The invention relates to the technical field of power cabinet equipment, in particular to an outdoor special power cabinet and aims at solving the technical problem that a protective shell at the topof an outdoor distribution cabinet for communication is easily damaged to affect the service life of the distribution cabinet. In order to solve the technical problem, the invention provides the outdoor special power cabinet. The outdoor special power cabinet comprises two first support plates, wherein the tops of the two first support plates are fixedly connected through a first fixed plate; thetop of the first fixed plate is fixedly connected with a movable plate through a telescopic device; the top of the movable plate is fixedly connected with a base through a damping device; the top of the base is fixedly connected with a cabinet body; and two sides of the base are fixedly connected with fixed devices. According to the outdoor special power cabinet, a support frame of the distribution cabinet is improved and the impact force on the cabinet body is reduced, so that the influence on the control effect of a motor due to the damage to the top of the cabinet body can be avoided, thereby prolonging the service life of the cabinet body and improving normal operation of the distribution cabinet.
