000000295 520__ $$aNumerous studies have been conducted to understand the effect of insulator profiles on ceramic insulators, whereas for polymer insulators this problem has not sufficiently examined. The research so far has concentrated on material composition. The new investigations into influence of the shape of composite insulators with silicone rubber housings have dealt only-with ageing performance in fog conditions. Rains constitute a major ageing stress for composite insulators. They can wash out low molecular weight components from the surface of silicone rubber, which may lead to loss of hydrophobicity by the insulator surface, increase leakage currents, the development of surface discharges and in consequence, the development of ageing processes. This paper presents investigations into ageing processes of model composite insulators in high-voltage artificial rain chamber. The same housing material — silicone rubber (HTV) — was used to manufacture, the model insulators. The results of the investigations have shown a clear influence of the silicone rubber insulators' profiles on their ageing performance in rain conditions.
