Q: What are composite insulators?
A: Composite insulators are high-performance insulators used in a variety of electrical systems. They are made of a core material, such as fiberglass or epoxy, and coated with a weather-resistant material.
Q: What types of composite insulators are there?
A: There are two main types of composite insulators: suspension and line post. Suspension insulators are used to support the weight of overhead power lines, while line post insulators are used to insulate power lines from their support structures.
Q: What are the advantages of composite insulators?
A: Composite insulators have several advantages over traditional insulators such as porcelain. They are lighter weight, have a smaller profile, and are more resistant to weathering and pollution. They also have a longer lifespan and require less maintenance.
Q: What are the disadvantages of composite insulators?
A: Although composite insulators have many advantages, they also have some drawbacks. They are more expensive than traditional insulators, and they are more susceptible to damage from vandalism and impact.
Q: What are the applications of composite insulators?
A: Composite insulators are used in a variety of electrical systems including overhead transmission and distribution lines, substations, and indoor switchgear. They are also used in the railway industry for overhead lines and electrified tracks.
In conclusion, composite insulators have revolutionized the electric power industry by providing a high-performance and durable alternative to traditional insulators. Their benefits far outweigh their drawbacks, making them an excellent choice for a wide range of applications.
