Insulator is a special insulation control, which can play an important role in overhead transmission lines. In the early years, insulators were mostly 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, which were usually made of glass or ceramics to increase the creepage distance. Insulators shall not fail due to various electromechanical stresses caused by changes in environment and electrical load conditions, otherwise insulators will not play a significant role and will damage the service life and operation life of the whole line.
Insulators can be divided into low-voltage insulators and high-voltage insulators according to different voltage levels. High voltage insulator refers to the insulator used for high voltage and ultra-high voltage overhead transmission lines and substations. In order to meet the needs of different voltage levels, different numbers of single (piece) insulators of the same type are usually used to form insulator strings or multiple insulation poles.
