Ceramic insulators are electrical components made from ceramic materials that prevent the flow of electricity. They are commonly used in power lines and electrical equipment to support and insulate wires, ensuring safety and efficiency. Their high resistance to electrical current makes them ideal for high-voltage applications. These insulators can withstand extreme weather conditions and temperatures, making them durable and long-lasting. They are often shaped like discs or rods and are designed to hold wires securely while preventing electrical leakage. High-voltage power lines and electrical substations frequently utilize ceramic insulators for reliable performance.
