220kv post insulator

2. 220kv post insulator advantage:


1).Long-duration resistance aging and leakage tracking.


2).Small volume,light weight,sheds have good elasticity,not broken,con venient transportation and installation, economy.


3).Secure and reliable operation on high mechanical strength.


4).The end fitting and FRP rod are connected with imported end-fitting crimping equipment ,ensures the mechanical performance of the 220kv post insulator.


5).We use hot dip Galvanizing steel fitting ,the 220kv post insulator thickness of the zinc more than 100 μm.


6).Perfect bound between 220kv post insulator silicone rubber and the rod.
