mainly to see whether the production enterprises have aluminum alloy conductor production equipment and testing equipment; Second, look at the detection: conductor detection report, anti-pressure creep detection report, transition terminal 1000 thermal cycle detection report is three must report, in addition to the type test report and flame retardant and fire resistance detection report; Three look at certification: see whether the production enterprises have passed the national authority certification.
3、Design specifications and cable standards, design department is designed according to the design specifications, cable enterprises are in accordance with national standards to produce, because the current national cable standards were introduced in December 2008, and the design specifications are mostly introduced before June 2008, which caused a disconnect, although electrical designers know the advantages of aluminum alloy cables, but due to the requirements of the specifications, so in the design dare not boldly use aluminum alloy cables.
4、Standard lag, although in GB/T12706-2008 has been clearly defined that cable conductors can use aluminum alloy materials, but aluminum alloy conductors are not detailed provisions, such as alloy composition regulations, anti-pressure creep detection regulations, 1000 thermal cycle testing regulations and so on. Therefore, the National Energy Administration organized the development of the “aluminum alloy cable industry standard”, the standard is mainly based on GB/T12706, plus aluminum alloy cable many special requirements. It is hoped that this standard can play a positive role in the development of aluminum alloy cable in China.
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 chaos ring, overcapacity industry, we should be rational treatment, only users, enterprises and industry authorities work together in order to make aluminum alloy cable in China to get orderly and rapid development, in order to bring new vitality to China’s cable industry!
