Zhoushan Island Overhead Powerline Tie, High-voltage power transmission towers in Zhoushan, China
The Zhoushan Island overhead powerline uses two tall steel-lattice towers to carry electrical cables across the water between islands. The towers support high-voltage transmission that delivers power where it is needed on both sides.
Construction began in 2009 when the first tower was built on Damao Island, with the second tower completed the following year on Liangmao Island. This link created a direct electrical connection between the two islands.
The electrical infrastructure demonstrates China's commitment to developing advanced power distribution systems that connect island communities to mainland resources.
The towers are visible from a distance and can be viewed from various positions on the islands or from the water. The best view comes from approaching the structures from different distances to appreciate their scale.
The two towers reach about 370 meters high, making them among the tallest electrical transmission towers built to cross water. This unusual height was necessary to maintain a stable connection across the wide distance without support in between.
