摘要： The invention relates to a workshop (18) for the construction of pre-assembled structures for solar trackers, each structure comprising a support beam, at least two stands supporting the beam and each comprising a support cradle, the two cradles being spaced apart by a predetermined inter-cradle distance. The workshop (18) comprises two consecutive assembly zones (Z1-Z3), and at least two trolleys (20a, 20b) capable of being moved on the ground, for the construction of a single pre-assembled structure, on rolling tracks (19a, 19b) connecting the zones (Z1-Z3) The zones comprise: —an initial assembly zone (Z1) in which the stands are assembled directly on the trolleys (20a, 20b); and a second assembly zone (Z2) comprising two locations (23a, 23b) holding the trolleys (20a, 20b) n position for assembly of the support beam onto the cradles while ensuring that the cradles are spaced apart by said predetermined inter-cradle distance.

摘要： A method for the continuous production of a thin-walled, perforated metal hollow profile with one or more fibre waveguides mounted therein. The method includes supplying of a flat metal strip at a first supply rate to a deforming device, which continuously deforms the metal strip into a metal hollow profile with a slot running in a longitudinal direction. Two opposite edges of the metal strip deformed into the metal hollow profile that lie flush against one another in a contact region extending in the longitudinal direction of the metal hollow profile are continuously welded to one another, drawn off from the welding region and perforated. The method further includes positioning a protective tube reaching into the welded metal hollow profile on the draw-off side to beyond the perforation point and supplying one or more fibre waveguides from one or more fibre unwinders via the protective tube, such that the fibre waveguide or waveguides are introduced into the perforated metal hollow profile from the guide or protective tube downstream of the perforation point in the drawing-off direction. The perforated metal hollow profile with the fibre waveguide or fibre waveguides mounted therein is received in a receiving unit.

摘要： A plug-in coupling for connecting a first double-walled vacuum-insulated cryogenic line to a second. The plug-in coupling has a coupling plug and a coupling socket. The coupling plug can be plugged into the coupling socket, these being retained in a plugged-together state by fixing means. A guide column is arranged on the coupling plug or the coupling socket. The guide column has arranged on it elastic means which, in the assembled state of the plug-in coupling, are subjected to stressing and which subject the coupling plug and/or coupling socket to an elastic force which strives to release the coupling plug and coupling socket from one another as soon as the fixing means no longer hold the coupling plug and coupling socket together. The elastic energy stored in the elastic means ensures that, in the event of an emergency, the coupling plug and coupling socket are quickly released from one another.

摘要： 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).

摘要： The present invention relates to a laminate water barrier which is capable of conducting capacitive currents radially out of the cable thus avoiding breakdown due to induced voltage gradients, comprising a laminate structure comprising a metal foil having a lower and an upper surface area, a first layer of a thermoplastic polymer laid onto and covering the lower surface of the layer of metal foil except for a longitudinal uncovered surface area of the layer of metal foil, and a second layer of thermo-plastic polymer laid onto and covering the upper surface of the layer of metal foil except for a longitudinal uncovered surface area of the layer of metal foil, and wherein the laminate structure is wrapped around the cable core such that the first uncovered surface area of the metal foil faces the cable core and the second uncovered surface area of the metal foil faces away from the laminate structure, and the laminate structure is thermally joined by a heat treatment.

摘要： A solid ring-conductor assemblage (20) blocks water from migrating in the axial direction of an electrical stranded conductor (1). The solid ring-conductor assemblage (20) has a ring and an electrical stranded conductor. The diameter of an initial opening of the ring exceeds an outer diameter of the stranded conductor (1). The solid ring-conductor assemblage (20) is obtained by the process of placing the ring in an installed position where the electrical stranded conductor (1) runs through the initial opening. A compressive force (F) is applied onto the ring (2) in the installed position thereby compressing the ring (2) as well as the portion of the electrical stranded conductor (1) as covered by the ring into a compressed state. The compressed ring and the compressed portion of the electrical stranded conductor bonds as an entity providing the solid ring-conductor assemblage (20). A ring is provided to obtain the solid ring-conductor assemblage; a cable has a stranded electrical conductor where at least one ring is compressed around the electrical stranded conductor; and a method includes manufacturing an electrical stranded conductor arranged with at least one solid ring-conductor assemblage.

摘要： The invention relates to a power cable which comprises a central filler region (13) containing at least one conductor element (10), and additionally comprises at least one strip (16) arranged in said central filler region (13) in the vicinity of the conductor element (10). The cable is equipped with a winding-free energy recovery system (11) which supplies the strip (16) with electric current from the energy available in the conductor (10). The strip (16) has a plurality of elements which generate light from this electric current.
