Wall bushing assembly

The invention provides a wall bushing assembly. The wall bushing assembly includes a bushing, connecting flanges sealing end parts of two ends of the bushing and a conducting rod coaxial with the bushing, the conducting rod has conducting rod penetrating-out sections penetrating out of conducting rod penetrating holes of the connecting flanges, one sides of the connecting flanges, which are back to the bushing, are provided with stretching devices used for axially stretching the conducting rod, the wall bushing assembly also includes end part sealing covers fixed on the connecting flanges in asealed manner and covering the conducting rod penetrating-out sections and the stretching devices, the end part sealing covers have current guiding components leading out current on the conducting rod, and elastic conductive connection structures are axially elastically supported between the conducting rod penetrating-out sections and the current guiding components. The elastic conductive connection structures are elasti
