What is the insulator！

we will explore together the indispensable component in the power system – insulators。
They are the guardians of power transmission, ensuring safe and efficient delivery of electricity to every corner.
The history of insulators can be traced back to the 1870s. With the invention and application of electricity, insulators have played a crucial role in the power system.
The main principle of insulators is to use the characteristics of insulating materials to isolate wires or equipment from supporting structures and prevent current flow.
They enable wires to operate safely under high voltage through special structures and materials.
Insulators usually consist of two parts: the insulator core and the insulator housing.
The insulator core is made of insulating materials such as porcelain, glass fiber reinforced plastic, etc.，while the outer shell is composed of metal components used to connect the insulator to a power pole or transmission tower.
Insulators are mainly divided into three types based on their materials: glass, ceramic, and composite. Each type of insulator has its unique advantages and disadvantages, as well as suitable application scenarios.
