1,000 kV UHV First for China 

By on

Jingmen SubstationAt the beginning of the year China put the world's first 1,000 kV UHV transmission system into operation. Transmitting power at over a million volts is just amazing.  Some key facts about the system are:

  • nominal voltage 1,000 kV
  • maximum voltage 1,100 kV
  • 640 km of transmission line
  • two substations
  • one switching station
  • estimated cost US$830 million

If your interested in finding out more the articles below give a good overview of the system and installed equipment.
