Pin insulator polymer

11kV pin insulator polymer is the oldest type of insulator in high voltage transmission and distribution lines. Due to its simple manufacture, low cost, easy installation and the ability to reduce the height of the tower (due to the vertical installation of the insulator, the grounding part is below), it is widely used for insulation and supporting conductors in high-voltage overhead power lines in common and polluted areas where the nominal voltage of three-phase power system is 6~35kV and the frequency does not exceed 100Hz.
