To study the interface ageing characteristics of hybrid porcelain insulator, the hybrid porcelain insulators, type A and type B composite porcelain insulator were conducted 1 000 h water-boiling ageing test, and the leakage current, infrared temperature rise, and bonding property of the aged samples were measured. The interface bonding mechanism of the hybrid porcelain insulator was analyzed through porcelain block simulation. The results show that during the water-boiling process, the leakage current of the hybrid porcelain insulator changes slightly and no temperature rise occurs, the bonding property is CC-5 level, and the anti-ageing performance of the interface is good. The simulation test show that after coating the silane coupling agent, the surface roughness of the porcelain increases by 821.4%, and the formation of Ti-O-Si chemical bond enhances its physical interlocking with the silicone rubber. At the same time, more -OH groups appear on the surface of porcelain block, which can better chemically bond with silicone rubber, achieving good interface bonding effect.
