    Abstract: An apparatus (100) for damping vibrations in electrical lines (10) through which modulated currents flow has at least one sound or vibration sensor (102) oriented towards the line (10) or attached to the line, at least one actuator (104) connected to the line, and a control circuit (200) which is supplied, via respective signal lines (108), with signals generated by the at least one sound or vibration sensor (102) that represent sound or vibrations. The control circuit controls the at least one actuator (104) via respective control lines (110) such that this actuator counteracts the vibration of the line (10).

    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 method of manufacture for a subsea power cable (100), includes the step of providing at least one cable core (125) having an electrical conductor (110) and an electrically insulating system (120) arranged radially outside of the electrical conductor (110). The method includes adding a liquid material having a polymer, on top of the at least one cable core (125), forming a buffer layer (130); and applying a water barrier (140) radially outside of the buffer layer (130).

    Abstract: A spacer device (20) for holding a cable (22) in a central region of a hollow longitudinal structure has, in one arrangement, a spacer body (21) with a through hole (23). The distance from the through hole to the outer surface of the spacer body varies along the axial direction of the through hole. The spacer body has a region with a maximum diameter. The maximum diameter functions as a pivot point/region for the spacer device in the hollow longitudinal structure, around which the spacer device can rotate when there is relative movement between the hollow longitudinal structure and the cable. The region with maximum diameter can have a curved outer surface to facilitate the rotation and reduce wear on both the spacer device and the inner walls of the hollow longitudinal structure.

    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.
