Description
40kV station post insualtor are suitable for polluted areas, high mechanical tensile loads, large spans and compact lines. Pollution flashover voltage is 30%-50% higher than that of porcelain and glass insulators of the same level. Superior electrical performance and high mechanical strength effectively improve the reliability of safe operation.

Application
1.Substation
In substations, post insulators are often used as insulating components of high-voltage equipment to support the metal structure and power equipment of the substation. Its main function is to isolate current and ensure the normal operation of the substation.
2.Distribution lines
In distribution lines, post insulators can connect wires, keep the wires isolated from the metal poles, prevent the wires from coming into contact with the metal poles, and avoid dangerous accidents. At the same time, it can also serve as the main structural element supporting the line.
