Products Description
Product Name: Insulator Anti-pollution Flashover Coating RTV
Minimum Order Quantity: 100 pieces
Surface Finish: Glaze, RTV Paint
Standards: DIN/ANSI/IEC
Price: Tiered
After using this product on an insulator, a composite insulator with porcelain (or glass) as the skeleton is formed, which is a reliable configuration solution for improving the external insulation of power transmission and transformation equipment.
It is suitable for external insulation anti-fouling of AC and DC systems with ambient temperatures of -50℃~100℃, various voltage levels, substations and overhead transmission line equipment operating under polluted conditions, to prevent flashover and improve the external insulation level of equipment.
Note:In addition to painted insulators, we also provide other glazed brown insulators.
Product advantages：
1. Excellent hydrophobicity and fast, balanced and durable hydrophobic migration
2. Excellent pollution resistance, the ratio of pollution lightning voltage between coated and uncoated insulators reaches 230%
3. Excellent electrical insulation, electrical corrosion resistance up to TMA4.5 level, flame retardancy up to FV-0 level, anti-arc, and can effectively protect electrical porcelain equipment from damage under abnormal circumstances.
4. High modulus, high strength, super adhesion, acid, alkali, salt and strong oxidant corrosion resistance, good oil resistance
5. Resistant to outerwear, ozone, and environmental erosion, does not peel or crack, and requires no cleaning during the maintenance period
6. Formed on-site and easy to use, it meets the needs of anti-fouling technical measures for power transmission and transformation equipment.
