The company has described its new offering as the most powerful underground and subsea power transmission cable system ever.

Ulrich Spiesshofer, CEO of ABB mentioned that the technology breakthrough will change the feasibility of renewable energy projects. It would pave way for savings in capital and operational expenses. Plus, it also supports the development of DC grids where ABB removed a key technology hurdle with the development of the hybrid HVDC breaker.

ABB highlighted that its system would pave the way for more power over greater distances with reduced losses. Its new 525 kV cable technology would integrate more renewable energy being generated by distant solar and wind installations.

Citing an example, it mentioned that a single pair of 525 kV extruded HVDC cables could transmit enough power from giant offshore wind farms in to supply two million households.

According to ABB, its new initiative will more than double the power capacity to about 2,600 MW from 1,000 MW. It will also expand the cable’s reach to distances of 1,500km , up from less than 1,000km , while keeping transmission losses under 5%.

The new cable offers a 64% increase over 320 kV, currently the highest voltage deployed for this type of technology, stated ABB.

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.
