This screenshot shows the 1000 kV AC lines, that I was able to recognize it on GE and draw it with “Path” placemarks.
Map of the UHV AC power transmission lines in China
The first 1000 kV ultra-high voltage AC power transmission project in China was Jindongnan - Nanyang - Jingmen 1000 kV UHV AC project.
The Project was approved in August 2006 and started construction by the end of the same year. It was completed in November 2008, put
into trial operation on November 30th and was put into operation in January 6th, 2009. This is the world first 1000kV transmission line in commercial service.

It connects North China Power Grid and Central China Power Grid, starting from Jindongnan Substation in Shanxi Province, passes through Nanyang Substation in Henan Province,
and ends at Jingmen Substation in Hubei Province, with a total length of 640 km and transmission capacity of 3000 MVA at each end.
From "NR Protects China’s First 1000kV UHVAC Link" (site nrec.com):
As the first 1000kV UHV AC project, the State Grid Corporation of China(SGCC) was expecting to master the core technology and possess
the adequate experience on the UHV AC transmission system through the implementation of this project. SGCC required the
manufacturers to make a comprehensive study on the new UHV AC system and propose an appropriate solution for the new system.
As well, a reliable and stable protection and control solution should be provided to keep the continuous operation of the critical project and to
minimize the downtime of this 1000kV UHV AC transmission system.

Currently, an entire network of 1000 kV ultra-high voltage AC lines has been built and continues to be built in China
