flexible electric power cable and control.

摘要

Cable flexible electrical control comprising a core surrounded by a sheath of insulating material and in which there are provided at least two conductive lines (1, 2) of signals intended for data transmission, surrounded by a screen (5 ) common, and each of which includes an electrical conductor surrounded by an insulation (4) of foamed insulating material, and at least one line (6, 7) supply, for the power supply and including a electrical conductor surrounded by an insulation, characterized in that - there is formed a non-woven fabric of metallized polymer, electroconductive, around the conductor (1, 2) signal, as a shield (5), without clearances, lines - because in the interstices opposing between the two bus lines (1, 2) signal, there is, externally to the shielding (5), in each case, a line (6, 7) supply, whereby some tightens the shield ( 5), making it penetrate the int respective ersticio, - that the diameters of the conductive lines (1, 2) and signal lines (6, 7) for extending into the interstices between them are matched such that a web is achieved approximately circular cross section of the cable, - in that, positioned adjacent at least one of the conductive (6, 7) supply lines exists at least one braid (11) filler wires (6, 7) with good electrical conduction properties, which extends against the shielding (5) of the conductive lines (1, 2) signal and against a common shielding (10) outside, comprising a nonwoven fabric of metallized polymer, electroconductive and under around the unit comprising the conductive lines (1, 2) of signals, the conductor (6, 7) supply and the braid (1, 2) filler, and lines - that the outer shielding (10) is surrounded by a layer (13) of shield wires with good propi ages of electrical conduction, around which the cover (14) is provided.
