Abstract: A vibration damper is proposed with two damper halves which enclose a passage opening in the assembled state and, in the installed position, bear against a component which is guided through the passage opening. The damper halves have corresponding latching means which permit an attachment of the vibration damper to the component. Each damper half has in each case one collar, which collars, in the assembled state of the vibration damper, are arranged at opposite ends of the vibration damper. The vibration damper can be mounted simply, even retrospectively. Moreover, the vibration damper can also be released again without damage.
Abstract: The invention relates to a power cable comprising at least one conductor element (10) and which additionally comprises at least one strip (16) arranged on at least one portion of the length of said conductor element (10).

Abstract: A cable distributor for individual cables that are shielded by an electrically conductive shield. The cable distributor has an electrically insulating outer housing, which receives a connection piece at which at least two individual cables are connected to each another. The shields of the connected individual cables are connected to each other by means of an electrically conductive shield housing, as a result of which a continuous shielding of the current-carrying parts of the cable distributor is achieved. A method for producing such a cable distributor is also proposed.

Abstract: A cable tie has a band and having a tensioning device which is integrated in the band and which divides the band into a first and a second region, each of which regions has a toothed portion. A cable channel, or a component, to which an object, such as for example a cable harness, is to be fastened can remain in the fitting position because both ends of the cable tie can be plugged into cable locks from one side. No tools are required for the fitting of the cable tie.

Abstract: An extended Direct Electric Heating system includes a conduit arrangement for transporting fluid from at least one subsea well apparatus to a topside or onshore location/The conduit arrangement has at least one Direct Electric Heating conduit section arranged adjacent to at least one heat traced conduit section in a longitudinal direction of the conduit sections between a subsea connection point and the at least one subsea well apparatus.
Abstract: A method is provided for electrically conductively connecting a contact part to a conductor having a multiplicity of individual wires includes inserting the conductor into a cavity in the contact part and lowering a tool for friction stir welding onto the contact part. The tool for friction stir welding is moved on the contact part in a plane, thus giving rise to a planar cohesive connection between the contact part and the conductor. In this way, a direct cohesive connection of a stranded conductor and a contact part is produced without the need for an additional part such as a sleeve, for example, to prevent the stranded conductor from “sticking out”.
Abstract: An assembly having a tube and at least one optical cable with the optical cable being placed inside the tube. The tube has an inner diameter D and in that the optical cable has an outer diameter d, the ratio d/D ranging from 0.10 to 0.80.
Abstract: A system for stiffening a structure has at least one pair of tie rods (3), each tie rod (3) of the pair of tie rods (3) having a first end (4) fastened to the structure (2) and a second end (5), and at least one device (6) for tensioning the tie rods (3) having a deformable linking element (7) fastened to the second end (5) of each tie rod (3) so as to connect the tie rods (3). An actuator (10) is configured to deform the linking element (7) so as to make it pass from an inactive configuration in which the tie rods (3) are in a first state of tension to an active configuration in which the tie rods (3) are in a second state of tension, different than the first state of tension.

Abstract: A method for creating a flexible transition joint between HVDC-MI cables having different diameters. The central wires of the conductors are thermally joined by a conical connection piece. The strands of the layers of stranded wires surrounding the central wires are rewound, cut and thermally joined along their respective lay lengths. The stranded are sanded/ground along the lay length of the strands to form a smooth uniform transition having the same slope as the conical connection piece. A paper lapping machine is used to form an insulation patch over the transition joint.

Abstract: A reinforced water barrier over a joint between power cables is suited for subsea cables having different water barrier/sheathing designs. The reinforced water barrier has an intermediate water barrier made of lead or a lead alloy which stretches over the joint and is attached to the underlaying water barriers of the joined cables, and which is reinforced by being coated with a layer of polyethylene based adhesive followed by a layer of polymeric outer sheathing. The adhesive layer and the layer of polymeric outer sheathing are thermally set by a heat treatment.

Abstract: A vacuum-insulated line (200) has an inner and an outer corrugated hose (101, 102) which are separated from one another by an evacuated intermediate space (103). One of the corrugated hoses is encased with a wound hose (201). The wound hose (201) prevents the line (200) from becoming elongated when it is charged with pressure during the transport of a medium. The wound hose (201) furthermore protects the line against external mechanical loads or damage. The wound hose simultaneously protects the corrugated hoses against excessive bending.
