Abstract: A method (30) for manufacturing a composite electric power cable (20) includes assembling (32) inner layers (21) of the composite electric power cable (20), where the inner layers include at least one electric conductor (27). The method further includes adding (34) an armoring layer (26) with at least one fiber optic element (23) by winding a plurality of armoring wires (22) helically around the inner layers (21), and winding the at least one fiber optic (23) element between at least two of the armoring wires (22).

Abstract: Termination for a cable for transporting high-voltage or very-high-voltage electricity, comprising a composite end (8) of a cable (1) comprising a free end of a cable, the cable comprising an elongate central conducting element (2) and a plurality of layers arranged successively from the innermost to the outermost coaxially around this conducting element, this plurality of layers comprising an inner semi-conducting layer (3), an electrically insulating layer (4), an outer semi-conducting layer (5), such that part of the layers is stripped starting from a distal end of the free end of the cable, the outer semi-conducting layer (5) being stripped over an axial length greater than the length over which the electrically insulating layer (4) is stripped, such that one end of the outer semi-conducting layer (5) forms a chamfer (14), the cable termination comprising a stress cone (20) provided with an annular lip (22), such that this cone lip (22) covers the chamfer (14) over the entirety of its length.

Abstract: A high-voltage cable sealing end (100) has a primary volume (102) and a secondary volume (104) fluidically connected thereto, which are filled with an insulating fluid. The primary volume (102) and the secondary volume (104) are sealed with respect to the atmosphere surrounding the high-voltage cable sealing end (100). The secondary volume (104) can be disconnected from the primary volume (102) via a separable connection (106) which can be cut off in a fluid-tight manner. A drying agent, which draws moisture out of the insulating fluid, is introduced into the secondary volume (104).

Abstract: A method (30) for manufacturing a composite electric power cable (20) includes assembling (32) inner layers (21) of the composite electric power cable (20), where the inner layers (21) have at least one electric conductor (29). The method includes adding (34) a data transmission layer (24) with a plurality of polypropylene bolts (22) and at least one fiber optic element (23), by winding the plurality of polypropylene bolts (22) helically around the inner layers (21) and winding the at least one fiber optic element (23) between at least two of the polypropylene bolts.

Abstract: A connector (1) for high voltage cables has a metal conductor (11) having a first elongated conductor element having a first end (12a), a second end (12b) and an intermediate section (12c) between the first end (12a) and the second end (12b); an insulating layer (21); and a semiconductive layer (31). The insulating layer is moulded onto the second end (12b) and the intermediate section (12c) of the first elongated conductor element (12) and the insulating layer (21) is provided at a first insulator distance (DI1) from the first end (12a) of the first elongated conductor element (12). The semiconductive layer (31) is provided outside of the insulating layer (21) and the semiconductive layer (31) is provided at a first semiconductor distance (DS1) from the first end (12a) of the first elongated conductor element (12). The first insulator distance (DI1) is shorter than the first semiconductor distance (DS1). The insulating layer (21) is moulded as one single insulating body.

Abstract: A system and method for degassing cables, such as e.g. High-Voltage Alternative Current (HVAC) or High-Voltage Direct Current (HVDC) cables, where the system has a reel having a perforated cylinder wall and sealing elements adapted to seal off the inner space of the reel, a gas duct in fluid connection with the inner space, and a source of pressurised and heated gas fluidly connected to the gas duct. The method incudes winding a cable onto the reel and blow heated and pressurised gas into the inner space of the reel/cylinder.
