Abstract
This review explores the reconnaissance of RTV (Room Temperature Vulcanizing) silicone coating for ceramic insulators in live-line maintenance for Ultra High Voltage (UHV) transmission lines. It addresses the significance of live-line maintenance in ensuring the reliability and safety of electrical infrastructure, particularly focusing on the role of ceramic insulators and the challenges they encounter, such as pollution flashover. The properties of RTV silicone coating, including its hydrophobicity, high dielectric strength, and pollution resistance, are discussed. Advantages and challenges associated with its application are highlighted, along with comparative studies assessing its performance against traditional coatings or untreated insulators. The review also examines various application techniques, field trials, and case studies, evaluating the durability, reliability, and environmental considerations of RTV silicone-coated insulators. Finally, future directions for research and development in this area are suggested, emphasizing the importance of optimizing coating formulations and exploring novel application techniques to enhance the reliability and performance of ceramic insulators in UHV transmission systems.
