Abstract
The utility model relates to a finest pairwise-twisted sheathed cable comprising conductors, core wires, a cable core, insulating layers, shielding layers, and a sheath layer. Each conductor is formed by a single tin-plated copper wire and the diameter of the conductor is 0.20mm; and the insulating layers coat the peripheries of the surfaces of the conductors. The core wires include the conductors and the insulating layers; and the external diameter of each core wire is 0.30+/-0.03mm. The cable core contains the two core wires that are twisted mutually; the twisting distance is 12mm-15mm and the twisting pitch ratio is 8 to 10; and the direction of the core wire twisting is the left direction. The shielding layers coat the surface periphery of the cable core and the sheath layer is arranged outside the shielding layers. The shielding layers are formed by braiding of aluminium alloy belts; the insulating layers and the sheath layer are made of tetrafluoroethylene-hexafluoropropylene copolymer materials; and the external diameter of the sheath layer is 0.95+/-0.10mm. Compared with the prior art, the provided finest pairwise-twisted sheathed cable has advantages of reasonable lead design, long service life, good short circuit prevention performance, long cable extensibility, and high anti-expansion strength performance.
