(Long Rod)Suspension Composite Insulator

KEY WORDS:High pressure vacuum switch

DETAILS

General

 

Insulator is the most widely used basic components in high voltage transmission and distribution power system, it is use for isolation of live part. Composite insulator is use epoxy rod and rubber sheds external insulation polymer composite insulators. Compare with traditional ceramic and glass insulators, it is more lighter(only about 1/4 to 1/8 of traditional insulator), higher strength(10 times higher than high-strength porcelain insulator), less clearing(anti-water). And it also overcome the short life problem of conventional polymer materials, the life will be several decades. It is the new product in power system.

 

 

Implementation of Standards

 

This product is suitable for AC 220KV and below generation, transmission, substation and distribution system for the insulation of live parts.
