The utility model discloses a transformer convenient to install. Transformer comprising a transformer body, an upper fixing block of an inverted-L-shaped structure is arranged at the top of the transformer body. The bottom of the upper fixing block is fixedly connected with the top of the transformer body through welding. The upper fixing blocks are distributed in bilateral symmetry about the longitudinal center line of the transformer main body; a lower fixing block of an L-shaped structure is arranged at the bottom of the transformer body. The top of the lower fixing block is fixedly connected with the bottom of the transformer body through welding. The transformer body is of a structure with the wide middle and the narrow upper portion and the narrow lower portion, the surface fixing rings are evenly distributed in the middle of the transformer body and are of C-shaped structures, and the bottoms of the C-shaped structures of the surface fixing rings are fixedly connected with the middle of the transformer body in a welded mode. The transformer convenient to install is simpler and more convenient in the installation process, time and energy of a user are saved, and the situationthat the transformer is in poor contact can be avoided.
