U70B-U550B Glass Insulator

Description

1.  It has very high dielectric strength compared to porcelain
2. High resistivity
3. Low coefficient of thermal expansion
4. Higher tensile strength compared to porcelain insulator
5. Transparent in nature the is not heated up in sunlight as porcelain
6. The impurities and air bubble can be easily detected inside the glass insulator body because of its transparency.
7. Glass has very long service life as because mechanical and electrical properties of glass do not be affected by aging.
8. Glass is cheaper than porcelain
