Composite Post Insulator,Polymer Post Insulator
Advantages for polymer post insulator compare to porcelain post insulator: 1. Light weight: the weight of composite station post insulator is almost one third of porcelain station post insulator. 2. Good transportation and installation: Since composite post insulator is light weight and non-brittle, it is easy to transport and install and reduce risk of handling damage. 3. Outstanding pollution performance and flashover resistance. 4. Excellent seismic performance provides safety and reliability. 5. Leakage current control due to hydrophobicity. 6. Low weight and maintenance is free for cost savings. Standards for composite post insulator: Below 245kV we reference IEC62231; it is composite station post insulators for substations with a.c. voltages greater than1000v up to 245kV. We also produce polymer insulator post type in accordance with ANSI C29.19: solid rod fiberglass insulator-Apparatus post type. IEC61109 is commonly referenced by China insulator manufacturers. Voltage class and cantilever strength for composite insulator post type: Our station composite post insulator voltage class includes: 15kV, 25kV, 36kV, 45kV, 52kV, 69kV, 72kV, 110kV, 132kV, 169kV, 220kV, 245kV, 345kV, 400kV, 500kV. Our composite post insulator for station has the following cantilever strength class: 4kN, 6kN, 8kN, 10kN, 12kN, 13.5kN, 15kN. If you need this type composite insulator, please contact With me .
