ABSTRACT:
A high voltage, gas filled, pipe type electrical cable and method of manufacture thereof. The cable comprises a plurality of insulated conductors, each conductor having a central gas passageway and being gas permeable. The conductor is wrapped with tapes impregnated with an insulating oil, and the wrapped tapes are encircled by gas permeable layers and skid wires. Three of such insulated conductors are encircled by a gas impermeable pipe, and the pipe and the conductor passageways are filled with an insulating gas under pressure above atmospheric pressure so that both the interior and exterior surfaces of the wrapped tapes are subjected to such gas. Preferably, the gas is a mixture of sulfur hexafluoride and nitrogen at a pressure of at least 200 psig. The tapes are impregnated with the oil and drained before they are wrapped around the conductor so as to provide gaps between the tapes which are substantially filled with the gas.
