  Hefei evening news inquiry of hefei a through four years of scientific research to develop into "aluminum alloy cable", successfully crack the cable conductor for many years no breakthrough "with aluminum and copper" science and technology problems. Recently, the ministry of housing and urban-rural development of science and technology development promotion center organization experts to review, think comprehensive performance reached the international advanced level, the technology has great application value, can have the purpose of "to the aluminum and copper, greatly save the shortage of copper resources in China and created great economic and social benefits.
  Different from the traditional copper cable, the aluminum alloy cable adopts Gao Yanshen rate of aluminum alloy material, by joining in the pure aluminium material such as iron, and after compression, stranding process and special annealing treatment, reducing of gap "squeeze" clean aluminum alloy cross-sectional area and has good flexibility; The insulation material adopts the self-developed flame retardant silane crosslinked polyethylene and the outer layer adopts metal chain armored structure. It is understood that the current use of such technology in the cable domestic.
  According to experts, the cable safety performance of the aluminum alloy is better than that of copper core cable. When the surface is in contact with the air, it will form a thin and solid oxide layer capable of withstanding various corrosion. Because the addition of iron produces high creep properties, even in long time overload and overheat, it can ensure the stability of the connection.
  In addition, the aluminum cable is 40% less resilient than copper cable and 24% more flexible than copper cable, because the aluminum alloy cable is only 50 percent of the weight of copper cable and can effectively reduce the installation cost.
  For the same electrical performance, the direct purchase cost of aluminum alloy cable is 40% lower than that of copper cable, and the construction cost of general construction installation can be saved by more than 20%. When the copper resources are exhausted and the demand for cable is increasing, the aluminum alloy cable can not only save a lot of investment, but also will have an inestimable effect on the creation of a saving society.
  According to the development of this technology, anhui xinyi cable company controller introduces, through digesting and absorbing foreign technology, they spent nearly four years to develop into aluminum alloy cable, which broke through the home for many years without break "with aluminum and copper" technical problems. The product technology currently has the most authoritative UL certification of such products in the United States, and the products are sold in more than 20 states in the United States. The national Patent Office has now accepted seven patents from the company.
  It is reported that the aluminum alloy cable is advanced in technology and widely used in many famous engineering projects in the world, such as the Atlanta Olympic stadium, the Washington convention center, New York airport, etc. The use of aluminum alloy cables that are required to be produced and installed in accordance with the specifications has never been broken.
