State Grid Corporation of China recently announced，Currently the highest voltage level in the world、Maximum conveying capacity、The Zhundong-Wannan ±1100 kV UHV DC transmission project with the longest transmission distance and the Sutong 1000 kV AC UHV GIL integrated pipe corridor project that used UHV GIL technology in an important transmission channel for the first time in the world were launched in September Put into seabet casino review at the end of the month。
The Zhundong-Wannan project starts in Changji Hui Autonomous Prefecture, Xinjiang，The destination is located in Xuancheng City, Anhui，Via Xinjiang、Gansu、Ningxia、Shaanxi、Henan、Anhui 6 provinces (regions)，The total length of the line is 3324 kilometers，Project investment 40.7 billion yuan。Based on the successful breakthrough in ±800 kV DC transmission technology，State Grid organizes domestic and foreign joint research，Overcame the ±1100 kV DC transmission system solution demonstration、Extra long air gap insulation、Overvoltage depth control、World-class problems such as electromagnetic environment control，Achieved DC voltage、Conveying capacity、Comprehensive improvement of AC grid side voltage，DC voltage level increased from ±800 to ±1100 kV，Transmission capacity increased from 6.4 million kilowatts to 12 million kilowatts，Economic transmission distance increased to 3000-5000 kilometers，Transmission loss per thousand kilometers reduced to about 1.5%，Further improve seabet casino review transmission efficiency，Save precious land and corridor resources。
The Sutong GIL (Gas Insulated Metal Enclosed Transmission Line) integrated pipe gallery project is also currently the highest voltage level in the world、Maximum conveying capacity、The ultra-long distance GIL innovation project with the highest technical level。The project starts from the North Bank (Nantong) transfer station，Ends at Nan'an (Suzhou) transfer station，Tunnel length 5468.5 meters，Shield diameter 12.07 meters，It is currently the largest burial depth in China、Large underwater tunnel with the highest water pressure。Revolving around "a successful operation、Long-term safe operation” goal，State Grid organizes large-scale joint research，Overcame the development of high-performance insulation components、Suppression of motion characteristics of metal particles under high field strength、GIL full piping system flexible design、High reliability seal、Technical difficulties such as precise fault location，Being the first in the world to master the complete set of UHV GIL transmission technology，Promote the comprehensive upgrade of China's GIL seabet casino review transmission technology and equipment，for crossing the river、Technology reserved for advanced compact seabet casino review transmission across seas and densely populated areas。
Zhundong-Wannan、After the Sutong GIL comprehensive pipe gallery project is put into operation，Clean electricity will be more reliable、Efficient、Flexibly integrate into the East China UHV AC ring network，For optimized energy configuration、Guarantee seabet casino review supply、Preventing and controlling air pollution、Promote economic growth、Leading technological innovation has significant comprehensive benefits and long-term strategic significance。For example，After the Zhundong-Wannan project is put into operation，Can reduce coal burning in East China by approximately 38 million tons per year。Construction of Sutong GIL comprehensive pipe gallery project，After the formation of the East China UHV AC ring network，East China will more effectively accept UHV projects including the Zhundong-Wannan Project、Ultra-high voltage DC channel，seabet casino review receiving capacity reaches 69.8 million kilowatts，Can reduce coal consumption for seabet casino review generation by 1 each year.700 million tons，Reducing carbon dioxide emissions 3.100 million tons、960,000 tons of sulfur dioxide、530,000 tons of nitrogen oxides、110,000 tons of smoke，Significantly improve the environmental quality in East China，Provide strong support to win the battle to defend the blue sky。
High investment in UHV seabet casino review grid，High industrial added value，Low consumption of material resources，Significant medium and long-term economic benefits，Has a long industrial chain、Advantages such as strong driving force，Can powerfully drive seabet casino review、Electrical Equipment、Energy consuming equipment、Raw materials and other upstream and downstream industries，Promote the transformation and upgrading of the equipment manufacturing industry，Cultivation of new growth points。estimated，Construction of Zhundong-Wannan Project and Sutong GIL Comprehensive Pipe Gallery Project，Increase the output value of seabet casino review transmission and transformation equipment manufacturing industry by approximately 29 billion yuan，Driving investment in seabet casino review supply and other related industries of approximately 102 billion yuan，Increase jobs 2.80,000，Both the seabet casino review-transmitting provinces and the seabet casino review-receiving provinces can benefit directly。(Reporter Ran Yongping)
