60--70 years, high-speed global copper prices to rise, due to political factors, the copper as strategic goods subject to trade controls, extensive use of aluminum as the country's main transmission cable conductor material, "In aluminum and copper" has become a technology policy generally follow the electrical industry, Selection copper conductor cable needs to apply to the competent government department report. So civil trunk and feeder lines are used AAC Conductor. The disadvantage of AAC Conductor(AA1350) is mainly reflected in the following aspects:
1. Poor mechanical strength, easily broken.
2. Easy to creep, requires frequent fastening screws.
3. Easy to overload fever, but there are security risks.
4. There is no good solution to copper and aluminum transition connection problems, especially in the wire cloth.
The issue is not just a problem facing the country, the world's cable industry is also facing the same problem. With the improvement of the international situation, the implementation of China's reform and opening up, we can easily import large quantities from overseas copper resources, and the spread between the little copper and aluminum to aluminum and copper in the country gradually fade; at the same time, actively developing overseas The new AAC Conductor, AAC Conductor and solve connectivity problems terminals, and ultimately the United States and Europe, a large number of applications in the distribution line AAC Conductor.
