Heavy equipment experiment-used bending-resistance multifunctional cable

The utility model provides a heavy equipment experiment-used bending-resistance multifunctional cable and belongs to the field of cables. The bending-resistance multifunctional cable includes a high-elasticity insulating rubber protective cable, power wire insulation shielding layers, power wire cores, a signal shielding layer, communication wire cores, control wire cores and a ground wire core; the outer layer of the cable is the high-elasticity insulating rubber protective cable; the ground wire core is arranged at the center of the cable; the power wire cores, the communication wire cores and the control wire cores are evenly distributed at the periphery of the ground wire core; the outer layers of the power wire cores are provided with the power wire insulation shielding layers; the outer layer of the communication wire cores and the outer layer of the control wire cores is respectively provided with the signal shielding layer; and the power wire cores, the communication wire cores and the control wire cores are in spiral distribution. The heavy equipment experiment-used bending-resistance multifunctional cable has the advantages of increased functions and enhanced bending resistance. When the cable is bent at a use site, the wire cores in spiral distribution can automatically compensate axial size changes of the inner and outer sides of the cable.
