525 kilovolts in a cable system – New Technology

ABB has managed to get to 525 kilovots voltage plastic insulated HVDC cable technology, the company states.
– A significant breakthrough in high-voltage engineering, says Spiesshofer, ABB’s CEO.

There is a new plastic insulated cable systems that ABB’s cable factory in Karlskrona has developed and self-proclaimed successfully tested.

A voltage of 525 kilovolts used for transmission of high voltage direct current (HVDC).

The method should make more efficient electricity interconnections and enable the connection of renewable energy from remote sources.

ABB promises a doubling capacity from 1,000 megawatts to 2,600 megawatts by the method. Transmission losses should be less than five percent when more than two gigawatts of electrical power can be transmitted through 1500 km long cable system.

– Compared with paper wrapped oil impregnated cables required less investment money and less operating money. It is simply cheaper, says Marc Jeroense, development manager for product cables to new technologies.

The system can, according to ABB used on the seabed and below ground and represents a voltage increase of 64 percent.

“This is a significant breakthrough in high-voltage technology that will be of great importance for the integration of renewable energy into the grid and electricity interconnections for power exchange between countries,” said Spiesshofer, ABB’s CEO in a press release. But what does the method for me specifically?

– Due to the threat of climate change, we want more renewable energy and we need to transport energy over long distances. Then it will be possible on this type of cable. It is better for the environment, says Marc Jeroense.
