Abstract
The invention discloses a novel self-check light-weight cable comprising a cable core and a protective sleeve wrapping the cable core. The cable core comprises nickel-plated conductors and mica tape insulation layers respectively wrapping the conductors. The protective sleeve comprises an outer sheath arranged at the outmost layer. The cable has good corrosion resistance as the conductors of the cable are made of nickel-plated copper wires. The cable has stable heat resistance as the insulation layer is made of polyetherketone resin. Filling ropes are made of non-open net polypropylene tearing material, which reduces the resistance coefficient of the structure part of the cable through a compact pressing structure, increases the cooling effect of the cable and prevents the cable from overheat burning. As sensing fibers are arranged on the mica tape insulation layers and the PPEK insulation layer, whether insulators outside wires are damaged can be accurately detected so as to timely remind maintenance personnel to carry out repairing and reduce the occurrence of accidents. Aluminum wires are copper-clad, which effectively prevents the aluminum wires from wear and oxidation, reduces the cost and the weight of the cable, enables the requirements of a variety of complex situations to be met, and improves the comprehensive usability.
