aterial: fog type glass insulators are primarily made from tempered or toughened glass, which is a specially treated type of glass that has enhanced strength and durability. the glass used is typically resistant to shattering and can withstand mechanical stresses and thermal fluctuations.

design: the insulator's design consists of multiple glass discs or units stacked together vertically, forming a column-like structure. each glass disc is separated from the others by a metal or polymer fitting. this design increases the surface distance along which the electricity must travel, providing higher electrical resistance.

surface treatment:the glass surfaces are often coated with a hydrophobic material to make them water-repellent. this treatment helps prevent the accumulation of water droplets on the surface of the insulator during foggy or rainy conditions. this is crucial because water droplets can form conductive paths, allowing electricity to "leak" across the insulator and reducing its effectiveness.

performance in foggy conditions:the hydrophobic coating on the glass surface helps to repel water droplets and prevent the formation of a continuous conducting path between the conductor and the insulator's supporting structure. this is particularly important in areas with frequent fog or mist, as well as during rainy weather when water can cling to surfaces. by maintaining the insulation properties even in wet conditions, fog type glass insulators contribute to the reliability and safety of the electrical grid.

strength and durability:the tempered glass used in fog type insulators provides good mechanical strength, enabling the insulators to withstand the mechanical stresses caused by factors like wind, ice, and temperature changes. this durability is essential for maintaining the integrity of the transmission lines and ensuring a long service life for the insulators.

maintenance:while fog type glass insulators are designed to resist contamination and leakage, periodic maintenance is still necessary to ensure their proper functioning. cleaning the insulator surfaces to remove dirt, dust, and contaminants can help maintain their hydrophobic properties and prevent electrical leakage.
