aluminum and copper up national strategies or greet heyday
cable] - march 21st, shanghai electric cable research institute jointly usa general cable (chinese) released the full life cycle research report on global wire and cable industry is the first aluminum alloy cable in shanghai. research shows, aluminum alloy cable is superior in many performances of copper conductor cable. the study or will power the aluminum alloy cable ushered in the era of.
the "npc and cppcc" period, shandong qingdao cable group chairman of the board zhang sixia called for power cable with aluminum and copper rose to national strategy, and that the significant move, marking the concept with aluminum and copper, and the cable industry topic.
since the conductive copper, to there is nothing comparable to this dominant, and aluminum are playing a role of candidates. in recent years, cables with copper volume increased year by year, the annual consumption of copper cable industry is more than 5000000 tons, more than 60%. because of the relative lack of copper resources in china, copper prices higher. therefore, "al generation copper" in recent years become the industry focus, aluminum has more recognition, especially in the cable industry.
academician huang chongqi chinese academy of engineering has been serving the cable industry for more than 60 years, is a famous expert of china's nonferrous metal industry, in recent years has been committed to the promotion of the aluminum conductor cable in china. he said, "the use of aluminum conductor cable has become a major trend, the existing practice of many countries in this respect, our country also should try."
institute, special wire zhongtian technology shanghai zhongtian aluminum co., ltd. chief engineer wei you ren said, the state grid deployment of energy-saving lead pilot program, in 2012, the country network infrastructure department selected 30 pilot projects, reduce the transmission loss, saving the cost of operation and maintenance, the comprehensive effect is obvious; in 2013, the country network infrastructure will select 450 projects to carry out the pilot in 2014, the aluminum alloy wire will completely replace conventional acsr.
in the "expansion of aluminum used in electric power industry seminar", the national development and reform commission, the ministry of commerce, the state quality inspection administration, the national standardization committee and other national ministries and cable, power companies have reached a consensus, in order to determine the aluminum copper saving strategy. said the raw material department of ministry director chen yanhai, ministry of industry of power of aluminum application mechanism, improve the relevant policies, together with the relevant departments to promote related standards, strengthen supervision and standardize the management of cable industry market.
chinese nonferrous metal industry association said in january 6th this year revealed, the ministry has said to be supporting the development of aluminum alloy cable industry, bring it into the category of new materials, included in the national "industrial restructuring directory". future included in the directory, although not detailed to specific products, but the relevant project of national support, enterprises will be supported in the technological transformation, investment.
as the copper is better than aluminum electrical conductivity and thermal conductivity, the transport current loss of power energy is smaller, and was identified as the preferred material for wires and cables. but my country is rich in aluminum and copper resources, in recent years, copper prices rose too fast, with aluminum and copper is feasible to become the industry's focus of attention. compared with copper, aluminum resources in china would be more abundant, the price is much lower. moreover, if the same weight, conductivity of aluminum is strong in copper, 1 tons of aluminum conductive capacity equal to about 2 tons of copper.
electric wire and cable industry as "material typical of light industry", if taken with aluminum and copper manufacturing cable, cable enterprise cost of production will be a lot less. in recent years the concept of aluminum alloy cable gradually been accepted by the market, the market volume growth, can foreknow aluminum alloy cable application in china will continue to rise, aluminum alloy cable will open a new era of cable.
