A few days ago, the Institute of Resources, Environment and Policy of the Development Research Center of the State Council released the "Strategic Planning Research on the Application of China's Copper and Aluminum Resources in the Power Cable Market" in Beijing, the report believes that from the perspective of energy conservation and environmental protection, aluminum and aluminum alloy cables are not more energy-saving than copper cables, and China's power cable industry should not promote the slogan
of "replacing copper with aluminum".
The report pointed out that in recent years, the application of aluminum alloy cables in the power cable industry has been hyped, and copper and aluminum have replaced chaos
.
Largely because of some false propaganda, customers are misled
.
For example, some companies claim that in terms of energy conservation and environmental protection, aluminum and aluminum alloy cables are energy-saving cables, which are more energy-saving
than copper cables.
According to the survey report of the International Copper Association, from the calculation and analysis of the energy consumption of the production metal, the energy consumption of primary aluminum is 2.
2 times that of cathode copper; from the analysis of comprehensive ampacity and other factors, the energy consumption of 1 ton of primary aluminum is still about 10% higher than that of two tons of cathode copper; From the calculation and analysis of industry technological progress and development planning, by 2015, the energy consumption of primary aluminum is about 2.
8 times that of cathode copper, and the energy consumption of 1 ton of primary aluminum is about 39%
higher than that of two tons of cathode copper.
According to the research report of the China Institute of Standardization, in the whole life cycle including raw material acquisition, cable manufacturing, transportation, use and recycling, the adverse environmental impact of aluminum cables is 4%
higher than that of copper cables.
In addition, the report also pointed out that whether in the stage of primary metal materials or considering the whole life cycle, the environmental performance of copper cables is better than that of aluminum cables
.
Under the same conditions, the conductivity of copper is significantly better than that of aluminum and better than that of aluminum alloy
.
Therefore, in the application stage, the end user of the product should be selected
according to the comprehensive technology, economic effect and safe operation requirements.
