Pin insulator is the oldest kind of insulator in high voltage transmission and distribution lines.Due to its simple manufacturing, low cost, simple installation and ability to reduce tower height (because the insulator is installed upright, the ground part is below), it is widely used as insulation and support wire for high voltage overhead power lines in ordinary and polluted areas of three-phase power system with nominal voltage of 6 ~ 35kV and frequency of not more than 100Hz.
