    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 sec−1. 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： A process for manufacturing a water-resistant telecommunication cable. The cable has a solid and compact element having a water-soluble polymer material having vinyl alcohol/vinyl acetate copolymer having a hydrolysis degree of 60-95% and a polymerisation degree higher than 1,800 and at least one solid low-melting and one solid high melting plasticizers. The process produces continuously the water-soluble polymer material by separately feeding, in sequence, a multi-screw extruder, in the flow direction, with the copolymer and the high melting plasticizer melting and mixing them while transporting them through the extruder, and with the low melting plasticizer, melting and mixing them with the copolymer and the high melting plasticizer, subsequently homogenizing the copolymer and the plasticizers and finally discharging the melt, at a temperature lower than or equal to 205° C. A process for extruding the above PVA based water-soluble polymer material. The process allows extrusion of PVA with an enhanced productivity and reproducibility requiring shorter times for absorbing the plasticizers onto the polymer.
