[China Aluminum Industry Network] "The 8000 series aluminum alloy conductor cable may replace the copper cable." On June 25th, the 2013 Asian Cable Forum held in Tianjin and the 2013 (23rd) national wire and cable special equipment At the exhibition, technical exchange, and purchase ordering conference, Chen Shande, a senior engineer at the Shanghai Cable Research Institute, said.
Chen Shande said that currently China’s copper resources are in short supply, and many people in the wire and cable industry have advocated replacing aluminum with copper. However, the pure aluminum cable also has its many shortcomings, and aluminum alloy power cable makes up for its many shortcomings: to improve the cable's electrical conductivity, bending performance, creep resistance and corrosion resistance, etc., to ensure that the cable is Maintains continuous and stable performance over long periods of overload and overheating. If you use 8000 series aluminum alloy conductors to make cables, then it is not a small increase, it can not only greatly improve the aluminum alloy cable conductivity, high temperature resistance, but also can solve the problem of pure aluminum conductor electrochemical corrosion, creep and other issues . The electrical conductivity of the 8000 series aluminum alloy is 61% higher than that of the commonly used reference material copper IACS (percentage of electrical conductivity). Under the same volume, the actual weight of the aluminum alloy is about one third of that of copper. According to this calculation, under the premise of meeting the same conductivity performance, the length of the 8000 series aluminum alloy cable under the same weight is twice that of the copper cable. Therefore, the weight of the 8000-series aluminum alloy conductor cable at the same current-carrying capacity is about half that of the copper cable.
In addition, he said, due to the light weight of the 8000 series aluminum alloy conductor cable, it will greatly reduce the carbon emission during transportation and installation. At the same time, the 8000 series aluminum alloy conductor cable does not contain heavy metal elements and is environmentally friendly. It can be said that the 8000 series aluminum alloy conductor cable is a kind of energy-saving, material-saving and environmental protection cable. Under the increasingly scarce environment of copper resources in China, it may replace the copper cable.
