Abstract: A tension-resistant electrical conductor includes a central core wire and at least a first inner wire layer and a second outer wire layer arranged over the central core wire. The central core wire is made of copper or a copper alloy. The first inner wire layer includes, in the circumferential direction, an alternating sequence of copper wires and wires having higher tensile strength, arranged over the central core wire, and the second outer wire layer, and any further outer wire layer, is composed exclusively of copper wires.

Abstract: A highly flexible shielded electrical line for high-frequency data transmission in swivel-mounted display units having two current supply wires (20; 21) and/or at least two data wires (18; 19), provides a shielding (35) of non-insulated metallic cables enclosing the wires (18; 19; 20; 21), which are stranded and/or bundled or combined in pairs, in their entirety, [the shielding] being covered externally by a conductive non-woven fabric/mesh/mat (36) electrically contacting the shielding (35) all around, the conductive non-woven mat finally being encased by an external sheath (37) made of silicone rubber (FIG. 3).

Abstract: An electric heating cable or an electric heating tape having insulating sheaths of polytetrafluoroethylene (PTFE) being arranged in a layered structure is provided. At least one of the PTFE sheaths is protected by at least one adjacent insulating layer of a melt processable fluoropolymer.

Abstract: An electric heating cable or an electric heating tape having insulating sheaths of polytetrafluoroethylene (PTFE) being arranged in a layered structure is provided. At least one of the PTFE sheaths is protected against shock by at least one adjacent insulating layer of a melt processable fluoropolymer.

Abstract: An electrical wire or cable has superior mechanical and dielectric properties for applications in the aerospace industry. The wire has a metallic conductor surrounded by at least one layer of polyimide winding tape. A sintered intermediate layer is formed over the polyimide winding tape. Over the insulator is at least one layer of polytetraflucroethylene winding tape having a planoconvex cross section. The resulting construction has a smooth surface that can be marked and is highly resistant to aggressive media, moisture and dirt. As a result, corona discharge and short circuits are avoided.

Abstract: An electrical wire or cable has a metallic conductor surrounded by at least one layer of polyimide winding tape. Over the insulator is at least one layer of polytetrafluoroethylene winding tape having a planoconvex cross section. The outermost layer of the polyimide winding tape has a bond with the polytetrafluoroethylene winding tape. The resulting construction has a smooth surface that can be marked.

Abstract: A high-frequency coaxial cable has a multi-layer insulation made of polymeric materials surrounding a central conductor and having an electrical shielding enclosing the insulation. The individual layers of the insulation are of fluoropolymers, with at least a first layer (2) that encloses the central conductor (1) being made of a fluoropolymer capable of being formed from a melt and an outer second layer (3) being made of a fluoropolymer not formable from a melt. In this cable, the second layer (3) is porous and is inter-engagedly connected with the surrounding shield (4).
