ABSTRACT:
The invention relates to a method of manufacturing phase cores for oil-filled cables and apparatus therefor, whereby a current-carrying core is obtained by means of twisting together a number of individual wires, then a paper insulation tape is wound around the current-carrying core and the insulated current-carrying core is reeled on a drum, after which the core is dried, impregnated with an insulating compound and placed in a provisional sealed housing for the period of storage and shipment to the site where the core is to be laid out and inside which the core is subjected to the required electrical measurements and insulation tests. The current-carrying core is placed inside the provisional sealed housing right after it is has been wound with the paper insulation tape.
