The specific embodiment is as follows:

in order to better understand the purpose, structure and function of the present utility model, the present utility model provides a novel high-strength buggy ladle cable with reference to fig. 1 and 2 in the following, which is further described in detail.

As shown in fig. 1 and 2, the buggy ladle cable comprises a copper monofilament 1, a kevlar bulletproof wire fiber line 2, an isolating layer 3, an insulating layer 4, a braiding reinforcing layer 5, a tensile filling piece 6, an inner sheath 7, a mixed braiding layer 8, an outer sheath 9, a ceramic fireproof belt 10 and a galvanized steel wire braiding layer 11 from inside to outside. The conductor structure adopts a braided structure of soft copper wires and Kevlar bulletproof wires which are twisted after being bundled, and Kevlar bulletproof wire fiber wires are added when the conductor is twisted, so that the overall tensile property of the conductor is remarkably improved, the compactness, softness and torsion resistance of the conductor are effectively improved, and the quality problem that a cable core of a buggy ladle cable is easy to break is solved.

The conductor is externally provided with an isolation layer 3, the isolation layer 3 is formed by wrapping PTFE (polytetrafluoroethylene) wrapping tape, an insulation layer 4 is wrapped outside the isolation layer, and the outermost side of a single conductor is provided with a woven reinforcing layer 5. The braided reinforcing layer 5 is braided on the insulating surface by adopting aramid fiber with high tensile strength, high wear resistance and high toughness which is treated by a special process, so that the tensile strength of the insulating wire core is increased.
