A power cable of a power transmission wire steel tower is provided to confirm a condition of an insulator and a wire in a control part by connecting a CCTV(Closed-Circuit TV) camera to a cable for communications. A power cable of a power transmission wire steel tower comprises a cable for power sources(12), a cable for communications(13), a spacer(14), and a protective film(15). The cable for power sources is contacted in a control part of a power transmission wire steel tower, is arranged in an inner side of a ground wire(10), and supplies a power source to subsidiary facilities of the power transmission wire steel tower. The cable for communications is arranged in an inner side of the ground wire, and transmits an image signal of a CCTV camera installed in the power transmission wire steel tower to the control part. The spacer supports the cable for power sources and the cable for communications in the inner side of the ground wire. The protective film surrounds the cable for power sources and the cable for communications. |
