An insulated electrically conductive element (1) for the aerospace field has an elongate electrically conductive element surrounded by at least two layers, said two layers being an electrically insulating layer (4) surrounding the elongate electrically conductive element (2) and a first semiconductor layer (5) surrounding said electrically insulating layer (4), at least one of the layers having at least one fluoropolymer.

The present invention discloses a mobile dedicated cable for a medical Computed Tomography (CT) bed, comprising an inner sheath layer, a first Teflon® belt, a signal cable layer, a second Teflon® belt, a braided layer and an outer sheath layer, which are coaxially arranged from inside to outside in sequence. The inner sheath layer comprises a PVC filling strip wrapped by the first Teflon® belt, and a plurality of bulletproof filaments arranged in the center of the PVC filling strip. The signal cable layer comprises a plurality of signal lines evenly arranged therein, each of which are circumscribed with the first Teflon® belt and the second Teflon® belt, and with two signal lines adjacent thereto. The cable of the invention has improved flexibility and working life, thereby being suitable for the medical CT bed.

Disclosed is an armored cable assembly including a core having a notched assembly tape about a plurality of conductors. A metal sheath surrounds the core.

A transmission cable provided includes a conductor, a protective layer, and a wrapping layer. The protective layer covers the conductor. The wrapping layer surrounds the protective layer. The protective layer covers the conductor to increase a bending strength of the transmission cable.

Bundled cables and methods for preparing bundled cable are disclosed herein. In the method, a plurality of subunits is wound about a central member. The subunits include a subunit jacket made of a first thermoplastic composition and has a first outer surface, and the central member includes a central member jacket made of a second thermoplastic composition and has a second outer surface. A metal element is provided at an interface of the second outer surface and the first outer surface of the subunits. The metal element is heated such that at least one of the first thermoplastic composition or the second thermoplastic composition forms bonds with the other of the first thermoplastic composition or the second thermoplastic composition.

An electrical cable for use as a substitute for mineral-insulated cables in nuclear facilities is described herein. The cable may include at least one conductor, insulation, a jacket, and an armor shell. In some embodiments, the conductor may comprise a stranded conductor of one of various grades. The insulation may comprise phlogopite or muscovite mica tape that may be helically or longitudinally applied in overlapping concentric layers around at least one conductor. The jacket may comprise a woven glass braid applied over insulation surrounding one or multiple conductors. The armor may comprise hermitically sealed metallic armor applied around the other components of the cable, thereby forming an exterior of the cable. The inorganic materials utilized may be configured to limit the creation of adverse and/or undesirable elements instigated by transmutation from neutron irradiation exposure.
