Some back ground knowledge about toughened glass shell :

The toughening process consists in inducing prestresses to the glass shell by a rapid
controlled cooling of the still hot molded glass. The pre-stresses result in compressive forces on the outer
surface layer balanced by tensile forces inside the body of the glass shell.
The presence of permanent outer surface compressive stresses prevents crack formation or propagation in
the glass shell for an unlimited period of time .
The combination of compressive and tensile stresses inside the glass body gives toughened glass
insulators the unique property of always breaking  when overstressed mechanically or electrically. Crumbling of the glass shell always results in small corn-size chunks . the glass shell color are transparent or little green.  and the bid advantage of glass insulator shell is all parts are recyclable . it will hurt the environment .

 

Applications:

Toughened glass insulator U420B can be used as a part of string insulator in transmission lines or substations up to 1000kV ,  the insulator can assembled as suspension string or tension string with related hardwares .

 

Competitive Advantage:

The glass insulators are easy for mass production in modern production lines , and insulation body of glass component are even and easy for quality control .

All insulator parts are recyclable .  Product quality are very reliable . 

insulator shell surface are very smooth , and easy for maintance .

very competitive price will make you satisifie with the budget !
