ABB, the leading power and automation technology group, has successfully developed and tested a 525 kilovolt (kV) extruded high-voltage direct current (HVDC) cable system to make renewable energy installations more efficient and cost-effective.
The new cable offers a 64 percent increase over 320 kV, currently the highest voltage deployed for this type of technology.
The 525kV cable system can be deployed in subsea and underground applications, making it ideal for efficient power delivery through densely populated or environmentally sensitive areas or coastal and open-sea applications.
ABB will present the 525kV extruded HVDC cable system at the Cigré technology symposium in Paris, from August 25-29, 2014.
