ABSTRACT:
An elongated flexible gas-insulated transmission line cable is fitted with pressure-tight termination assemblies at its opposite ends before it is placed on a reel for shipment. The cable is then filled with dry gas, such as nitrogen, at a relatively low positive pressure and the cable is then reeled and shipped. The cable terminal ends are adapted for easy connection to other circuit components without requiring access to the interior of the cable and the terminals permit the purging of the nitrogen gas and the installation of sulfur hexafluoride or some other electronegative gas before the cable is placed into operation.
