Toughened glass is used to make these kinds of insulators. The glass material is heated up and after the melt and cool bath, it offers a very high dielectric strength up to 140kV/cm. The toughened glass suspension insulators are widely used for high voltage transmission (≥ 500 kV) around the world. They have very high resistivity and one of the most advantages is that the faulty or sparked insulator can be easily detected and spotted due to the transparent design.
