In this work, the RTV coatings with different levels of ATH and silica fillers were applied to porcelain suspension insulators for a comparative study of the performance of coated and uncoated porcelain insulators. These coated insulators were exposed to different electrical tests. The test results have been reported based on the role of ATH and silica fillers. The measurement of contact angle is also used to investigate the hydrophobicity properties of coatings. TGA is used to investigate the effect of ATH addition to the samples. It has been found that if only ATH is used as filler, the best performance belongs to the sample with 70 pph ATH. Addition of 10 pph silica also improves the performance of coatings with ATH level between 35 to 70 pph. But it should be mentioned that addition of 10 pph silica to samples with higher ATH level (more than 70 pph ATH) wasn’t beneficial.
