Pylons of Pearl River Crossing

The pylons of the Pearl River Crossing are three electricity pylons with heights of 240 metres (787 feet), 253 metres (830 feet) and 80 metres (262 feet). They carry the 500kV-three phase AC powerline between Jiangmen and Sha Jiao in Guangdong, China at the crossing of the Pearl River. The 253 metre high pylon was built on an artificial island in the Pearl River and is the highest pylon in the world. The 240 metre high pylon is situated at the east side of Pearl River, while the 80 metre high pylon stands on the west side of the river. The span width of the line between the 253 metre and the 240 metre high pylon is 1547 metres. At this span the line is at its deepest point in a height of 70 metres over the Pearl River. The span width of the two crossbars of the 240 and the 253 metre high pylons are 63.5 metres and 54.5 metres. The pylons at the Pearl River Crossing were built in 1987.
