The present invention relates to an electric cable installation apparatus. It includes a first driving part which touches the lower surface of a cable to be installed on a cable tray and a second driving part which touches the upper surface of the cable in the upper part of the first driving part. The cable is installed along an installation direction by the rotational motion of first and second conveying belt installed to the first and second driving part. The cable to be installed is arranged between the first and second conveying belt. The cable is transferred in the installation direction so that it can be installed, by using the torque of the conveying belt.
