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.

Description

It runs over several islands and consists of several long-distance spans, the longest with a length of 2.7 kilometres (1.7 mi) south of Damao Island (Chinese: 大猫岛; pinyin: dà māo dǎo). This span uses two 370-metre-tall (1,210 ft) pylons, which were the highest electricity pylons in the world, until a 500 kV line to Zhoushan from mainland was completed. The north tower on Damao Island was completed in 2009, and the south tower on Liangmao Island (凉帽岛; liángmào dǎo) was completed in 2010. These pylons resemble those of the Messina Strait, but are steel-tube lattice structures.[3]
