Dynamic cables

Forming the Link to the Offshore Industry

The ocean environment is harsh and extensive movements in both vertical and horizontal directions put a very high demand on the cable. They needed basically a totally new cable construction.

NKT developed a solution with a highly flexible yet extremely strong cable that can move with a buoy or a fish farm and withstand the many wave cycles. All connections are located above sea surface which gives you the best possible security, ease of use and best possible TCO. This is key to be able to harness the power from waves or secure power supply from shore.

This is the cable that makes it all possible, the best cable in the world (for this purpose).

What makes RJIT 0,6/1 kV the best dynamic cable in the world?

Flexibility, durability and reliability
Unique patented construction
Proven in action
Tested by independent laboratories

Through the project NKT Dyncables, NKT and the state-owned Swedish research institute RISE have developed reliable dynamic 1 kV cables optimised for WEC (Wave Energy Converters) and TEC (Tidal Energy Converters). The cables' specifications were set up by several companies that develop wave and tidal power. NKT has since designed, optimised and produced cables that will meet these requirements in a cost-effective manner.

NKT manufactures dynamic cables that meet the requirements for many types of offshore industry. They are, for example, developed to withstand the continuous movements of waves. The dynamic cable range from NKT consists of an extremely dynamic 1 kV cable, intended to be used in sea-based installations, as well as a semi-dynamic 24 kV export cable that connects the installation to land. This range is ideal for wave power plants, but also for other offshore industries in need of a reliable transmission link.

The dynamic cables from NKT are based on our long experience of designing durable universal cables. The development has also required extensive lab and field tests in collaboration with RISE and Chalmers University of Technology in Gothenburg. The core of the cable has three copper conductors and very low mechanical friction. Unlike a regular offshore cable, it does not have armoured sleeves but is reinforced with aramid yarn, making it very tough and flexible.
