Silicone rubber composite insulators would produce powders on their surface after long-term operation in high humidity environment. In order to study the effect of water ingress into on-site aged silicone rubber on its properties, we used the composite insulator sheds which have operated over ten years in the southern coastal areas as research object. Deionized water immersion tests were conducted on the silicone rubber samples which have been removed their chalking layers to study the effect of water ingress into samples on their mass and physicochemical properties, and the influence of water ingress on the secondary chalking phenomenon of the silicone rubber was discussed. The results show that the silicone rubber samples which have removed their chalking layers could generate new chalking layers after deionized water immersion, whose microstructures and physicochemical properties were close to the naturally formed chalking layers. It is determined that water is the main influence factor which aged silicone rubbers produce powders on their surface again by changing the water temperature of tests, and high temperature can accelerate the generation of chalking layers.
