Abstract

Electric treeing is the electrical pre-breakdown phenomenon which can degrade the insulating ability and limit the lifespan of solid insulations. In this paper, the research work investigates the influence of introducing OvPOSS (Octavinyl-Polyhedral oligomeric Silsesquioxane) nanoparticles on tuning the electric treeing characteristics of polypropylene (PP) under the pulse voltage with the frequency of 200 Hz, including the inception voltage for treeing growth, the electric treeing propagation rate under the pulse voltage of 30 kV. Some measurements, including scanning electron microscope (SEM) and thermal stimulated depolarized current (TSDC), were utilized to analyze the mechanism of the nanoparticle effects of OvPOSS. Finally, the experimental results showed that the addition of OvPOSS nanoparticles can obviously increase the inception voltage of treeing growth and suppress the treeing propagation under 30 kV pulse voltage due to the introduction of deep traps in the OvPOSS/PP nanocomposites.
