Due to artificial operation and poor sealing performance during the assembly of oil-related equipment in some substation, the shed on composite insulator used in the auxiliary equipment may deform due to the contact with insulating oil. In order to further study the influence of insulating oil on the composite insulator shed and analyze the cause of its deformation, we used insulating oil to treat silicone rubber for shed, and investigated its volume change, chemical structure, hydrophobicity, mechanical properties, and electrical properties. The results show that the insulation oil increases the volume of silicone rubber, while decreases its elongation at break, tensile strength, tear strength, and hardness, which relates to the swelling of silicone rubber. According to the study, using oil dropping device and insulator to simulate the deforming process of the shed, we propose a method of recovering the deformation of the shed by heat treatment.
