摘      要：Through the development of marine energy,marine cables are the key equipment for transmission of electrical energy between surface platforms and underwater *** failure is a critical failure mode of marine *** bending performance of the cable conductor has a major influence on both bending and fatigue performances of the overall cable *** study the influence of different types of the conductor cross-section on the bending performances of marine cable conductors,three types of copper conductors with the same cross-sectional area,i.e.,noncompressed round,compressed round,and shaped wire conductors,were *** experimental results demonstrated that the cross-section type significantly affects the bending performances of copper *** particular,the bending stiffness of the shaped wire conductor is the highest among the three conductor *** key evaluation parameters,i.e.,the bending stiffness,maximum bending moment,envelope area,and engineering critical slip point,were selected to compare and analyze the bending hysteresis curves of the three copper *** differences in the key evaluation parameters were analyzed based on the structural dimensional parameters,processing methods,and classical bending stiffness theoretical models of the three copper conductor *** results provide an important theoretical guidance for the structural design and engineering applications of marine cable conductors.
