The insulator is an exceptional insulation control essential in overhead transmission lines. In the early years, insulators were mainly used for power poles and gradually developed into a series of disc insulators hanging on one end of the connection tower of high-voltage power lines, usually made of glass or ceramics, to increase the creepage distance. Insulators shall not fail due to various electromechanical stresses caused by environmental changes and electrical load conditions. Otherwise, insulators will play a minor role and will damage the service life and operation life of the whole line.

Insulators can be divided into high-voltage insulators and low-voltage insulators according to different voltage levels. High voltage insulators are mainly used in substations and high voltage and extra high voltage overhead transmission lines. According to the needs of different voltage levels, it is usually necessary to use different numbers of monolithic insulators of the same type to form an insulator string or multiple insulating poles.
