Finite Element Analysis of Tensile and Temperature Rise Characteristics of IOPPC Cable
In order to obtain the characteristics of the mechanical tension and current temperature rise of the new IOPPC composite fiber optic cable(Insulated Optical Phase Conductor)during erection,mechanical and electro-ther-mal finite element simulations are performed.Firstly,a multilayer stranded geometry model of the fiber optic cable is established,and a high precision mesh is used to divide the cable into sweeping hexahedra,and tensile loads are ap-plied to it;then,a steady-state electro-thermal model considering conduction,convection and radiation is established,and the rated load capacity is applied to it.The finite element calculation results show that the maximum strain of the optical unit is 1.09%under 95%rated tensile force,which does not exceed the fiber strain window,and there is no monofilament fracture during the tensile process;the overall temperature distribution of the fiber optic cable is uniform at 855A rated load flow rate,which is about 82.3°C,and there is no local temperature overheating point.The research in this paper can provide a reference for the design,development and operation and maintenance of new fiber optic ca-bles for power transmission lines.
