Insulators are one of the important components in the power system, widely used in transmission lines, substations and other equipment. They are mainly used to support wires and prevent current from passing through supporting structures or grounding, thereby ensuring the safe and stable operation of the power system. Its function and role are not limited to supporting wires, but also play a crucial role in the process of power transmission.
The importance of insulators！
Firstly, insulators have electrical insulation function. It effectively ensures the safety of power equipment by preventing current from flowing along the wire support structure, preventing short circuits or electrical leaks between the equipment and the ground. Insulator materials are usually made of ceramics, glass, or composite materials, which have excellent electrical insulation properties and can withstand high voltage currents without conducting electricity.

Secondly, insulators also have a mechanical support function. In high-voltage transmission lines, wires need to be connected to towers through insulators to prevent them from sagging or swinging due to their own weight or external wind effects. The mechanical strength and weather resistance of insulators enable the power system to operate stably under various environmental conditions, including extreme weather such as wind, rain, and snow.

In addition, the role of insulators in the power system also includes anti pollution and anti-aging functions. Long term exposure to harsh weather and polluted environments may cause insulators to accumulate dust and dirt, which can reduce their insulation performance. Modern insulators usually adopt pollution resistant designs, which can reduce this impact and extend their service life.
