Composite Post Insulator


Product Description

The post composite insulator can be effectively used the narrow     corridor to drive down the power supply, which is suitable for the transformation of the city network technology and high voltage power line service.

The post composite insulator has features of good hydrophobicity, anti-ageing; anti-leakage trace and electric erode proof, tensile strength and bending strength, strong mechanical strength, shock resistance good quakeproof and brittle failure proof, light weight, easy to installation.
