Review of Insulation Failure of Offshore Wind Power Cables Based on Multi-stress Effects

The performance of offshore wind power cables degrades with time due to mechanical stress such as tension, torsion, and vibration, which can result in financial losses and even operational accidents. This paper summaries the properties and operating circumstances of wind power cables, as well as the current progress on defect detection. The failure mechanism of composited insulation of offshore wind power cables under multiple pressures is critically important for insulation failure and condition assessment.
