One exists at Jiangyin, Jiangsu Province, China. Each pylon is situated at 31°58′17″N120°3′12″E / 31.97139°N 120.05333°E / 31.97139; 120.05333 and at 31°57′4″N120°2′53″E / 31.95111°N 120.04806°E / 31.95111; 120.04806. It is a section of the 500 kV power line from the Yanchengpower station to the Dou Shan substation in the province of Jiangsu. The power line section running over the river has a span width of 2,303 m (7,556 ft). It is carried by two 346.5 m (1,137 ft) tall[1]suspension towers, each weighing 4,192 tonnes.[citation needed] (for comparison, the towers even surpass the height of the Eiffel Tower, which is 324 m (1,063 ft), including antenna). They are identical lattice towers of square cross section with an area of 68 m (223 ft) × 68 m at the base and 8 m (26 ft) × 8 m at the top. The pylons carry four conductors on the lower crossarm, 312 m (1,024 ft) above ground, with a length of 77 m (253 ft) and two conductors on the upper crossarm. The insulator strings are 10 m (33 ft) long. These pylons are both equipped with an elevator which runs in a cylindrical tube in its center. A spiral staircase circles the elevator shaft outside.
On each side of the river are each main span pylon, followed by two anchor towers; one for each circuit. The anchor pylons are each 55 m (180 ft) tall, weigh 110 tonnes and stand on an area of 16 m × 24 m (52 ft × 79 ft).
Construction of the pylons started on November 8, 2002. They were completed on April 13, 2004. On November 18, 2004, the power line went into service.
