摘要:
The invention relates to a cable (100) comprising at least one radially outer section (110) and at least one radially inner section (120) arranged radially inwards of said radially outer section (110), wherein said cable (100) comprises at least one locking element (130, 130a, 130b, 130c, 130d; 170) which is configured to reduce and/or prevent an axial relative movement between said radially outer section (110) and said radially inner section (120).
摘要:
An electrical cable (1a, 1b, 1c, 1d), particularly adapted to environments for dwelling and/or office use and the like, comprising at least one electrical wire (2) covered with an outer covering layer (7) provided by means of at least one fire-resistant material comprised within the group constituted by leather, hide, synthetic leather, fire-resistant fabrics and/or metallic fabrics.
摘要:
A wiring harness can include a plurality of high-voltage electrical conduction paths, a motor connector provided at one ends of the high-voltage electrical conduction paths, and an inverter connector provided at the other ends of the high-voltage electrical conduction paths. An extra-length portion can be provided at an intermediate portion of the conductor. The extra-length portion can be configured to absorb displacement caused by a force acting upon the wiring harness and forcing it to be extended. The extra-length portion can take a folded shape obtained by folding the conductor.

摘要:
The invention relates to a HF power supply bushing device for linking an HF transceiver to an antenna through an outer medium by means of a symmetrical two-wire line (42). The symmetrical two-wire line (42) is at least partially encapsulated within a central portion of a closed pipe (40) comprising a wall (44) that insulates the symmetrical two-wire line from the outer medium. The invention is of use for supplying power to antennas by means of symmetrical two-wire lines.
摘要:
A power umbilical cable (200) includes one or more axial elongate phases (100) for conducting electrical current, and one or more axial elongate structural components (210) adapted to undergo stress to withstand axial and bending strain applied to the power umbilical cable (200) in operation. The umbilical cable (200) is protected within an outer protection layer (300, 310, 320). The one or more elongate phases (100) include corresponding one or more current conducting cores (20), wherein each core (20) comprises a plurality of mutually abutting conductive metal wires (30), and wherein each current conducting core (20) includes at a central portion therein surrounded by the plurality of conductive metal wires (30). The central portion includes a flexible element (110) operable to enable the wires (30) to move in a radial direction to reduce their strain when the umbilical cable (200) is subject in operation to stress causing the one or more elongate structural components (210) to be axially strained.
