The application of insulators

Insulator is one of a special insulation products, which can play an important role in overhead transmission line. In the early years, insulators were mostly used in electric telegraph poles, but now they are mostly used in high and low voltage electrical equipment.

Insulators can be divided into low-voltage insulators and high-voltage insulators according to different service 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 multi section insulating pillars.
