Dynamic cables

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.
