The world's tallest power transmission towers were under final checks before they go into trial run today on Zhoushan Islands, which is home to the China (Zhejiang) Pilot Free Trade Zone.
Electricians braved wind, fog and low temperature to check wires on the two 380-metre power transmission towers, the world's tallest, located respectively on Cezi Island and Jintang Island in Zhoushan of east China's Zhejiang Province.
The towers are 52m higher than the Sky Tower.
The 500-kilovolt power transmission and transformation project for the Zhejiang pilot free trade zone in Zhoushan has set 14 world records, aside claiming the world's first cross-linked polyethylene submarine cables.
The project will create two 500-kilovolt power grids connecting Zhoushan with Zhejiang's Ningbo City, so as to provide stronger support for the many export-oriented enterprises in the Zhejiang pilot free trade zone.
