The main advantages of power cable and aluminum and copper to reason should be cautious
升降机电缆
Power cable is used for transmission and distribution of electric power cable, power cable is commonly used in urban underground power grid, power station leads lines, industrial and mining enterprises in the internal power supply and over the river. In the power line, the proportion of the cable is gradually increasing. Power cable is used for transmission and distribution of high power cable products in the main line of power system, including 1-500KV and above all kinds of voltage level, all kinds of insulated power cable.
The next elevator cable manufacturers to tell - power cable main advantages and aluminum and copper to reason should be cautious:
Main advantages of power cable
1 small area. Generally buried in soil or deposited arranged in the room, the channel, the tunnel, the line insulation distance is small, without a tower, covers an area of small, does not account for the basic ground space.
2 high reliability. Affected by climatic conditions and the surrounding environment, the transmission performance is stable and the reliability is high.
3 has a more favorable conditions for the development of ultra-high pressure, large capacity, such as low temperature, superconducting power cable, etc..
4 larger distribution capacitance.
5 less maintenance.
6 small possibility of electric shock.
With aluminum and copper power cable should be cautious
Recently, the State Council Development Research Center of resources environment and policy research is located in Beijing issued the China's copper and aluminum resources in power cable market application of strategic planning study ", the report believes that from the perspective of energy-saving environmental protection, aluminum and aluminum alloy cable is not more energy than the copper cable, China's electric power cable industry should not implement" Al generation copper "slogan.
Report pointed out that in recent years, the application of aluminum alloy cable in power cable industry in the fired too hot, replacing CuAl chaos clusters. To a large extent, because some false propaganda, leading customers to be misleading. For example, some companies claim that in energy-saving environmental protection, aluminum and aluminum alloy cable is energy-saving cable, energy saving than copper cable. And according to the investigation report of the International Copper Association, from metal production unit energy consumption calculation and analysis, the unit energy consumption of primary aluminum is 2.2 times of that of the cathode copper consumption; through the analysis on the comprehensive carrying capacity and other factors, 1 tons of primary aluminum consumption still better than two tons of copper cathode energy consumption higher than about 10%; from the technological progress and the development plan of calculation and analysis, by 2015, the unit energy consumption of primary aluminum is about 2.8 times that of copper cathode unit energy consumption, 1 tons of primary aluminum consumption than two tons of copper cathode energy consumption approximately 39%. According to a report from the China National Institute of standardization and reuse includes access to raw materials, cable manufacturing, transportation, use and recycling in the whole life cycle, the aluminum cable produced adverse environmental impacts to is 4% higher than that for the copper cable.
In addition, the report also pointed out that, regardless of the stage of primary metal materials, or consider the whole life cycle, copper cable's environmental performance is better than aluminum cable. Under the same conditions, the conductivity of copper is much better than that of aluminum, and it is better than that of aluminum alloy. Therefore, in the application stage, the end user of the product should be selected according to the comprehensive technical, economic effect and safe operation requirements.
