Embodiment
Below in conjunction with drawings and Examples, the technical solution of the utility model is explained in detail.
Please refer to accompanying drawing 1 ~ 3; a kind of light-duty photoelectricity composite power cable; comprise and put outermost oversheath 7; inside by oversheath 7; lock armo layer 6, inner covering 5 successively; described inner covering 5, for extruding inner covering, because extrude good than wrapping lining-layer of the radial water-resisting of inner covering and cable core protective effect, forms better protective effect to composite core cable like this.Inner covering 5 inside is provided with four cable cores, 1# cable core 101 respectively, 2# cable core 102, 3# cable core 103, 4# cable core 104, each cable core is tangent with the inwall of inner covering 5, 1# cable core 101 in four cable cores, 2# cable core 102, 3# cable core 103 equal diameters, larger than 4# cable core 104 diameter, and every two adjacent cable core outer walls are tangent in four cable cores, gap in the middle of four cable cores is provided with two light unit 4, the diameter of two light unit 4 small one and large one, wherein large diameter smooth unit and 1# cable core 101, 2# cable core 102, 3# cable core 103 is tangent, the light unit of minor diameter is tangential on the less 4# cable core 104 of diameter, 2# cable core 102, 3# cable core 103.Described inner covering 5 inside is provided with filler 3, and described filler 3 is greasy for preventing water.
