Y series(10KV) high-voltage asynchronous motor stator adopts external press-fit structure. The stator winding adopts Class F insulation material, and the end has reliable fixing and binding. During the manufacturing process, it has undergone multiple inter-turn pulse voltage test and ground withstand voltage test. Germany's advanced vacuum pressure impregnation solventless paint equipment and process (VPI) treatment. Therefore, the insulation performance of the motor is excellent and reliable, the mechanical strength is good, and the moisture resistance is strong.
