Yangtze River Crossing may refer to one of three
overhead power lines crossing the Yangtze River in the People's Republic of China.
at Jiangyin, Jiangsu Province, China.
Pylons situated at and at . It is a section of the
500kV-power line from the Yan Cheng power
station to the Dou Shan substation in the province of Jiangsu.
power line section running over the river has a span width
of . It is carried by two tall
suspension electricity pylons
each weighing 4,192 tons, and as of April 13, 2004, both are the
tallest electricity pylons
towers even surpass the height of the Eiffel Tower, which is (including antenna) in comparison.
They are identical lattice towers
square cross section with an area of × 68 m at the base and × 8 m
at the top. The pylons are of the Danube
carrying 4 conductors on the lower crossbar, above ground with a
length of and two conductors on the upper crossbar. The insulator chains
are long. These pylons are
both equipped with an elevator
in a cylindrical tube in its center, and a spiral staircase circles
the elevator shaft outside.
On each side of the river are each main span pylon, followed by two
; one for each circuit.
They anchor pylons are each tall, weigh 110 tons and stand on an
area of × .
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.
circuit, 500 kV AC overhead powerline crosses the Yangtze River at
Province, China, built in 1992.
It uses two tall pylons
built of reinforced concrete, which may be the tallest pylons built
out of concrete in the world. They are situated at and at and carry
6 conductors in two levels. The span width is .
Gorges-Changzhou powerline crosses the Yangtze River near
Province, China, at and .
The pylons were built in 2003. The
crossing consists of two tall pylons built as constructions of
tubular steel, which carry two conductors. The span width is .
Close to it, there is a 500 kV AC powerline crossing with a span
width of on probably taller towers and a 110 kV AC powerline
crossing with a span width of . Both AC crossings have 6
