Abstract (en)

[origin: WO9528717A1] This invention relates to an extrusion plant for making a high voltage power cable including a conductor (2, 11) and concentrical layers of extruded polymer insulation and semiconductors. It includes an extrusion head (15, 40, 50) for extruding at least four successive layers - a first, inner layer of semiconductive material (3), at least two layers of insulation material (4, 5; 7, 8, 9) and a second, outer layer of semiconductive material (6) - on top of each other, onto the conductor (2). The head (15, 40, 50) is provided with at least four individual extruder inlet screws (41-44, 46), at least two for the insulation layers and two for the semiconductive layers.
