Silicone-based composites have been used to fabricate high power insulators
for outdoor applications. During operation, partial discharges occur which
locally increases the temperature up to 400 ºC. These increments in the
temperature are detrimental of the lifetime of the device. In the present work,
MgO and AlN particles have been added to silicone rubber to increase the heat
conductivity of the device. In addition to thermal conductivity tests, inclined
plane and laser tests were carried out to observe the improvement in the
lifetime of the material. High energy laser was uses as an alternative for inclined
plane tests, showing the same trend. As a result, the introduction of AlN particles
resulted in the highest increase in heat conductivity.
