Introduce：The device is a vacuum pressure impregnating equipment. It is mainly applied to coil impregnation treatment of power transformers, vacuum pressure impregnation is a widely applied technology in transformer industry, and has been widely applied at home and abroad. The vacuum pressure impregnation process for transformer can solve many problems in the process of transformer production and application, improve the insulation performance of transformer, improve the strength of transformer coil, and reduce the pollution of ordinary dipping paint to the environment.
