Single-Phase Isolation Switch

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.

Advantages for composite line post insulator:

Compare to porcelain line post insulator, composite insulator line post is the ideal solution for compact line applications in urban areas and composite line post insulator is also ideal for upgrading the capacity of existing lines with a narrow right of way – by increasing the voltage or the number of circuits. It also has the following key advantages:

1. Can be installed on steel, concrete and wood poles

Overhead insulated circuit overvoltage protector

The application of composite anti-wind insulators can be seen in electrical power transmission and distribution systems where they are used to prevent power outages caused by wind-induced movement of electrical conductors. They are particularly useful in areas with high wind speeds, where traditional insulators may not be effective. The composite material provides excellent mechanical strength, making it resistant to damage from wind and other environmental factors, and helps ensure the reliability and stability of the electrical
