Cable joint is a key accessory of high-voltage DC cable, its insulation performance determines the stability of high-voltage DC transmission system. To verify the effectiveness of the charge transport model in calculating the electric field distribution of cable joints, we calculated the mobility of injected charge carriers and the conductivity of ionized charges through blocking experiments, and proposed a charge transport model that simultaneously considered the effects of injected and ionized charges, the undetermined parameters in the transport model were simplified. Then the electric field distribution of the XLPE-EPDM double-layer structure was simulated and calculated by using a simulation model, and the results were compared with the experimental results. The results show that with the increase of electric field intensity, the polarity of charge on the interfacial of the XLPE-EPDM double-layer structure is reversed. The simulation results calculated by the simulation model are in good consistency with the experimental results, which proves the effectiveness of the simulation model.
