The ends of the cryostat in the assembled state as well as the superconductive cable located in the same are attached on fixed parts of the transmission link. At least at one end of the cryostat, there is gaplessly connected to the same a tube body which is bent by an angle of at least 180° and likewise consists of two metal tubes arranged concentrically in relation to one another, between which a vacuum insulation is provided. The superconductive cable protruding from the cryostat is arranged in the tube body at room temperature in such a way that it runs at least in the direct proximity of the wall of the inner tube of the tube body that has the greater bending radius.
Abstract: A method for attaching a contact element to the end of an electrical conductor is provided. In the method electrically conductive material is shaped to form a contact element with a variable shape. The end of the bare conductor is firstly moved into an at least approximately vertical position. Particles of an electrically conductive material are then applied at a high speed to the upwardly projecting front-side end of the conductor in the axial direction thereof that the material of the conductor connects to the electrically conductive material to form a compact structure which is connected to the material of the conductor in a mechanically fixed and electrically conductive fashion. Additional particles of the electrically conductive material are applied to the compact structure, and the metal body is shaped mechanically to form the contact element.

The legs (41a, 41b) are configured to be provided on respective sides of the pipeline (1). The clamping device has a releasable tensioning device (48) connected to one of the legs (41a, 41b). The clamping device (40) has a first state, in which the ends (41c, 41d) of the first and second legs (41a, 41b) are provided at a first distance (d1) away from each other. The clamping device (40) has a second state, in which the tensioning device (48) is tensioned, causing the ends (41c, 41d) of the first and second legs (41a, 41b) to be at a second distance (d2) away from each other, the second distance (d2) being larger than the first distance (d1). The clamping device (40) has a template hole (42) provided in one of the legs (41a, 41b).
Abstract: An umbilical for subsea applications has at least one longitudinal internal element and a sheath, the sheath is formed by extrusion.

Abstract: A flange assembly for supporting a cable has a flange body and an armor retainer. The flange body and the armor retainer are configured to support a cable by compressing an armor layer of the cable against the armor retainer. The armor retainer and the flange body are separate pieces, that are removably attachable to one another.
Abstract: The present arrangement replaces passive components of a multi-mode fiber optic channel, such as a typical prior art cassette (i.e. connectors & short lengths of fibers) with active cassettes that have components therein that receive the optical signal from a first transmitting transceiver, convert the signal to an electrical signal, route that signal appropriately within the cassette and re-send an optical signal out from the opposite of the cassette into the infrastructure harness. This results in a localized optical signal boost at a mid-channel location.
Abstract: A high pressure cable reinforcement sleeve is provided having two or more bracket elements that are capable of forming a sleeve for surrounding a cable joint, wherein each bracket element has an outer wall and at least one inner protruding wall element.
Abstract: A medium-voltage or high-voltage power cable includes an elongated electrical conductor element, a first semiconducting layer, an electrically insulating layer, and a second semiconducting layer.
