ABB wins over $100M power order in China
Switzerland, Zurich: ABB has secured orders worth over $100 million to supply converter transformers and components including wall bushings and circuit breakers for the Lingzhou-Shaoxing ultra high-voltage direct current (UHVDC) transmission link in China.
Switzerland, Zurich: ABB has secured orders worth over $100 million to supply converter transformers and components including wall bushings and circuit breakers for the Lingzhou-Shaoxing ultra high-voltage direct current (UHVDC) transmission link in China.
The link will be the 7th 800 kV UHVDC transmission system in the country and will help to deliver more electricity from remote power plants in China’s interior to growing urban areas, over longer distances and with fewer losses, states the company in the press release.
The long-distance Lingzhou-Shaoxing +/- 800 kV UHVDC transmission project will transfer 8,000 MW of power from Lingzhou in the north-western Ningxia region to Shaoxing in the eastern Zhejiang province, stretching over a distance exceeding 1,700 kilometres.
This will be the world’s first 750 kV ultra-high-voltage alternating current (AC) to 800 kV UHVDC connection, an innovation that enhances the efficiency and capacity of long-distance UHV electricity delivery systems necessary for China’s growing economy.
Converter transformers play a critical role in HVDC transmission, serving as the vital interface between the DC link and the AC network. The products are scheduled to be commissioned in 2016.
