Technical analysis of the ACSR cable industry

With the development of China's power industry, the requirements for supporting industries are increasingly high, ACSR cable industries as power supporting an important part are no exception, faced with the need to upgrade to meet the needs of China's power development. The future of ACSR cable companies should improve technology, conservation of raw materials, the development of new environmentally friendly materials, and other aspects. According to the author's judgment, that the future of the future development of ACSR cable industry technology is mainly related to the following aspects.

With the development of carbon fiber in recent years and more quickly, there is a possibility that the future may be a carbon fiber cable replacing traditional ACSR cable. Carbon fiber cable is the traditional ACSR cable (bare wire) alternative product, mainly used in 110kv ~ 220kv lines. Compared with conventional steel core aluminum wire (ACSR cable), ACCC cross-sectional area of aluminum increased by 29%, and 20% lighter weight per unit length, which sag under certain circumstances allow, can greatly enhance the use of ACCC line transmission capacity, reduce loss. 

Power company by a large number of ordinary wire replaced ACCC conductor can be achieved without new line grid expansion, significant savings in land, towers, engineering costs, in line with the policy direction of energy efficiency. Carbon fiber composite wire will be a revolutionary alternative to the existing wire. Thus providing new opportunities for those companies in the field of carbon fiber composite wire has a strong competitive advantage.

HTS technology will be the next big development. Since the high-temperature superconducting cable has a relatively low price, high capacity, low loss, no electromagnetic pollution, and other advantages, highly regarded in the international community, many countries have developed a superconducting industry rose to a strategic height. China has achieved a major breakthrough in high-temperature superconducting technology. In August, at the International Thermonuclear Experimental Reactor (ITER) program headquarters official site supervision, the maximum length of the superconducting cable --765 meters CB (factory standard) superconducting cable conductor ITER device operating in silver colored Long-company line.

Meanwhile, on the basis of high-temperature cables, the relevant state plans are also set to "high-temperature superconducting power transmission" for major project support. At present, China's annual imports from overseas high-temperature cables for domestic construction are about two billion yuan is expected to 2020 global superconducting applications market will reach 244 billion US dollars (about 1.4869 trillion yuan), about 5% of the high-temperature superconducting cable share.

So the development and application of high-temperature superconducting technology will be an important technology in the future ACSR cable industry.
