N2 - A 35 kV three-core AC XLPE submarine cable is studied in this paper on account of the electromagnetic thermal coupling effects. Based on the dependence of permittivity and conductivity of XLPE on temperature, we construct a thermoelectric model of the submarine cable. The electric and thermal characteristics are calculated by the finite element analysis (FEA). The results indicated that the conductor current determines the conductor loss, lead sheath loss, and armor layer loss. As the current increases, the temperature of cable and the temperature gradient of the insulation obviously increased. Consequently, in the XLPE layer, the electric field near the conductor increased, while the electric field near the screen layer decreased. The conductor voltage plays an important part in the dielectric loss. The electric field of the XLPE layer increased with the increase in voltage. As a result, the current density of insulation was enhanced. However, the temperature presented a slight increase with the increase in voltage.
