<p>The present invention relates to a system for laying an extra-high voltage cable in a cable tunnel, and more particularly, to a system for laying an extra-high voltage in a cable tunnel, in which, when a power cable is laid in an underground cable tunnel, a device capable of monitoring a state of a cable and a camera are installed on a moving path, and an incoming state of the cable can be grasped through an image or a measured value at a remote place. According to the present invention, it is possible to prevent a damage to a cable during the process of laying the extra-high voltage cable, prevent a quality dispute between a cable manufacturer and a cable-laying constructor, and grasp a situation of a cable-laying site through a wireless communication network in real time at a short-distance place or a remote place. The system for laying the extra-high voltage cable comprises: a control box (110) which is installed on the ground or in a power cable tunnel (11) to collect information with respect to a state of a cable (23) through a wired/wireless communication network; a remote terminal (120) which receives data from the control box (110) or transmits a control signal to the control box (110) while being carried by a work manager which manages the laying process of the cable (23); and a monitoring device (130) which grasps the state of the cable (23) unwound from a drum (22) and receives data with respect to tension applied to the cable (23) from devices installed inside and outside the power cable tunnel (11) to transmit the data with respect to the state of the cable (23) and the data with respect to the tension to the control box (110) trough the wired/wireless communication network. The state of the cable (23) which is grasped by the monitoring device (130) includes a length of the cable (23) which is unwound from the drum (22), an outer diameter of the cable (23), and an image of the cable (23).</p> |
