Partial Discharge (PD) is one of the main causes of degradation in polymer insulation materials under high-voltage systems. To enhance the insulation resistance against PD, an impregnation process using Polydimethylsiloxane (PDMS) filled with nano-sized silicone dioxide (SiO₂) particles was conducted. This study aims to evaluate the effect of SiO₂ concentration variation on the viscosity of PDMS and its connecting with the partial discharge inception voltage (PDIV) and breakdown voltage (BDV) of Polyvinyl Chloride (PVC) insulation material. The impregnation process was carried out with immersion times of 1, 12, and 24 hours to determine the optimal impregnation duration. The result indicates that increasing SiO₂ concentration leads to higher PDMS viscosity, which affects the impregnation effectiveness on PVC. The highest PDIV and BDV values were obtained at 1.5 wt% SiO₂ with an impregnation time of 24 hours, where BDV reached 23.2 kV and BDV increased by approximately 46% compared to untreated PVC. These findings indicate that PDMS impregnation containing SiO₂ can improve the electric field distribution and enhance the dielectric strength of PVC insulation under high-voltage stress.
