Method for manufacturing and laying out phase cores for oil-filled cables and a device for accomplishing same

A device for manufacturing phase cores of oil- filled cables comprising:

• a twisting machine used to obtain said current-carrying core by means of twisting together a number of individual wires, an insulating machine used to apply paper insulation onto said current-carrying core, a vacuum drier, an instrumentation means for making electrical measurements and insulation tests, a drum to receive the insulated current-carrying core, a container for said drum, wherein said drum in installed in said container for rotation, said container provided with a means compensating for temperature variations of the volume of said cable phase core and an insulating compound located inside said container comprising an elastic partition dividing said container into a conserving chamber filled with an insulating compound to protect the insulation of the cable phase core from humidity effects, and a compensating chamber to compensate for temperature variations of the volume of said insulating compound and said cable phase core, wherein said elastic partition is attached to said drum to transform the internal cavity of said drum into a compensating chamber.

A provisional sealed housing container comprising a shell, drum means rotatably mounted within said shell and adapted to receive cables, wherein the internal cavity of the drum is airtight, a lid for sealing said shell, temperature compensating means comprising an elastic partition dividing said container into a conserving chamber and a compensating chamber, and means for providing access between the internal cavity of said drum and said compensating chamber, wherein said temperature compensating means compensates for temperature variations within said conserving chamber.
