The terminal connection device can be a fully integrated structure, having a pre-installed connection interface, or the terminal connection device can be configured as an adapter which can be mounted in the field to a connection interface.

A single line (6) for a charging cable comprises an open support structure (011, 012) with a longitudinal extent, a conductor braid (2) composed of conductors and an insulating element (3). The conductor braid (2) directly covers the open support structure (011, 012) along its longitudinal extent. The insulation element (3) covers the open support structure (011, 012) and the conductor braid (2). There is at least one duct (4) for a cooling fluid (5) in the single line (6). This duct (4) is formed by the support structure (011, 012) and the conductor braid (2). The insulation element (3) cannot be penetrated by the cooling fluid (5) and is electrically insulating.

A method for preparing an HVDC cable for jointing or termination includes the step of providing a section of an HVDC cable comprising a conductor surrounded by a first semiconducting layer, and at least one insulation layer of a first polymer material surrounding the first semiconducting layer, where the insulation layer comprises conductive volatile by-products. A tape of a second polymer material is provided, where the additional layer comprises conductive volatile by-products. The tape is lapped onto the insulation layer thereby forming an additional layer. Heat is applied to crosslink the additional layer and redistribute the conductive volatile by-products.

Provided is a cable including: at least two signal cables formed of first and second signal cables for differential transmission; a third cable for ground; a fourth cable for power supply; a metal sheet adapted to cover the first and second signal cables; a coating material adapted to house the first and second signal cables covered with the metal sheet, and the third and fourth cables; and a magnetic powder-mixed resin filled into an inner space of the coating material and prepared by mixing magnetic powder with a resin.

An apparatus for transferring electrical current between a first component and a second component includes at least one transfer conductor directing electrical current between the first and second components including a plurality of overlapping conducting layers each arranged in parallel with the directed electrical current and a plurality of insulation layers each disposed between alternating ones of the conducting layers.

The invention relates to an electrical cable for supplying aircraft and similar devices with alternating current having at least partially higher frequencies of preferably 400 Hz. The cable is provided with a central neutral and/or return conductor (1) and at least six phase conductors (2a, 2b, 3a, 3b, 4a, 4b) arranged in a concentrically distributed manner about same, wherein every phase is distributed on two symmetrically opposing phase conductors (2a, 2b, 3a, 3b or 4a, 4b). The neutral and/or return conductor (1) is formed, in a very space-saving manner and with low inductivity, by preferably six individually insulated compact neutral wires (16), the total cross-section of which approximately corresponds to the cross-section of an individual solid neutral wire. In this way, with six-fold redundancy, the risk of a neutral wire failure is reduced, without diminishing the electrical properties with the inductive voltage drop.

A multi-conductor flat cable having a width and a thickness includes a plurality of individual conductors arranged side-by-side. The conductors include first and second power conductors, a neutral conductor, and a ground conductor.
