Embodiment Construction
[0013] In order to deepen the understanding of the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, which are only used to explain the present invention and do not limit the protection scope of the present invention.
[0014] Such as figure 1 As shown, the present invention is a special power supply cable for cranes, including a sheath 2, five conductors 1 are arranged in the sheath 2, and an insulating layer is arranged between each conductor 1 and the sheath 2 3. The wire cores of the five conductors 1 have the same thickness, and the insulating layer 3 ensures that the outer diameter of the insulation of the power supply cable is consistent, and the outer diameter of the insulation is consistent to ensure the roundness of the cable, so that the cable The movement ensures the concentricity and the safe operation of the cable. The insulating layer 3 and the sheath 2 are adher...

The invention discloses a power supply cable special for a crane, which comprises a sheath, wherein five conductors are arranged in the sheath, an insulation layer is arranged between each conductor and the sheath, the insulation layer and the sheath are adhered together, filling strips are arranged in a space enclosed by the five conductors; cores of the five conductors are consistent in thickness, the power supply cable formed by the insulation layer has consistent insulation outer diameters; and the filling strips are plastic strips or rubber strips. According to the power supply cable, the sheath and the insulation layer are adhered together, and the conductors, the cores and the sheath are linked together, thus the accident that the conductors or the insulation cores break down the sheath in an up-down movement process of the conductors due to out of synchronization of the conductors, the cores and the sheath is avoided. According to the power supply cable, insulation outer diameters are consistent, roundness of the finished cable is ensured, and the concentricity of the cable during moving up and down is ensured. The filling strip among the conductors ensures that the cable is more firm.
Description
technical field [0001] The invention relates to a cable, specifically a power supply cable, a special power supply cable for cranes. Background technique [0002] Ordinary cables are just a layer of insulation on copper or aluminum conductors, braided and sheathed, usually video cables or network cables. Usually the insulation layer and the sheath layer of the cable are separated, so that when the cable moves up and down, it is easy to cause the conductor or the insulated core to break through the sheath layer, and the exposed insulated core and conductor are easy to cause accidents. The inconsistency of the outer diameter of the insulation leads to the non-concentricity of the movement, which poses a safety hazard. Contents of the invention [0003] In order to solve the above problems, the present invention provides a special power supply cable for cranes. The outer diameter of the insulation of the cable is consistent to ensure the roundness of the cable, t...
