Method and armoured power cable for transporting alternate current
A method and armored cable for transporting an alternate current at a maximum allowable working conductor temperature, as determined by the overall cable losses, the overall cable losses including conductor losses and armor losses. The cable includes at least one core, including an electric conductor having a cross section area, and an armor surrounding the core along a circumference. The method includes: causing the armor losses not higher than 40% of the overall cable losses by having the armor made with a layer of a plurality of metal wires having an elongated cross section with a major axis, the major axis being oriented tangentially with respect to the circumference; and transporting the alternate current at the maximum allowable working conductor temperature, in the electric conductor having cross section area sized on the overall cable losses including the armor losses not higher than 40% of the overall cable losses.
CABLE AND METHOD OF MAKING THE SAME
A cable that has a cable core with a first armor wire layer and a second armor wire layer. The second armor wire layer is segregated from the first armor wire layer, and an outer jacket is disposed about the second armor wire layer.
Method of making a cable

CABLE
A cable, in particular a cable for the at least partial transmission of electrical energy, comprising several, in particular three, phase cores and at least one further core, in particular a protective core, is proposed, wherein the several phase cores are stranded to form at least one phase bundle and the at least one further core runs outside the at least one phase bundle in the cable.
Coated steel wire as armouring wire for power cable
A steel wire as an armoring wire for a power cable for transmitting electrical power, where the steel wire has a steel core and a non-magnetic coating. The coating has a thickness in the range of 0.2 mm to 3.0 mm and selected from metals or alloys having a melting point below 700 C.
Electric wire structure and method for electromagnetic shielding of electric wire
An electric wire structure keeps down the weight and improves the ease of routing, as well as allows an existing electric wire to be easily provided with measures against electromagnetic waves. The electric wire structure includes: a single or plurality of electric wires; a single or plurality of GND members which are disposed around the electric wires along the electric wires and are grounded at both ends; and a bundling member for directly bundling the electric wires and the GND members which are not covered integrally by a jacket.
Method for manufacturing a composite electric power cable
A method (30) for manufacturing a composite electric power cable (20) includes assembling (32) inner layers (21) of the composite electric power cable (20), where the inner layers (21) have at least one electric conductor (29). The method includes adding (34) a data transmission layer (24) with a plurality of polypropylene bolts (22) and at least one fiber optic element (23), by winding the plurality of polypropylene bolts (22) helically around the inner layers (21) and winding the at least one fiber optic element (23) between at least two of the polypropylene bolts.
MULTICORE CABLE
A multicore cable is provided with coaxial cables, each of which includes an inner conductor, an insulator covering around the inner conductor, and an outer conductor arranged around the insulator. The outer conductor is exposed, and the outer conductors of some of the coaxial cables are covered by grounding conductors that are to be electrically grounded. Each of the outer conductors of the coaxial cables is electrically grounded by contacting the grounding conductor or the outer conductor of another one of the coaxial cables.
LOW INDUCTANCE RADIO HEAD CABLE
