Kurzfassung
Integration of renewable energies into existing grids must be safe and reliable including the subsea power-transmission cables. Therefore, this paper determines the purely mechanical ultimate strength of a DC and an AC power transmission cable under axial load. Aspects concerning the electrical functionality of these cables are outside the scope of this paper and failure of the cable is defined as rupture of the cable following ultimate strength. At first, the individual components of the cable are tested to obtain the engineering stress strain relationships to derive material model data for the numerical simulation of the components and cables. The latter is compared to full-scale experimental results of the power transmission cables. Very good comparison of the numerical and experimental ultimate strength of the cables was achieved with the presented straightforward procedure.
