Jiangyin

One exists at Jiangyin. It is a section of the 500kV-powerline from the Yan Cheng power station to the Dou Shan substation in the province of Jiangsu. The powerline section running over the river has a span width of 2,303 metres. It is carried by two 346.5 metre tall suspension electricity pylons, each weighing 4,192 tons. They are both identical lattice towers of square cross section with an area of 68 × 68 metres at the base and 8 × 8 metres at the top. The pylons are of the Danube type carrying 4 conductors on the upper crossbar, 312 metres above ground with a length of 77 metres and two conductors on the upper crossbar. The insulator chains are 10 metres long. These pylons, which are both equipped with an elevator, which runs in a cylindrical tube in its center, are much taller than any other electricity pylons built so far and surpass even the Eiffel Tower. On each side of the river are these pylons followed by two anchor towers, for each circuit. They are 55 metres tall, weigh 110 tons and stand on an area of 16 × 24 metres.
