Product Description

Light Weight Substation Post Insulator 66kv Composite Suspended Insulato


Quick Detail: 

66kV Composite Suspended Insulator



Composite polymer insulator is composed of epoxy glass fiber core rod, silicon rubber shed and metal parts.
Composite polymer insulator is of high strength and light weight. A synthetic insulator is 1/5 of that of porcelain insulator, but the circum-tensile strength of insulator is very high. Generally, it can be above 6000mpa.
Its umbrella skirt is an organic polymer structure of silicone rubber.Therefore, it has a strong anti-pollution performance.

The product has reliable structure and will not damage the core rod. It belongs to the rod-shaped insulation structure.
