Now, glass insulators have gained popularity in transmission and distribution systems. Compared to traditional ceramic insulators, glass insulators offer many advantages.

The advantages of glass insulators

Compared to porcelain, it boasts an exceptionally high dielectric strength.

2. Its resistivity is also very high.

Low thermal expansion coefficient.

4. Compared to porcelain insulators, it boasts higher tensile strength.

5. Being transparent, it won't heat up in the sunlight like porcelain.

6. The internal glass insulator, due to its transparency, allows for easy detection of impurities and bubbles.

7. Glass has a long lifespan due to its mechanical and electrical properties remaining unaffected by aging.

Ultimately, glass is cheaper than porcelain.

Although glass insulators have numerous advantages, they are not without their drawbacks.

Disadvantages of Glass Insulators

The glass surface is prone to condensation, which leads to the accumulation of air and dust on the wedge-shaped glass surface, providing a path for the system's leakage current.

For higher voltages, glass cannot be cast into irregular shapes, as internal cooling can lead to internal stresses due to uneven cooling.
