Porcelain insulators are a kind of insulation material used in high voltage power lines. Insulators isolate high voltage conductors in power lines and ensure their safe operation by isolating them from grounding lines.
Porcelain insulators are produced from porcelain materials that are resistant to high temperatures and show high mechanical strength. These insulators are usually produced in long, cylindrical or conical shapes and can be of different sizes and shapes for power lines of different voltage levels.
Porcelain insulators provide high reliability and durability in power lines. These insulators are resistant to environmental factors, especially rain, wind and frost. They also provide high dielectric strength when operating under high voltages.
