- Abstract
- Corrosion accounts for 52% of the recorded breakdown of insulators utilized in transmission lines, which may interfere with the reliability of power utilities. The CeO2 conversion coating, CeO2-ethylene propylene diene monomer, EPDM composite coating, and Perfluoropolyether PFPE lubricating oil-infused hydrophobized CeO2 composite surfaces were developed on the insulator surface to address these challenges. The properties of these three kinds of structures are compared based on the persistence of coating over insulators installed in a highly contaminated environment. PFPE lubricating oil-infused hydrophobized CeO2 composite surfaces show excellent performance over other approaches. A lubricating oil-infused hydrophobized CeO2 composite of thickness 35.4 & mu;m exhibits contact angles 60 & DEG;, 85 & DEG;, and 160 & DEG;, and contact angle hysteresis of 12 & DEG;, 10 & DEG;, and 4 & DEG;, respectively, after accelerated thermal aging. The proposed approach presents self-healing and corrosion resistance (corrosion rate 0.3 x 10(-3) mm/Y, I-corr 1.2 x 10(-7)), post-accelerated thermal aging. The research outcome is expected to pave the way for incredibly robust insulator coatings.
