Product Description

 

Product Description

The glass insulators usually are manufactured at high temperatures by mixing the different materials, including lime and quartz powder, and then it suddenly cools in the mold. This action ("Toughening" causes tightening of the glass). In this way, a glass insulator is obtained. 
Advantages and Disadvantages of Glass Insulators
Advantages:
1. The glass insulators have higher resistant to breaking as compared to the ceramics and its mechanical compressive strength is 1.5 times higher than ceramics.
2. The electrical resistance is much higher than that of ceramic insulators (between 500 kV/cm and 1000 kV/cm).
3. Thermal expansion coefficient of glass insulators is small, and its relative deformation is very low due to temperature variation. Also, glass insulators before cracking are completely crushed, so it is easy to detect faulty insulators on the floor. Contrary to ceramic insulators, any crack or hole created during manufacturing process is detectable in the glass insulators.
4. Due to transparency, some or sun rays pass from the glass insulator, thereby decreasing the degradation of insulator.
Disadvantages :
1. The mechanical durability of glass insulators against bending forces is slightly less than that of ceramics.
2. By a strong impact all insulator will break.
3. Any impurity in composition or any temperature variations of environment during storing or operation leads to breaking the insulator.
4. The glass insulators absorb contaminations easier than other types of insulators.
5. The moisture easily distilled on the surface of the glass insulators.
