Performance of HTV Silicone Rubber under Artificial AC and DC Corona/Ozone Test
Paper in proceedings, 2011

This paper concentrates on presenting the changes of properties of high temperature vulcanized (HTV) silicone rubbers when exposed to 100 hours long corona/ozone treatment in a multi-needle electrode system, as suggested by CIGRE Working Group D1.14 and in detail reported in our former publication. The material samples were treated by either AC or DC corona sources. The HTV samples used in this test contained one type of a commercial HTV silicone rubber (including both post- and unpostcured specimens) based on polydimethylsiloxane (PDMS) as well as model HTV silicone rubbers containing increased amount of methylvinylsiloxane (MVS) and filled with aluminum-trihydrate (ATH) of different proportions. Material characterization methods involving volume and surface resistivity measurements, dielectric response (DR) measurement, as well as tensile tests were adopted to trace the performance changes of the samples induced by the AC or DC corona treatments.
