Three phase pad mounted transformer is a combination transformer that integrates transformer body, high voltage bushing, high voltage fuse and tap changer. With vacuum pressure gauge, oil level gauge, thermometer and pressure release valve and other inspection operation equipment, so that it can better detect and check the internal situation of the transformer. It has the characteristics of easy operation, simple installation, stable power supply and so on.
