Abstract
An air pressurized coaxial cabling system is disclosed for carrying electrical cables and air simultaneously to and from underwater junction boxes and electrical elements employed in a nuclear reactor vessel inspection device. An electrical cable is routed to a sealed junction box which is also supplied from a source with pressurized air. The electrical cable and air exit the junction box coaxially and are routed therefrom to an underwater junction box wherein the pressurized air prevents water seepage and allows the use of ordinary electrical connectors and components.
