Composite line post insulators
Composite line post insulators
Composite line post insulators are electrical components used to support overhead electrical conductors in power distribution and transmission systems. They consist of a core material made of insulating silicone rubber or other polymer materials, surrounded by a weather-resistant, flexible outer shell. They offer several advantages over traditional porcelain or glass insulators, including higher mechanical strength, lighter weight, and resistance to environmental factors such as moisture, UV radiation, and pollution.
