铜包铝镁数据缆的开发与研究 摘要(goldenchu@163.com) 自2005年以来，铜价飙升，用户与电缆制造商均“望铜兴叹”，寻求其替代品，世界电线电缆行业三次提出以铝代铜均是在铜价离奇高涨下产生。由于这次铜价比前两次上涨幅度都大，这次以铝代铜的广泛性要大于前两次。所以需求铜的替代品势在必行。 本文主要为电工用圆铜线、铜包铝线和铜包铝镁合金线在机械性能、电气性能等主要性能的对照，突出铜包铝镁合金线相比铜包铝在生产过程中工艺上的优点。并提出采用铜包铝镁合金线作为电缆导体材料时应具体注意的问题。制造数据缆在工艺上应具体注意哪些。由于铝的抗拉强度与断裂伸长率远小于铜，所以在加工过程中会增加很多工艺难度。而铝镁合金线提高了导体的机械强度，外包铜层又最大限度的发挥了的作用。铝镁合金线是未来导体材料的一个不错选择。铜包铝镁合金线是在铝镁芯上同心地包覆铜层,并使铜界面形成金属结合的双金属复合导线，它是铜导线的更新换代产品，二十一世纪的新复合材料。具有合理利用自然资源，降低生产成本，方便工程施工等优点，具有广阔的发展前景。CCAM data and research on the development of cable Abstract Since 2005, copper prices, cable users and manufacturers, Wang copper can not afford to seek alternatives, the world wire and cable industry on behalf of the three proposed aluminum copper are high in copper under bizarre. As a result of the price of copper on the rise over the previous two are large, the generation of copper to aluminum is greater than the two previous extensive. Therefore, an alternative to copper demand is imperative. This paper mainly used for the electrician round copper wire, copper clad aluminum wire and copper clad aluminum magnesium alloy wire in the mechanical properties, electrical properties, such as the control performance, highlighting CCAM compared to copper alloy wire in the production process technology advantages. And the use of copper clad aluminum magnesium alloy wire as a conductor material should be specific attention. Data cable manufacturers in the process which should be specific attention. The tensile strength of aluminum and as a result of the elongation at break is much smaller than copper, so the processing will increase the difficulty of a lot of technology. Al-Mg alloy wire and conductors to improve the mechanical strength, outsourcing and the maximum level of copper has played a role. Al-Mg alloy wire conductor material in the future a good choice. Copper clad aluminum magnesium alloy wire is concentric to the aluminum-magnesium core coated copper layer, copper and aluminum-magnesium and the formation of
