Insulators are commonly known as porcelain bottles. They are insulators used to support wires. In the early years, insulators were mostly used for telegraph poles. Slowly developed, many disc-shaped insulators were hung at one end of high-voltage wire connection towers. They are used to increase creepage distance and are usually made of glass or ceramics, called insulators.

Insulators can ensure adequate insulation of conductors, crossarms and towers. Insulators play two basic roles in overhead transmission lines, namely, supporting conductors and preventing current from returning to the ground. It should be able to withstand the vertical direction of the wire in the operation of the load and the horizontal direction of the tension. It is also subject to sun, rain, climate change and chemical corrosion. Therefore, the insulator should not only have good electrical properties, but also have sufficient mechanical strength. The quality of the insulator is very important for the safe operation of the line.
