Glass Insulators 

An insulator is a device installed between conductors with different potentials or between a conductor and a grounded component, which can withstand the effects of voltage and mechanical stress. There are various types of insulators with different shapes. Although the structures and appearances of different types of insulators vary greatly, they all consist of two main parts: insulating components and connecting hardware.

An insulator is a special insulating component that can play an important role in overhead transmission lines. In the early years, insulators were mostly used on utility poles. Gradually, they developed to be used on high-voltage power line connection towers, where one end is hung with many disc-shaped insulators. These are designed to increase the creepage distance and are usually made of glass or ceramics.
