Abstract

Submarine power cables are considered lifelines in wind farm engineering, playing a key role in transporting electric current produced by wind turbines or wave converters. The bending behaviour of a power cable is a complex issue due to both its various materials and multi-layer structures. The copper conductor in the middle of a power cable is especially complex as it is composed of numerous helical copper wires. The influence of the copper conductor on the overall bending behaviour is still not clear due to rare studies regarding this topic. This paper focuses on the pure bending test of a naked copper conductor from a real cable, then theoretical and numerical methods are used to generate the bending stiffness in order to compare it with each other. The pros and cons of each method are clarified and the obtained conclusions will pave the way for the study of the overall power cable.
