Silicone rubber long-lasting anti-fouling flash paint, also known as room temperature vulcanizing (RTV) silicone or PRTV anti-fouling flash paint, is a coating specifically designed for anti-fouling flash work on insulators in power systems or external insulation of electrical equipment. Among them, PRTV anti-fouling flash paint, also referred to as long-lasting anti-fouling flash paint, boasts superior performance indicators compared to RTV anti-fouling flash paint, including hydrophobicity, electrical properties, and physical and mechanical properties.
Key characteristics of the long-lasting anti-fouling and anti-flashover silicone rubber coating include:
1. Excellent hydrophobicity and rapid, even, and durable hydrophobic migration, even under adverse weather conditions (rain, fog, dew, drizzle), the coating surface will not form a continuous water film.
2. High anti-soiling flashover voltage, arc-resistant, leakage tracking-resistant, and excellent electrical insulation properties.
3. High strength, excellent adhesion, and resistance to corrosion from acids, alkalis, salts, and strong oxidizing agents.
4. ozone-resistant, UV-resistant, and resistant to environmental aging; does not peel or crack.
5. In-situ formation, easy to use, meeting the needs of on-site anti-pollution technical measures for power transmission and transformation equipment.
6. Long-lasting operation, easy maintenance, no cleaning required during the validity period, high efficiency.
Silicone rubber long-lasting anti-fouling coating is mainly used on transmission and transformation equipment of voltage levels below 750KV, such as suspended insulators (porcelain and glass),支柱型绝缘子, switches, circuit breakers, lightning arresters, transformers, coupling capacitors, wall penetration sleeves, and various porcelain components on indoor transformer equipment in humid areas.
During construction, avoid operations under conditions of fog, condensation, precipitation, snowfall, and other humid weather, as well as windblown sand. The construction temperature should be maintained above -20℃. Before construction, the insulator surface should be cleaned thoroughly and kept dry. For greasy substances that affect the adhesion of the coating, use an appropriate cleaning agent or procedure. The recoating of failed coatings should be determined based on the adhesion of the coating. Ensure that the recoating is even, smooth, without accumulation, dripping, bubbles, streaks, defects, or missed spots.
Overall, silicone rubber anti-fouling and anti-arc paint plays a crucial role in the anti-fouling and anti-arc work of the power system, providing effective protection for the normal operation of transmission and transformation equipment.
