Project abstract

High voltage dynamic cables used for power transmission in offshore environments are currently limited to 66kV. This project will conduct a systematic study on dielectric materials used in the construction of submarine cables, with the aim of evaluating their use in the design of dynamic cables with nominal capacity above 66kV.

In this first phase, lasting 24 months, emphasis will be given on studying the mechanical properties of three dielectric materials, assessing their sensitivity to temperature, aging and, especially, to the cyclic loads that are imposed by floating units under the action of waves and sea currents.

Experimental and theoretical approaches will be used. A simplified structural model for a dynamic high-voltage cable will be developed, capable of evaluating the fatigue life of these materials in representative oceanic scenarios.
