World's 1st carbon fiber UHV power line starts operation
The world's first carbon fiber ultrahigh-voltage power transmission line, a supporting project for UHV power transmission from Xilingol League of North China's Inner Mongolia autonomous region to East China's Shandong province, went into operation on Dec 10, according to reports from local media NMTV.
The project can increase the power transmission capacity by 6.6 billion kilowatt-hours per year, the media said. With a total length of 14.6 kilometers, the line uses carbon fiber composite core wires which are independently developed by China.
Compared to wire with a traditional steel core, those with a carbon fiber composite core perform better in electric conductivity, are lighter in weight and have high temperature and corrosion resistance.
The operation of the Xilingol League-Shandong UHV AC power transmission and transformation project, which is one of the key projects to alleviate air pollution, will increase the coal power transmission capacity from Xilingol League, and meet the electricity needs in surrounding areas of the Bohai Sea in North China and Yangtze River Delta in East China.
