The substation insulators is defined as "a device used for electrical insulation and mechanical fixation of equipment or conductors subject to potential differences".
As many types of rear insulators are used in substations and converter stations, depending on the application, such as bus support, smooth reactor support, switchgear, bus, etc.

How to classify insulators?
The conductors of overhead power lines are connected and fixed on the towers by means of insulators and fittings. The insulators used to insulate wires and towers must not only withstand the effects of working voltage but also overvoltage during operation, and also withstand the effects of mechanical force, temperature changes and the surrounding environment, so insulators must be in good condition. Excellent insulation performance and certain mechanical strength. Usually, the insulator surface is corrugated. This is because: First, it can increase the leakage distance (also known as creepage distance) of the insulator, and at the same time, each wave twist can also block the arc; second, when it rains, the sewage flowing down from the insulator will not directly It flows from the upper part of the insulator to the lower part, avoiding the formation of sewage columns and causing short-circuit accidents, and plays the role of blocking the flow of sewage water; third, when the polluted substances in the air fall on the insulator, due to the uneven twist of the insulator, the polluted substances will not be able to It is evenly attached to the insulator, which improves the anti-pollution ability of the insulator to a certain extent. There are many types of insulators for overhead power lines, which can be classified according to the structure type, insulation medium, connection method and bearing capacity of the insulators.
As the world continues to shift towards more sustainable energy sources, the use of composite insulators can play a significant role in promoting sustainable energy development. Their durability and reliability can help to ensure the efficient and reliable transmission of renewable energy sources such as wind and solar power.
