Purpose: Aerodynamic glass insulators are primarily used in high-voltage transmission lines. Their design resists strong winds, reduces vibration, prevents ice buildup, and enhances self-cleaning capabilities. They are ideal for harsh weather conditions (e.g., windy or frigid regions), ensuring line stability and safety.
