A secondary bushing with a sleeve for each conductive contact is disclosed. The secondary bushing is secured to a transformer wall by a mounting assembly and comprises a first side and second side. The first side is positioned within the transformer wall and includes a first conductor. The second side is positioned outside of the transformer wall and includes at least one cable connector that is coupled to a power cable. Instead of exposing the conductive contacts of the cable connector and power cable, a sleeve is inserted to insulate and seal each conductive contact.
