What are the 4 types of insulators?
Electrical engineering and power transmission systems classify insulating materials into four primary classifications based on their chemical composition and physical application. The first is ceramic or porcelain insulators, traditionally utilized in high-voltage overhead power lines for exceptional weather and thermal resistance. The second is glass insulators, offering high dielectric strength and transparency that simplifies visual inspections for internal fractures. The third is polymer or composite insulators, constructed from fiberglass rods covered by silicone rubber sheds, prized for their lightweight durability and pollution resistance. The fourth is mica and mineral-based insulators, used extensively in high-temperature industrial motors, transformers, and electronic circuitry components.
