Zhoushan Island Overhead Powerline Tie
The Zhoushan Island Overhead Powerline Tie is a 220 kV three-phase AC interconnection of the power grid of Zhoushan Island with that of the Chinese mainland. It runs over several islands and consists of several long distance spans, the longest with a length of  south of Damao Island. This span uses two  pylons, which were the highest electricity pylons in the world, until 500kV line to Zhoushan from mainland was completed. The north tower on Damao Island (, ) was completed in 2009, and the south tower on Liangmao Island (, ) was completed in 2010. These pylons resemble those of the Messina Strait, but are steel-tube lattice structures. Coordinates
