Fabricated wallboard for transformer substation

The utility model relates to the technical field of fabricated wallboards, in particular to a fabricated wallboard for a transformer substation. Comprising supporting beams and wallboards, the supporting beams comprise supporting longitudinal beams and supporting transverse beams, the supporting longitudinal beams are fixedly connected to the ground, the supporting transverse beams and the supporting longitudinal beams are perpendicularly crossed to form a frame, and the wallboards are installed between the supporting transverse beams and the supporting longitudinal beams; the wallboard is a cubic frame formed by welding a steel wire mesh, the frame is filled with fireproof materials, the two sides of the steel wire mesh are sequentially and fixedly connected with a sound insulation layer and a decoration layer, and the steel wire mesh is connected with the fireproof layer through a connecting piece. The periphery of the wall plate is in a groove shape, and metal section bars which are spliced into a whole ar
