World´s most powerful underground power transmission cable system

The commercialisation of the first 640 kV extruded DC underground system with advanced material technology, will increase the maximum power transmission of cable systems by 20% allowing better integration of distant renewable energy sources into the global energy systems. The technology enables the lowest cable weight per installed megawatt (MW) of transmission capacity and the higher voltages provide transmission with low energy losses.

Enabling more power over greater distances with reduced losses, our 640 kV cable technology offers solutions for countries seeking to integrate their energy markets. Interconnectors enable efficient transmission of renewable energy being generated by for example distant solar and wind installations, facilitating international energy trading for greater utilization of power generation. By using cables, efficient power delivery can also be made through densely populated or environmentally sensitive areas. A single pair of 640 kV extruded HVDC cables could for example transmit enough green power to supply three million households.
