69 kv polymer post insulator Features: 
1.The mounting dimensions of top and bottom of insulator correspond to the corresponding pillars and can be used interchangeably.

2.The core is made of rod with high temperature acid resistance. Special coupling agent is painted on interface between core and silicone rubber
3.High anti-aging performances which is perfect for utilization under conditions of high altitude. 
4.The arcing corona ring well distributes the electric field along the insulator’s axe to prevent corona phenomenon and secure the insulator from heavy damage in end fitting in case of flashover.
