Abstract
A kind of power transmission cable of pointing out torsion degree, comprise an insulating sleeve and at least one conductor, any conductor to be all arranged in insulating sleeve and with insulating sleeve walk abreast extend insulating sleeve outer wall in be provided with a groove, groove and insulating sleeve walk abreast and extend, and groove internal fixtion is provided with a minute surface reflective tape.Minute surface reflective tape is made up of a mirror face stainless steel band, or comprises a plastic tape, and the outer surface of plastic tape is provided with the chemical Ni-plating layer after polishing.Minute surface reflective tape and insulating sleeve bond.When power transmission cable twists, insulating sleeve and minute surface reflective tape wherein are all distorted, and minute surface reflective tape is by ray cast to different directions, and workmen or inspection personnel can find the torsion degree of power transmission cable easily.Torch can be utilized to irradiate at night, during the radiation direction generation significant change of the reflection of minute surface reflective tape, namely can judge the torsion degree of power transmission cable.
Description
Technical field:
The utility model relates to electricity field, particularly relates to cable, particularly power transmission cable, particularly a kind of power transmission cable of pointing out torsion degree.
Background technology:
Power transmission cable often needs to lay longer path, and when laying, cable torsion in a circumferential direction can affect its mechanical strength.In prior art, cable can not provide it to reverse the instruction of degree.
Summary of the invention:
Technical problem to be solved in the utility model is to provide a kind of power transmission cable of pointing out torsion degree, described thisly points out the power transmission cable of torsion degree will solve power transmission cable in prior art can not to show the technical problem that it reverses degree.
This power transmission cable of pointing out torsion degree of the present utility model, comprise an insulating sleeve and at least one conductor, conductor described in any one to be all arranged in described insulating sleeve and to extend with insulating sleeve is parallel, wherein, a groove is provided with in the outer wall of described insulating sleeve, described groove and insulating sleeve walk abreast and extend, and groove internal fixtion is provided with a minute surface reflective tape.
Further, described minute surface reflective tape is made up of a mirror face stainless steel band, or comprises a plastic tape, and the outer surface of described plastic tape is provided with the chemical Ni-plating layer after polishing.
Further, minute surface reflective tape and insulating sleeve bond.
Operation principle of the present utility model is: when power transmission cable twists, insulating sleeve and minute surface reflective tape wherein are all distorted, minute surface reflective tape is by ray cast to different directions, and workmen or inspection personnel can find the torsion degree of power transmission cable easily.Torch can be utilized to irradiate at night, during the radiation direction generation significant change of the reflection of minute surface reflective tape, namely can judge the torsion degree of power transmission cable.
The utility model is compared with prior art, and its effect is actively with obvious.The utility model arranges minute surface reflective tape in the insulating sleeve of power transmission cable, when power transmission cable twists, insulating sleeve and minute surface reflective tape wherein are all distorted, minute surface reflective tape is by ray cast to different directions, and workmen or inspection personnel can find the torsion degree of power transmission cable easily.Torch can be utilized to irradiate at night, during the radiation direction generation significant change of the reflection of minute surface reflective tape, namely can judge the torsion degree of power transmission cable.
Accompanying drawing illustrates:
Fig. 1 is radial section structural representation of pointing out the power transmission cable of torsion degree of the present utility model.
Embodiment:
Embodiment 1:
As shown in Figure 1, power transmission cable of pointing out torsion degree of the present utility model, comprise an insulating sleeve 1 and at least one conductor 2, conductor 2 described in any one to be all arranged in described insulating sleeve 1 and to extend with insulating sleeve 1 is parallel, wherein, be provided with a groove in the outer wall of described insulating sleeve 1, described groove and insulating sleeve 1 walk abreast and extend, and groove internal fixtion is provided with a minute surface reflective tape 3.
Further, described minute surface reflective tape 3 is made up of a mirror face stainless steel band, or comprises a plastic tape, and the outer surface of described plastic tape is provided with the chemical Ni-plating layer after polishing.
Further, minute surface reflective tape 3 and insulating sleeve 1 bond.
The operation principle of the present embodiment is: when power transmission cable twists, insulating sleeve 1 and minute surface reflective tape 3 wherein are all distorted, minute surface reflective tape 3 is by ray cast to different directions, and workmen or inspection personnel can find the torsion degree of power transmission cable easily.Torch can be utilized to irradiate at night, during the radiation direction generation significant change of the reflection of minute surface reflective tape 3, namely can judge the torsion degree of power transmission cable.
