线缆工业是铜最重要的消费市场,全球市场的精铜约70%用于线缆生产,因此,全面了解线缆工业对于了解本文提到的铜需求的驱动器十分必要。线缆工业由于生产技术多样、原材料多样,所以产品种类十分丰富。在铜成为用于线缆导体加工的主要材料之时,也采用了其他材料加工制造线缆,在某些应用方面,铜的主导地位正在受到挑战,铝是最常用的替代材料,还有一些其他材料。例如,超导体或者碳纳米管。但是,笔者预计,铜将继续成为未来用于电缆导体的最常用材料。
The cable industry is one of the most important consumer markets for copper. Around 70% of the refined copper in the global market is used for cable production, so a thorough understanding of the cable industry is necessary to understand the drivers for the copper requirements mentioned in this article. Cable industry due to diverse production technology, raw materials and diverse, so the product range is very rich. While copper is the main material used in the processing of cable conductors, other materials are also used to manufacture the cables. In some applications, the dominance of copper is being challenged. Aluminum is the most commonly used alternative material, and some other materials. For example, superconductor or carbon nanotube. However, I predict that copper will continue to be the most commonly used material for cable conductors in the future.
