The green innovation technology exchange conference for new transmission lines was held in guiyang, capital of southwest China's guizhou province, on oct 27 and 28, 2017. [photo/xinhua]This conference is sponsored by China electric power enterprise federation and undertaken by zhongtian technology group.Through experts' special reports, technical exchanges, etc., the participants have a deeper understanding of the application of aluminum alloy at home and abroad, and the application prospect of wire is more clear.

Zhang guowei, director of the production department of state grid corporation of China, said that in recent years, China's power grid has maintained a high-speed development, and the current power grid specifications exceed the conventional ones.The construction of these uhv landmark projects has become a sign that China's power grid is in a leading position in the world.These advances are an important aspect of the country's development strength and the result of joint innovation and efforts in the equipment and material manufacturing industries within the power grid.Without the backing of innovation in material and equipment manufacturing, there will be no solid foundation for the development of power grid enterprises.Zhongtian technology group as one of the backbone of the domestic power wire manufacturing enterprises, according to the power grid development needs, real time series wire research and development of various operating conditions, the production of steel core aluminum stranded wire and heat-resisting aluminum alloy conductor, soft steel core aluminum stranded wire, aluminum wire and other special line is widely used in north China, central China, northeast, northwest power grid of 110 kv, 220 kv, 500 kv, 750 kv and 1000 kv ac line and plus or minus plus or minus two 660 kv and 800 kv dc lines for the innovative development of state grid corporation provide strong support.

Chen jianfu, deputy director of the production and technology department of China southern power grid corporation, said that due to the rapid development of the world economy, how to build a sustainable technology and militarization is the current development theme.Our line construction occupies a lot of land resources and consumes a lot of materials.And our line operation efficiency is not very high, southern power grid has the same problem.After several years of rapid construction, China southern power grid has been improving its power grid.In recent years, we have been exploring how to further improve the carrying capacity of the line, reduce the occupation of resources and reduce the use of relevant materials.We hope that the mature new technology can be promoted and applied in the production and operation of our power grid construction as soon as possible.

Southern power grid high dodson TB, transit of the institute of science and technology, senior engineers, senior expert Zhao Lianqi, east China electric power design institute senior engineers Ye Hongsheng, director of the China electric jian-cheng wan research institute, Shanghai electric cable research institute, southwest electric power design institute, director of the liu senior engineers Mr. Wang, guangdong electric power design institute, a senior expert Pan Chunping, hunan electric power design institute set up total li Lin, zhongtian technology group is lu wei, general manager of grid division, zhongtian, director of the institute of science and technology lead YouWei, zhongtian technology group hardware brand manager at new countries and so on has made the conference speech.

Experts on the application of heat-resisting aluminum alloy conductor thought under the new situation, strong strength in the steel core aluminum alloy on the large span, the application of technology present situation and development trend of wire, steel reinforced forming aluminum alloy wire in the application of ice, strong steel reinforced high strength heat-resistant conductor on the large span of the application of aluminum wire, aluminum alloy core application prospect, hardware as well as the production technology of high quality aluminum alloy and so on several aspects has carried on the exchange, fully recognize the application of the aluminum alloy wire on the trend.

At present, many countries in the world use aluminum alloy wire on the line, mainly high strength aluminum alloy and heat resistant series of aluminum alloy, a lot of series of products have formed the standard, some countries and regions use proportion is greater than our country.Under the trend of new technology application, China's special aluminum alloy conductors such as medium-strength aluminum alloy conductors and high-strength heat-resistant aluminum alloy conductors have been studied and applied a lot.

The experts at the meeting believe that the manufacturing level of aluminum alloy wire in China is also improving year by year, providing more choices for power grid engineering and adopting appropriate technical schemes and products, which is also our goal.Under the new situation, low-carbon economy and green and harmonious society require us to be forward-looking, in line with the idea of economy, energy saving, reasonable and environmental protection, we need the power transmission department, the line design department for further research and application discussion.

State grid, China southern power grid, China institute of electrical technology, major electric power design institutes, north China electric power university, Shanghai electric power college, guizhou electric power company and relevant government leaders attended the conference.
