Effect of Nano Titanium in SiR/EPDM Composite on Electrical Surface Tracking Under Incline Plane Test

摘要

Nowadays, the incorporation of inorganic nano-particles such as alumina and silica into polymeric material had produced a better electrical properties than polymer alone. Especially, in minimizing the effects of surface tracking in high voltage insulation material due to environmental stress. However, the investigation on surface tracking with composite of nano-titanium in SiR/EPDM polymeric material still unknown. Therefore, this paper presents the effect of various nano-titanium concentration in SiR/EPDM composite on the electrical surface tracking. The nano-composites have been prepared into several batches for instance unfilled, 1 and 2 vol.% concentration. The properties of nano-composites such as tracking time, leakage current magnitude and surface condition were analyzed under Incline Plane Tracking (IPT) test. The experimental setup was carried out based on the IEC 60587 standard with a constant applied a.c voltage at 4.5 kV_(rms) and 0.6 ml/min contamination flow rate. The results revealed that the effects of nano-titanium in SiR/EPDM composite significantly influenced the properties of surface tracking. The increment of nano-titanium with 1 and 2 vol.% were found to have a good resistance to surface tracking on the composite.
