On September 26th, ZhunDong - Anhui & plusmn; 1. 1 million v high voltage dc power transmission project, solar building technology sutong 1000 kv ac uhv GIL ( Gas insulated metal-enclosed transmission lines) Comprehensive utility tunnel project put into operation. These two projects are occupied in the world today the high ground of the power transmission technology in their respective fields, electrical equipment manufacturing capacity in China to realize new leap forward, how about solar panels make the optimal allocation of energy and a wide range of ability has improved. Heat tracing sutong GIL comprehensive utility tunnel construction is an important transmission channel for the first time in the world in the uhv GIL technology, is currently the world's highest voltage level, transport capacity of the largest, the highest technical level long distance GIL innovation project. Comprehensive utility tunnel engineering construction sutong GIL, east China will accept include ZhunDong - can more effectively Engineering, ultra-high pressure and ultra-high voltage dc channel in the south of anhui, no back condole ark by electricity capacity of 69. 8 million kilowatts, solar panels can reduce coal for electricity generation 1 each year. 700 million tons, the salesman carbon dioxide 3 heat exchanger equipment. 100 million tons, 960000 tons of sulfur dioxide and nitrogen oxide 530000 tons, 110000 tons of smoke and significantly improve the east China area environmental quality, to win the battle to provide strong support the blue sky. ZhunDong - After the project put into operation in the south of anhui, with either 60 billion - The ability of 85 billion KWH, can make the east China area to reduce coal each year about 38 million tons. ZhunDong - Project is highest voltage level in the world, in the south of anhui biggest transport capacity, transmission distance, as far as the most advanced technology of HVDC project.
