Abstract Oil-paper insulation materials are widely utilized in electrical equipment. Ions, as secondary products of aging process in these materials, may potentially impact the binding properties of oil-paper insulation. To investigate this, molecular dynamics simulations were employed to study the microscale behavior of H₃O⁺, OH^-, Cl^-, and Cu²⁺ containing the oil-paper composite system. A pure oil-paper composite model without any ions was also constructed for comparative analysis. The study delved into the effects of ion incorporation on the oil-paper composite system, focusing on binding energy, hydrogen bonding, and mean square displacement. Results indicate that the presence of ions weakens the binding energy between oil and paper, and this weakening effect is enhanced as the temperature increases, which demonstrates a trend towards a degradation of the insulating properties of the oil-paper composite system. On the other hand, ion intervention promotes the formation of hydrogen bonds, which weakens the binding properties of the oil-paper composite system. However, it also introduces the binding energy with high interaction strength, which between ions and oil, into the composite system. This effect, along with intermolecular hydrogen bonding, contributes to sustai-ning the overall stability of the system, and furthermore, enhancing it. The findings of this work provide a new insight into the machanistic role of ions in oil-paper insulation systems, and offer a theoretical basis for the optimization of oil-paper insulation materials' performance.
