A device that is mounted between a conductor of varying potential or between a conductor and a grounding member and that can withstand voltage and mechanical stress. Insulators come in many varieties and shapes. Although the structure and shape of different types of insulators are quite different, they are all composed of two parts: insulation parts and connecting tools.
Insulator is a kind of special insulation control, which can play an important role in overhead transmission lines. In the early years, insulators were mostly used in telegraph poles, and gradually developed into a high voltage wire connecting tower with a lot of disk-like insulators hanging on one end, which is to increase the creepage distance. They are usually made of glass or ceramic, so they are called insulators. Insulators should not fail due to various mechanical and electrical stresses caused by changes in the environment and electrical load conditions. Otherwise, insulators will not play a significant role, which will damage the service and operating life of the whole line.

Product structure and advantages
Porcelain insulator Insulator made of electrical ceramics. Electrical ceramics are baked with quartz, feldspar and clay as raw materials. The porcelain surface of porcelain insulators is usually covered with porcelain glaze to improve their mechanical strength, waterproof infiltration and increase the surface smoothness. Among all kinds of insulators, porcelain insulators are the most commonly used.Advantages of ceramic insulator: It has good chemical stability and thermal stability, strong anti-aging ability, and has good electrical and mechanical properties, flexible assembly.
