500kV/220kV increase Wando II back to the mixed pressure four loops of the same tower
The project was successfully put into operation in 2004, is the first 500kV/220kV put into operation with the tower four circuit transmission line, running in good condition. The works in the mine design, insulation coordination, the tower structure to optimize the design, foundation type selection and planning, technology has reached domestic leading level. Research and application of the results was awarded the first prize of Science and Technology Award 2006 China Southern Power Grid Company and the China Electric Power Science and Technology Award second prize, and Southern Power Grid's first 500 kV circuit on the same tower four - 500kV Lion ocean to Wuyi transmission the line has been further applications and to improve.
