Prefabricated substation with incoming and outgoing lines at top

The prefabricated substation comprises a box body, wire conduits are symmetrically inserted in the upper top wall of the box body in a sliding mode, wire outlet holes are formed in the outer walls of the front sides of the two wire conduits, the top ends of the wire conduits located on the same side are fixedly connected with rain sheltering caps, and the top ends of the wire conduits located on the same side are fixedly connected with the rain sheltering caps. The outer walls of the two rain sheltering caps are each provided with an annular rain guiding groove. According to the utility model, through upward or downward movement of the wire conduit, the wire conduit can be moved into the box body when not in use, thereby preventing dust or rainwater from entering the box body through the wire outlet hole to cause damage to equipment in the box body, and through arrangement of the rain shielding cap, rainwater can be prevented from entering the wire outlet hole to cause damage to equipment in the box body.
