Abstract
A wall bushing, comprising a head assembly, a conductive rod, and a connecting terminal sealing and covering the head assembly and the conductive rod. The connecting terminal and the conductive rod are electrically connected. The head assembly includes a transition tank and a transition plate that are connected to each other. An upper end of the transition tank is provided with a first through hole, and a lower end of the transition tank is hole-through. The transition plate is provided with a second through hole. The conductive rod extends through the first through hole and the second through hole. The transition tank and the transition plate are fixedly connected such that an accommodation cavity is formed around the conductive rod and in the transition tank.
