One-minute sharing of knowledge about copper core cables
With the intensifying competition in the wire and cable industry, mergers and acquisitions and capital operations among large wire and cable enterprises are becoming increasingly frequent. Domestically, good wire and cable manufacturers are paying more and more attention to industry market research, especially in-depth research on changes in the business environment and customer demand trends. As we all know, most cable manufacturers only produce oxygen-free copper cores. You may be wondering why copper core cables have any advantages over aluminum cables?

It is well known that most cable manufacturers only produce oxygen-free copper cores. You may be wondering why copper core cables have advantages over aluminum cables?
Copper materials have always held a dominant position.
Since the reform and opening up, copper core cables have replaced aluminum cables. The primary reason is that domestic and international markets have achieved convergence. Although copper is more expensive, the power sector can afford it in exchange for safety, reliability, and ease of construction. Secondly, from the perspective of safety and reliability, the key point of using aluminum core power cables lies in the jointing technology and its reliability, which has some problems. Thirdly, in some cities, especially large cities, due to limited underground laying space, aluminum core power cables are not used.
Since humanity entered the electrical age, copper has held a dominant position in electrical conductors. However, for a long time, the price of copper has remained high, which has had a certain negative impact on its position in electrical conductors.
Aluminum alloy cables have certain characteristics. Economically, the advantages of aluminum alloy cables are their low manufacturing and transportation costs. However, the disadvantages of aluminum alloy cables are also obvious. The current carrying capacity is small, and adding various alloy elements to aluminum will reduce conductivity. In addition, in order to reduce the increase in the cross-section of aluminum alloy cables, although the compression coefficient has been improved through strict control of the process, the outer diameter is basically 1.2 times larger than that of copper core cables.
In terms of high-temperature performance, aluminum alloy cables have weaker performance. The melting point of aluminum is 660, while copper reaches 1080. In high-temperature environments, fire-resistant cables used at 750-1000 must also maintain their power-on function. Aluminum alloy cables cannot be used in this type of cable selection.
Copper core cables can be said to play an indispensable role in the electrical and electrical industries. Wherever there is electricity, there must be wires and cables. Wire and cable manufacturers produce a large number of wires and cables. Whether in the sky, underground, or in the water, any scientific and technological innovation research that needs to be explored and developed cannot be separated from the application and transmission of electricity and electromagnetic waves. Copper core cables play a very important role in people's lives.
With the steady and rapid growth of China's economy, the demand for copper core cables has also shown a strong momentum, accounting for a considerable proportion of the national economy and occupying a wide range of product categories. This is because copper core cables have been widely used in facilities and equipment used in the operation of the economic system. The huge power transmission system and information transmission system are extraordinary, serving all social activities and penetrating into the daily lives of all families and individuals. Wire and cable products are ubiquitous.
