چکیده:

This paper discusses important parameters for evaluating room temperature vulcanized (RTV) silicone rubber coatings for high voltage insulators of substations and overhead lines. It presents the results of conducted tests for 3 different commercial RTVs which are used by utilities nowadays. Tracking and erosion resistance, loss of hydrophobicity, mechanical strength, thermo-gravimetric analysis, and scanning electron microscopy, have been employed to evaluate these coatings in laboratory. As a final conclusion, RTV-C, which has both ATH and silica fillers
with the filler size about 1 m µ , shows the best electrical, mechanical and chemical performance among available insulators. It is recommended for applying to ceramic insulators in the field.
