The invention discloses a corrosion-resistant shielded communication cabinet for electric power. The communication cabinet comprises a cabinet body. The middle segment in the cabinet body is provided with a horizontal separator board. The separator board divides the inner part of the cabinet body into two cabinet chambers, namely a first cabinet chamber and a second cabinet chamber. A tin-coated copper wire woven shielding layer covers the outer wall of the cabinet body. A high-temperature-resistant layer wraps the outer wall of the tin-coated copper wire woven shielding layer. The back side of the upper surface of the separator body is provided with five T-shaped coiling buttons in a parallel manner in a left-and-right direction. The corrosion-resistant shielded communication cabinet for the electric power has advantages of high shielding performance, effective lightning prevention function, high safety performance, remarkable high-temperature resistance, high corrosion resistance, effective service life prolonging of the communication cabinet, and effective heat radiation and effective dehumidification on the inner part of the communication cabinet. Normal operation of equipment in the communication cabinet is ensured. The T-shaped coiling buttons can be connected with connecting lines, thereby preventing random arrangement, and sufficiently utilizing a space through arranging the upper cabinet chamber and the lower cabinet chamber. Solar energy is utilized for supplying power to internal equipment, thereby saving energy.
