摘要： A high voltage direct current cable includes at least one electrical conductor, at least one semiconducting layer, at least one stratified insulation made from windings of at least one paper-polypropylene laminate, the stratified insulation being impregnated with at least one electrically insulating fluid having a kinematic viscosity of at least 1,000 cSt at 60EC, wherein the laminate includes at least one paper layer having an air impermeability of at least 100,000 Gurley see. Such a high air impermeability of the paper layer(s) remarkably reduces the swelling of the polypropylene layer(s) during impregnation with a high viscosity insulating fluid, thus preventing delamination, up to the end of the impregnation process for the whole stratified insulation.

摘要： Mass-impregnated electrical cable, particularly for carrying high voltage direct current, having an insulation in which, around the insulating layer impregnated with an insulating fluid, a containing layer is provided broadly includes at least one winding of a tape of a semiconducting elastomeric material, which exerts an effective action of containing the insulating fluid, while preventing formation of micro-cavities within the impregnated insulating layer. The material constituting the tape has high physical-chemical resistance to the degrading action of the components of the insulating fluid, both in the cold state and, in particular, at the operating temperature of the cable.
