The invention discloses a pay-off device for electric power construction, which comprises a first support plate, the lower surface of the first support plate is fixedly connected with the upper surface of the second support plate through four first electric push rods, and the four first The electric push rods are respectively located at the four corners of the upper surface of the second support plate, and the lower surface of the second support plate is provided with a moving device, the moving device includes two first bearings, and the two first bearings are respectively clamped on the second support plate The left and right sides of the lower surface and the two first bearings are both sleeved with a first rotating shaft. The pay-off device for electric power construction is provided with a first electric push rod, a moving device, a first motor, a clamping plate, a second electric push rod, a first gear, a second gear and a second motor, and the cable reel Move and rotate, avoid pulling the cable manually, thereby reducing the labor intensity of the worker, saving the physical strength of the worker, shortening the laying time of the cable, thereby improving the laying efficiency of the cable.
