China's first submarine power cable to be laid this year

China's first submarine power cable, also billed to be longest of its kind in the world, would be laid through the Qiongzhou Straits this year.
The cable, which would connect the provincial grids of Guangdong and the southernmost Hainan Island, is expected to be completed in the first half of next year, a China Southern Power Grid (CSG) spokesman said.

The initial construction of the cable began early last year but the substantial part would be implemented this year, he said.

A 34.7-km benthal cable and a 144-km trolley wire would be laid to link Guangdong's Zhanjiang city and Hainan's Chengmai county, official Xinhua news agency said.

The state-owned China Southern Power Grid with a transmission capacity of 600,000 kws, would service about 230 million people in the southern provinces of Guangdong, Yunnan, Guizhou and Hainan and Guangxi Zhuang Autonomous Region, it added.
