Installation of 66 kV XLPE power-optical fiber composite submarine cable and water pipe for the Trans-Tokyo Bay Highway

The manufacturing and the installation of the optical fiber composite submarine cable and water pipe for the Trans-Tokyo Bay Highway were completed in 1993. It was the longest Japanese 66 kV XLPE power-optical fiber composite submarine cable and the first application of optical fiber composite submarine water pipe composed of two hollow galvanized steel armour wires inserted with optical fiber to monitor and control construction sites. This paper describes the application and development of the hollow steel armour wire with optical fiber ribbon and the features of construction and installation of the optical fiber composite submarine cable and water pipe.<>
