Porcelain insulators are electrical components made from a ceramic material that is both strong and resistant to heat and moisture. They are commonly used to support and insulate electrical wires and equipment, preventing unwanted electrical currents from escaping. Their durability makes them suitable for outdoor use, where they can withstand harsh weather conditions. These insulators come in various shapes and sizes, depending on their specific application. They are often found on power lines and transmission towers, helping to ensure the safe and efficient delivery of electricity. The use of porcelain helps to maintain the integrity of electrical systems by providing reliable insulation.
