Fog Glass Insulator is a specialized type of electrical insulator designed for high-voltage transmission lines and substations, particularly in polluted or high-humidity environments such as coastal areas, industrial zones, and regions with heavy fog. Its unique double-shed (petticoat) design significantly extends the creepage distance, preventing electrical leakage, flashovers, and contamination buildup—critical for maintaining stable power grid operations
