Nkt develops 1kV submarine cable for wave energy power generation

German cable company Nktor is testing power cables
in Norway for a wave power project.
For this project in Norway, Nkt has developed a dynamic 1 kV cable as well as a semi-dynamic 24 kV output cable
for power output.

The cable is currently being tested in a wave energy pilot project in northwestern Norway, in partnership with Swedish company Waves4Power, which has developed a dedicated wave power system
.

On June 2, 2017, the 24 kV semi-dynamic output cable was connected and began to transmit the power generated by the wave energy to the Norwegian land grid system
.

The cable is also being tested
at the High Voltage Test Center at the RISE Institute in Sweden in collaboration with Chalmers University of Technology.

One of the main challenges for wave power generation is the harsh marine environment
.
For Act, the flexibility and durability of wave power cables has always been a key focus
in the cable development process.

Frida Norrbom Sams, Executive Vice President and Head of Applications for Low- and Mid-Voltage Cables at Nact, said: "The new 1 kV cable is very flexible and can withstand the constant bending stresses
caused by wave movements.
The core part of such a cable has three copper conductors with very low mechanical friction, which, unlike ordinary submarine cables, does not have an armored sheath, but is reinforced with aramid yarn, making it very tough and flexible
