Nanosílice como carga en la RTV SR usada para cubrir aisladores

the present research work carries out a study on the influence of nanosilica on room temperature vulcanized silicone rubber (rtv sr) used to coat insulators. considering this objective, the dispersion of nanosilica was observed by means of scanning electron microscopy (mev), the permittivity of the room temperature vulcanized silicone rubber was measured with and without nanosilica for different frequencies and the influence of nanosilica in erosion resistance. leakage currents were also measured during salt spray tests to glass insulators covered with these coatings; the loss of hidrophobicity during the test was also measured and its recovery was analyzed the test was finished.
