The Aging Characteristics of Composite Insulators under Salt Fog Conditions

Abstract:

The accelerated aging tests under salt fog conditions were carried out on two types of composite insulators in order to evaluate their anti-aging properties. FTIR spectroscopy, hydrophobicity, and hardness measurements were taken to characterize insulator housings' physical and chemical properties before and after aging. It was found that the aging characteristics were highly dependent on housing profile, aging time, and filling materials.
