Klaasisolaatidel, also known as glass insulators, are electrical insulators made from glass. They are primarily used in overhead power lines to prevent electrical current from flowing into the support structures, such as wooden or metal poles. The insulating properties of glass are critical in these applications, as they prevent energy loss and ensure the safe and efficient transmission of electricity.

Glass insulators have a long history of use, dating back to the early development of electrical power grids. They are typically manufactured by pressing or blowing molten glass into a desired shape. Common shapes include the bell or cap-and-pin insulator, designed to provide a secure mounting point for the conductor wire. The surface of the glass is often treated to resist weathering and contamination, which can reduce its insulating effectiveness.

The advantages of glass insulators include their excellent dielectric strength, resistance to corrosion, and transparency, which allows for visual inspection for damage. However, they can be susceptible to thermal shock and mechanical stress. In recent decades, advancements in materials science have led to the development of alternative insulators made from porcelain and composite materials, which offer different sets of advantages and disadvantages. Despite the advent of newer technologies, glass insulators remain in use in many parts of the world, particularly in older infrastructure.
