ABSTRACT:
Disclosed is installation of an optical fiber composite electric power cable. An installation method of an optical fiber composite electric power cable includes installing an electric power cable including a conductor and an air-blown installation tube therein at an installation region; connecting tubes of adjacent electric power cables to each other, in an electric power cable connection box; and installing an optical fiber unit into the connected tubes by air pressure. Also, a cable structure used for installing the optical fiber composite electric power cable includes a conductor for electric power transmission; an insulator surrounding the conductor; an air-blown installation tube provided outside of the insulator; and a corrosion-protective layer provided to an outermost layer of the cable.
