Massive Construction of Submarine Cable in Hainan

China’s first submarine power cable will be laid through the Qiongzhou Straits this year, connecting the provincial grids of Guangdong and the southernmost Hainan Island. A 34.7-kilometer benthal cable and a 144-kilometer trolley wire will be constructed to link the Gangcheng transformer substation in Guangdong’s Zhanjiang City and the Fushan transformer substation in Hainan’s Chengmai County with a 500-kilovolt alternating current grid. The project will cost 2.1 billion yuan ($280 million).

When completed in the first half of 2009, the submarine power cable is expected to be the longest of its kind in the world.
